You are looking for examples, code snippets, sample applications for Spring Integration? This is the place.

Spring Integration Samples

Welcome to the Spring Integration Samples repository which provides 50+ samples to help you learn Spring Integration. To simplify your experience, the Spring Integration samples are split into 4 distinct categories:

• Basic
• Intermediate
• Advanced
• Applications
• DSL

Inside of each category you'll find a README.md file, which will contain a more detailed description of that category. Each sample also comes with its own README.md file explaining further details, e.g. how to run the respective sample.

| For additional samples, please also checkout the Spring Integration Extensions project as it also provides numerous samples.

Happy Integration!

Note

This (main) branch requires Spring Integration 6.0 or above. For samples running against earlier versions of Spring Integration, use the 5.5.x and other branches.

The project requires now Java 17 or above. To open the project in the IDE, use its import option against a build.gradle file from the root project directory.

Categories

Below is a short description of each category.

DSL

This directory holds demos/samples for Spring Integration 4.0 Java Configuration as well as the Java DSL Extension.

Basic

This is a good place to get started. The samples here are technically motivated and demonstrate the bare minimum with regard to configuration and code to help you to get introduced to the basic concepts, API and configuration of Spring Integration. For example, if you are looking for an answer on how to wire a Service Activator to a Channel or how to apply a Gateway to your message exchange or how to get started with using the MAIL or XML module, this would be the right place to find a relevant sample. The bottom line is that this is a good starting point.

• amqp - Demonstrates the functionality of the various AMQP Adapters
• barrier - Shows how to suspend a thread until some asynchronous event occurs
• control-bus - Demonstrates the functionality of the Control Bus
• enricher - This sample demonstrates how the Enricher components can be used

• xml - Example demonstrates various aspects of the Xml support using an XPath Splitter, XPath Router, XSLT Transformer as well as XPath Expression support
• xmpp - Show the support for XMPP (formerly known as Jabber) using e.g. GoogleTalk

Intermediate

This category targets developers who are already more familiar with the Spring Integration framework (past getting started), but need some more guidance while resolving more advanced technical problems that you have to deal with when switching to a Messaging architecture. For example, if you are looking for an answer on how to handle errors in various scenarios, or how to properly configure an Aggregator for the situations where some messages might not ever arrive for aggregation, or any other issue that goes beyond a basic understanding and configuration of a particular component to address "what else you can do?" types of problems, this would be the right place to find relevant examples.

• async-gateway - Usage example of an asynchronous Gateway
• dynamic-poller - Example shows usage of a Poller with a custom Trigger to change polling periods at runtime
• async-gateway - Example shows usage of an Asynchronous Gateway
• errorhandling - Demonstrates basic Error Handling capabilities of Spring Integration
• file-processing - Sample demonstrates how to wire a message flow to process files either sequentially (maintain the order) or concurrently (no order).
• mail-attachments - Demonstrates the processing of email attachments
• monitoring The project used in the Spring Integration Management and Monitoring Webinar Also available on the SpringSourceDev YouTube Channel
• multipart-http - Demonstrates the sending of HTTP multipart requests using Spring's RestTemplate and a Spring Integration Http Outbound Gateway
• rest-http - This sample demonstrates how to send an HTTP request to a Spring Integration's HTTP service while utilizing Spring Integration's new HTTP Path usage. This sample also uses Spring Security for HTTP Basic authentication. With HTTP Path facility, the client program can send requests with URL Variables.
• retry-and-more Provides samples showing the application of MessageHandler Advice Chains to endpoints - retry, circuit breaker, expression evaluating
• splitter-aggregator-reaper A demonstration of implementing the Splitter and Aggregator Enterprise Integration Patterns (EIP) together. This sample also provides a concrete example of a message store reaper in action.
• stored-procedures-derby Provides an example of the stored procedure Outbound Gateway using Apache Derby
• stored-procedures-ms Provides an example of the stored procedure Outbound Gateway using Microsoft SQL Server
• stored-procedures-oracle Provides an example of the stored procedure Outbound Gateway using ORACLE XE
• stored-procedures-postgresql Provides an example of the stored procedure Outbound Gateway using PostgreSQL
• tcp-async-bi-directional - Demonstrates the use of Collaborating Channel Adapters for arbitrary async messaging (not request/reply) between peers.
• tcp-client-server-multiplex - Demonstrates the use of Collaborating Channel Adapters with multiple in-flight requests/responses over a single connection.
• travel - More sophisticated example showing the retrieval of weather (SOAP Web Service) and traffic (HTTP Service) reports using real services
• tx-synch Provides a sample demonstrating the use of transaction synchronization, renaming an input file to a different filename, depending on whether the transaction commits, or rolls back.

Advanced

This category targets advanced developers who are quite familiar with Spring Integration but are looking to address a specific custom need by extending the Spring Integration public API. For example, if you are looking for samples showing how to implement a custom Channel or Consumer (event-based or polling-based), or you are trying to figure out what is the most appropriate way to implement a custom BeanParser on top of the Spring Integration BeanParser hierarchy when implementing a custom namespace, this would be the right place to look. Here you can also find samples that will help you with adapter development. Spring Integration comes with an extensive library of adapters that allow you to connect remote systems with the Spring Integration messaging framework. However you might have a need to integrate with a system for which the core framework does not provide an adapter, so you have to implement your own. This category would include samples showing you how to implement various adapters.

• advanced-testing-examples - Example test cases that show advanced techniques to test Spring Integration applications
• dynamic-ftp - Demonstrates one technique for sending files to dynamic destinations.
• dynamic-tcp-client - Demonstrates a technique for dynamically creating TCP clients.

Applications

This category targets developers and architects who have a good understanding of Message-Driven architecture and Enterprise Integration Patterns, and have an above average understanding of Spring and Spring integration and who are looking for samples that address a particular business problem. In other words, the emphasis of samples in this category is 'business use cases' and how they can be solved via a Messaging architecture and Spring Integration in particular. For example, if you are interested to see how a Loan Broker process or Travel Agent process could be implemented and automated via Spring Integration, this would be the right place to find these types of samples.

• cafe - Emulates a simple operation of a coffee shop combining various Spring Integration adapters (Including Router and Splitter) see Appendix A of the reference documentation for more details. Implementations are provided for:
  • AMQP
  • JMS
  • In memory channels
• cafe-scripted - Scripted implementation of the classic cafe sample application. Supports JavaScript, Groovy, Ruby, and Python.
• loan-broker - Simulates a simple banking application (Uses Gateway, Chain, Header Enricher, Recipient List Router, Aggregator) see Appendix A of the reference documentation for more details
• loanshark This extension to the loan broker sample shows how to exchange messages between Spring Integration applications (and other technologies) using UDP. file-split-ftp - Reads a file; splits into 3 based on contents; sends files over ftp; sends email with results.

spring-integration-mqtt With multiple Mqtt Servers for subscription

I am using Spring's spring-integration-mqtt and i can connect to a single Mqtt server and can receive messages on subscribed topics , and now i want to make application which can connect to multiple Mqtt Servers and can receive data from every connection and i want to manage it as dynamic where i can add more Mqtt servers from database or text file.

a simple bean for single Mqtt connection for subscription is as follow

@Bean
    public MessageProducer inbound() {

        MqttPahoMessageDrivenChannelAdapter adapter2 =
                new MqttPahoMessageDrivenChannelAdapter("tcp://192.168.100.1:1883","mqtt_virtual_received_sus_2",
                                                 "DATA/#", "LD/#","CONF/#","CONFIG/#");
        adapter2.setCompletionTimeout(0);
        adapter2.setConverter(new DefaultPahoMessageConverter());
        adapter2.setQos(2);

        adapter2.setOutputChannel(mqttInputChannel());
        return adapter2;

    }

above code creates a connection for the mqtt server and can receive messages and if i copy paste the same code twice for second server with different Mqtt ip address i can connect to both Mqtt Server as follows

@Bean
        public MessageProducer inbound() {

            MqttPahoMessageDrivenChannelAdapter adapter2 =
                    new MqttPahoMessageDrivenChannelAdapter("tcp://192.168.100.1:1883","mqtt_virtual_received_sus_2",
                                                     "DATA/#", "LD/#","CONF/#","CONFIG/#");
            adapter2.setCompletionTimeout(0);
            adapter2.setConverter(new DefaultPahoMessageConverter());
            adapter2.setQos(2);

            adapter2.setOutputChannel(mqttInputChannel());
            return adapter2;

        }
@Bean
        public MessageProducer inbound2() {

            MqttPahoMessageDrivenChannelAdapter adapter2 =
                    new MqttPahoMessageDrivenChannelAdapter("tcp://192.168.100.14:1883","mqtt_virtual_received_sus_1",
                                                     "DATA/#", "LD/#","CONF/#","CONFIG/#");
            adapter2.setCompletionTimeout(0);
            adapter2.setConverter(new DefaultPahoMessageConverter());
            adapter2.setQos(2);

            adapter2.setOutputChannel(mqttInputChannel());
            return adapter2;

        }

above code also works fine and i can receive message from both Mqtt Servers, but is there any way i can manage it dynamically like as follows, i change the bean's return type to list, but didn't worked:

@Bean
 public List<MqttPahoMessageDrivenChannelAdapter> getAdapter () {
     List<MqttPahoMessageDrivenChannelAdapter > logConfList=new ArrayList<MqttPahoMessageDrivenChannelAdapter>();
     MqttPahoMessageDrivenChannelAdapter adapter2 =
             new MqttPahoMessageDrivenChannelAdapter("tcp://192.168.100.1:1883","mqtt_virtual_received_sus_2",
                                              "DATA/#", "LD/#","CONF/#","CONFIG/#");
     adapter2.setCompletionTimeout(0);
     adapter2.setConverter(new DefaultPahoMessageConverter());
     adapter2.setQos(2);

     adapter2.setOutputChannel(mqttInputChannel() );

     MqttPahoMessageDrivenChannelAdapter adapter =
             new MqttPahoMessageDrivenChannelAdapter("tcp://192.168.100.14:1883","mqtt_virtual_received_sus_1",
                                              "DATA/#", "LD/#","CONF/#","CONFIG/#");
     adapter.setCompletionTimeout(0);
     adapter.setConverter(new DefaultPahoMessageConverter());
     adapter.setQos(2);

     adapter.setOutputChannel(mqttInputChannel() );
     logConfList.add(adapter);
     logConfList.add(adapter2);

     return logConfList;

 }

is there any way i can manage these beans dynamically, where i can fetch mqtt server details from text file and in a for loop or something i can manage multiple connections.

Kotlin examples?

I'm trying to set up Spring Integration in a Kotlin application, what would be the best example for that? Something like doing CRUD on Rest endpoints, parsing JSON, etc.

AMQP example runs but throws org.springframework.integration.MessageDeliveryException

When running the basic/amqp example, the following error shows up in the console:

Aggregate Processor

Hi @artembilan ,

There is a requirement for us to create a sequential pipeline where we will be getting one MessagePayload and the same payload has to go through sequence of aggregators(one after the other) and perform certain operations (e.g. updating repositories etc) and finally it has to finish.. Could you please let me know how to achieve this..i am planning to do it like below

IntegrationFlows.from("input").aggregate(
processor1-> processor1.outputProcessor(g -> new Processor1().receiver(
g.getMessages().
stream().map(message1 -> message1.getPayload()).
collect(Collectors.toList()))).correlationStrategy(m->m.getHeaders().containsKey("correlation"))
).aggregate(processor2-> processor2.outputProcessor(g -> new Processor2().receiver(
g.getMessages().
stream().map(message1 -> message1.getPayload()).
collect(Collectors.toList()))).correlationStrategy(m->m.getHeaders().containsKey("correlation"))).

         channel(output()).get();

Please let me know whether the understanding is correct

INTSAMPLES-127

with this commit, it seems that the loanshark war won't deploy without adding

<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-aspects</artifactId>
    <version>${spring.version}</version>
</dependency>

to the loanshark maven pom. also, now version inconsistencies with insight cause it to not deploy with insight.
loanshark uses spring 4.0.0.RC1 spring, but the spring insight plugins depends on spring framework version 3.2.1.RELEASE and spring.integration.version 2.2.1.RELEASE.
Is it possible that the insight war dependencies are getting into the classloader for loanshark?
I see the following error occur when I deploy and start loan shark:

I think that the problem is that TopicCreator.start() is getting called too late. I'm a beginner when it comes to Spring, but I think that TopicCreator should implement InitializingBean instead of SmartLifecycle. I made the respective change on a branch (see Application.java). It seems to work (I changed the value of kafka.topic several times and I didn't get any exceptions), but this might be pure luck.

exceptions for the mail basic sample

Hi,
Any help would be appreciated.
I'm receiving exceptions with both the IMAP and POP implementations.
The POP3/IMAP access is enabled in my google account.
Here is the status as stated in gmail settings for IMAP: Status: IMAP is enabled.
Here is the status as stated in gmail settings for POP3: 1. Status: POP is enabled for all mail that has arrived since....

The IMAP fails with this exception:

message is not deleted from the queue post read

This is not really an issue with RabbitMq but more of a help required in order to implement a SimpleMessageListenerContainer in a manner that it removes the message, un-transactionally, as soon read by the message receiver.

But in my case, irrespective of successful or unsuccessful transactions, the message remains in the queue, causing its repeated processing.

Below is the code snippet of my container bean configuration, it will be of great help if someone can point out the mistake in here:-

@Bean
SimpleMessageListenerContainer container(ConnectionFactory connectionFactory, MessageListenerAdapter listenerAdapter) {
        SimpleMessageListenerContainer container = new SimpleMessageListenerContainer();
        container.setAcknowledgeMode(NONE);
        container.setConnectionFactory(connectionFactory);
        container.setQueueNames(queueName);
        container.setMessageListener(listenerAdapter);
        return container;
    }

I just got branch 4.3.x, when I run StatelessRetryDemo, got the following error

Can't build the current master

Several Dependencies are not in "normal" repos, missing declaration of custom repos in main pom.

Had to include the http://repo.springsource.org/libs-snapshot/ repository to get rid of the following missing dependencies:

Could not resolve dependencies for project org.springframework.integration.samples:jpa:jar:2.2.0.BUILD-SNAPSHOT: Could not find artifact org.eclipse.persistence:org.eclipse.persistence.jpa:jar:2.3.2

Could not resolve dependencies for project org.springframework.integration.samples:xquery:jar:1.0.0.BUILD-SNAPSHOT: The following artifacts could not be resolved: net.xqj.sedna:sedna-xqj:jar:1.0.0, com.xqj2:xqj2:jar:0.1.0: Could not find artifact net.xqj.sedna:sedna-xqj:jar:1.0.0

integration-http inbound with no Content-Type header

Hello,
I imported spring-int-basic-http example and ran the request using Fiddler. Here is my URL and request header:
URL: http://localhost:8080/http-4.1.0.BUILD-SNAPSHOT/receiveGateway
Method: Post
HTTP Headers: User-Agent: Fiddler
Host: localhost:8080
Content-Length: 93

The response is blank. If I add a request header:
Content-Type: text/plain
I get response from server. Please help me with this. I have a client application which is hitting the URL without passing Content-Type and hence I am unable to read the request body.

amqp module missing release/snapshot repos

amqp examples won't build run and the snapshot/release repos don't exist in the pom.xml

requires:

<repository>
        <id>repository.springframework.maven.milestone</id>
        <name>Spring Framework Maven Milestone Repository</name>
        <url>http://maven.springframework.org/milestone</url>
    </repository>
    <repository>
        <id>repository.springframework.maven.snapshot</id>
        <name>Spring Framework Maven Snapshot Repository</name>
        <url>http://maven.springframework.org/snapshot</url>
    </repository>

I can't run this examples

I notice that this dependency doesn't work anymore

    <dependency>
      <groupId>org.springframework.integration</groupId>
      <artifactId>spring-integration-sftp</artifactId>
      <version>5.0.0.BUILD-SNAPSHOT</version>
      <scope>compile</scope>
    </dependency>

I have to replace this this one

    <dependency>
      <groupId>org.springframework.integration</groupId>
      <artifactId>spring-integration-sftp</artifactId>
      <version>5.0.0.M2</version>
      <scope>compile</scope>
    </dependency>

Then I got a class not found exception because no dependencies for spring-core

    <dependency>
      <groupId>org.springframework.integration</groupId>
      <artifactId>spring-integration-core</artifactId>
      <version>4.3.7.RELEASE</version>
    </dependency>

But when I tried to run the example SftpOutboundTransferSample I got this error :

kafka: set message key dynamically

Regarding the kafka sample code, currently you can only have one message key, which you set it in application.properties. After running the application there is no way to change it.

Is there a way to set the message key dynamically, before sending the message?

Is the FTP example, actually working?

when I run it I'm getting this:

org.springframework.messaging.MessagingException:` Failed to invoke handler; nested exception is org.springframework.messaging.MessagingException: Failed to execute on session; nested exception is java.lang.IllegalStateException: failed to create FTPClient, failedMessage=GenericMessage [payload=target\toSend\a.txt, headers={timestamp=1489108163505, id=84218d92-8f62-13aa-587f-3cf1e9768a5b}]

Also, what does it means? spring-integration-samples/basic/ftp/src/test/java/org/springframework/integration/samples/ftp/support/TestUserManager.java

It says don't use hardcoded Port. But, how to do that?

Are these groovy scripts debuggable?

Is there any way to debug groovy scripts written in xml?

SPRING user password?

A security filter has been added and that's great. The password in the user security properties is encrypted and therefore, one cannot access the app without cracking the code. Please add the explicit clear-text credentials in the readme.

This is it (I think)
SPRING / spring

Thanks!

STOMP Chat sample is out of date

There is an old reactor.tuple.Tuple usage in the XML config.

1. The Reactor isn't required dependency for SI since 4.2 (at least until 5.0)
2. In the Reactor 2.0.x the Tuple has been moved to the new reactor.fn.tuple package.

Getting web sockets to work on spring mvc

I have a spring mvc project with the latest version of spring framework but i just cant seem to have the web sockets functionality to work.

I have this as my web sockets config

package com.authority.configuration;

import org.springframework.context.annotation.Configuration;
import org.springframework.messaging.simp.config.ChannelRegistration;
import org.springframework.messaging.simp.config.MessageBrokerRegistry;
import org.springframework.web.socket.config.annotation.EnableWebSocketMessageBroker;
import org.springframework.web.socket.config.annotation.StompEndpointRegistry;
import org.springframework.web.socket.config.annotation.AbstractWebSocketMessageBrokerConfigurer;


@Configuration
@EnableWebSocketMessageBroker
public class WebSocketsConfiguration extends AbstractWebSocketMessageBrokerConfigurer {

    @Override
    public void registerStompEndpoints(final StompEndpointRegistry registry) {
        registry.addEndpoint("/random").withSockJS();
    }

    @Override
    public void configureClientInboundChannel(
        final ChannelRegistration registration) {
    }

    @Override
    public void configureClientOutboundChannel(
        final ChannelRegistration registration) {
    }

    @Override
    public void configureMessageBroker(final MessageBrokerRegistry registry) {
    }

}

I have this security config

package com.authority.configuration;

import org.springframework.context.annotation.Configuration;
import org.springframework.security.config.annotation.web.messaging.MessageSecurityMetadataSourceRegistry;
import org.springframework.security.config.annotation.web.socket.AbstractSecurityWebSocketMessageBrokerConfigurer;

@Configuration

        return true;
    }

    @Override
    protected void configureInbound(MessageSecurityMetadataSourceRegistry messages) {
        messages.anyMessage().permitAll();
    }
}

but i still get this error when i run

No XML example of jdbc outbound gateway

Is there an no xml example of the basic jdbc sample available? Am particularly interested in converting the following part using annotations.

                                request-channel="createPersonRequestChannel"
                                reply-channel="createPersonReplyChannel"
                                update="insert into Person (name,gender,dateOfBirth) 
                                    values
                                    (:name,:gender,:dateOfBirth)"
                                query="select * from Person where id = :id"

                            row-mapper="personResultMapper"
                                keys-generated="true"/>

xsi:SchemaLocation is not match pom.xml dependency's version.

For example in https://github.com/spring-projects/spring-integration-samples/blob/master/basic/file/src/main/resources/META-INF/spring/integration/fileCopyDemo-binary.xml schemaLocation shows http://www.springframework.org/schema/integration/spring-integration.xsd and http://www.springframework.org/schema/integration/file/spring-integration-file.xsd schema. But if you see into these files, you find an older version than 3.0.

In pom.xml:
<spring.integration.version>3.0.0.RELEASE</spring.integration.version>

When I use an IDE (NetBeans) the XSD xsd:documentation element shown as documentation, but not for version 3.0.

why i can not download the jars in pom.xml

• spring-integration-kafka
• spring-integration-core
• spring-kafka
• spring-kafka-test
  these all can not download, can anybody tell me why ?

Declaring control bus in java config

Hi,
How can I configure a control bus in a java configuration file ? All the examples and docs I see show how to declare it in xml, but I don't know which class gets instantiated.

Thank you.

spring-kafka without spring-boot

is it possible to use spring-kafka or spring-integration-kafka without using spring-boot.
I have implemented producer without spring-boot,
but somehow not able to find consumer alternative i.e. @KafkaListener (spring-kafka)
Any help on this is useful.

Is there any existing repo which has this implemented?
Also, are there any disadvantages of using spring instead of spring-boot.

In our use case, we want to use Kafka as a library and hence wants to use spring.

Hi Team,

here is my piece of code,

        System.out.println("***started Polling***");
        faxFolder = Paths.get(folderPath);

}

The above Code is running perfectly with Tomcat 7 & jdk 1.8

but when I use jdk 1.7 , The Server is getting hanged while trying to initialize
Spring FrameworkServlet 'appDispatcher' .

Dec 28, 2015 4:20:14 PM org.apache.catalina.core.ApplicationContext log

Is there anything to do with jdk Versions ?

Can't compile/run in Eclipse

Hey Guys, thanks for making this samples repository available to those of us learning Spring Integration.

Getting few issue as I import project into Eclipse.
Hope I can get a head start on one of my projects with this sample and am missing something simple and easy to fix in my configuration. (I'm able to build/run other projects from this repo and think my env. more-or-less stable at this juncture)

Missing StringConversionService

The service class is missing the StringConversionService. I found it in another example in the repo but I'm assuming you would like this code to be self contained.

travel example spring version/yahoo service

The "travel" example declares a dependency on spring-web 3.1.0, which brings in spring-core 3.1.0, which conflicts with 3.0.7 and causes bean loading errors.

Also the yahoo traffic service appears to be dead.

I am newer,who can help me to solve this problem?

The base/testing-examples package。

Cafe-dsl sample not working

It seems that after the route call the flow does not go back to the main flow (.defaultOutputToParentFlow() seems not to be working) and the commands after the route are never being executed.

Are spring web sockets a single http connection per subscription?

I have a web page that makes use of spring web sockets. I have one subscription and that does work as expected. However, i need the web page to subscribe to more than 100 objects. let me explain what the 100 objects are.

I have a registered user who must login and receive realtime data from 100+ Gps devices and i need to display the location of the devices to the logged in user.

With over 5000 users of the app, i can theorize that at any one time, my app will need to handle 500,000 concurrent web socket connections.

Does spring create a new http connection for every subscription?.

Can i make a web page subscribe to those many objects without running into problems?.

Can spring handle those many concurrent web socket connections?
