Demo application to go with Blog on spring.io

microservices-demo

Demo application to go with my Microservices Blog on the spring.io website. WARNING: Only maven build has been updated. Gradle build still to be done.

Clone it and either load into your favorite IDE or use maven/gradle directly.

Note for gradle users: to make the intructions below build-tool independent, the gradle build copies its artifacts from build/libs to target.

Versions

Current version (Jan 2021) v2.1.1 corresponds to Spring Boot 2.4.2 and Spring Cloud 2020.0.0 release train.

Previous versions have been tagged and can be accessed using the Branch button above or using git checkout <version> - for example git checkout v1.2.0.

Tagged versions are:

• v2.1.1 - Spring Boot 2.4.2, Spring Cloud release-train 2020.0.0 and overdue update to Bootstrap 4 (Jan 2021)
• v2.1.0 - Spring Boot 2.4.2 and Spring Cloud release-train 2020.0.0 (Jan 2021)
• v2.0.0 - Spring Boot 2.0 and Spring Cloud release-train Finchley (Feb 2020)
• v1.2.0 corresponds to Spring Boot 1.5 and Spring Cloud release-train Edgeware (Apr 2018)
• v1.1.0 corresponds to Spring Cloud release-train Brixton (Jan 2018)
• v1.0.0 corresponds to Spring Cloud release-train Angel.SR6 (May 2016)

If running with Java 11 or later, you need to upgrade the build to include additional dependencies. Refer to #32 for details.

Using an IDE

You can run the system in your IDE by running the three server classes in order: RegistrationService, AccountsService and WebService. Each is a Spring Boot application using embedded Tomcat. If using Spring Tools use Run As ... Spring Boot App otherwise just run each as a Java application - each has a static main() entry point.

As discussed in the Blog, open the Eureka dashboard http://localhost:1111 in your browser to see that the ACCOUNTS-SERVICE and WEB-SERVICE applications have registered. Next open the Demo Home Page http://localhost:3333 in and click one of the demo links.

The localhost:3333 web-site is being handled by a Spring MVC Controller in the WebService application, but you should also see logging output from AccountsService showing requests for Account data.

Command Line

You may find it easier to view the different applications by running them from a command line since you can place the three windows side-by-side and watch their log output

For convenience we are building a 'fat' executble jar whose start-class (main method entry-point) is defined to be in the class io.pivotal.microservices.services.Main. This application expects a single command-line argument that tells it to run as any of our three servers.

java -jar target/microservices-demo-2.0.0.RELEASE.jar registration|accounts|web

Procedure

To run the microservices system from the command-line, open three CMD windows (Windows) or three Terminal windows (MacOS, Linux) and arrange so you can view them conveniently.

1. In each window, change to the directory where you cloned the demo.
2. In the first window, build the application using either ./mvnw clean package or ./gradlew clean assemble. Either way the generated file will be target/microservices-demo-2.0.0.RELEASE.jar (even if you used gradle).
3. In the same window run: java -jar target/microservices-demo-2.0.0.RELEASE.jar registration
4. Switch to the second window and run: java -jar target/microservices-demo-2.0.0.RELEASE.jar accounts
5. In the third window run: java -jar target/microservices-demo-2.0.0.RELEASE.jar web
6. In your favorite browser open the same two links: http://localhost:1111 and http://localhost:3333

You should see servers being registered in the log output of the first (registration) window. As you interact wiht the Web application, you should logging in the both the second and third windows.

For a list of valid accounts refer to the data.sql that is used by the Account Service to set them up.

1. In a new window, run up a second account-server using HTTP port 2223:
   • java -jar target/microservices-demo-2.0.0.RELEASE.jar accounts 2223
2. Allow it to register itself
3. Kill the first account-server and see the web-server switch to using the new account-server - no loss of service.

Using Docker

This application can also be run using 3 docker containers. See here.

microservices-demo's Issues

Unable to run from jar, but able to run from IDE

Encountered "Error creating bean with name 'entityManagerFactory' defined in class path resource " while launching java -jar microservices-demo-1.1.0.RELEASE.jar registration. This error however is not triggered while launching from IDE.

Related to spring-projects/spring-boot#6635 and is fixable by upgrading spring boot version to 1.4.1

Doubts with -- registration.server.hostname

Hi Paul! I'm here again.
I don't understand how the '--registration.server.hostname' parameter works when we run a container. I have been reading the parameters of the docker run command with docker run --help, but I don't understand the creation of this parameter.
I know that system environment variables exist, but that they are passed by parameter using: '--env Key-Value'. Isn't --registration.server.hostname a system environment variable?
I know that the value you enter in that parameter is replaced in the '.properties' file of each eureka client and that serves to indicate to the client where the registration server is, but I don't know how Docker understands that parameter because what's normal and what it says in the documentation is passing it as an environment variable.
I executed the order: 'docker run --name accounts --hostname accounts --network accounts-net -p 2222:2222 paulc4/microservice java -jar app.jar accounts --env registration.server.hostname= but it doesn't work, so I assume it's not the same.
Thanks!

Non existant file in the README.md file

The README.md file reads:
java -jar target/microservice-demo-0.0.1-SNAPSHOT.jar accounts 2223

But this jar file does not exist.

It should read:
java -jar target/microservice-demo-1.1.0.RELEASE.jar accounts 2223

500 internal server error

Hi,

I'm running 1 registration, 1 web and 2 accounts, but when I close one of the accounts microservice sometimes I get the following error when I try a /accounts/123456789 :

I think it tries to send a request to the closed microservice, but it's already unregistered, it doesn't even show in the eureka's dashboard.

Thank you.

Need help to run this project

In Readme, they mentioned to kill first account server and run the second one, how to kill the first instance server.?
Can we run more than one instance of a same service.If so,how to do it?Will the eureka dashboard displays how many instances of same service are running.
Do we need to change any port settings in the code?I have no idea how to do that. Please explain the whole project how it is running clearly.
Please reply me as soon as possible.
Appreciate your help.

Towards MySQL production database

Hi everyone,
i have found this repository from spring.io web site.
I'm trying to use a MySQL db with the code within this repository.

When i launch the maven command clean and package i receive the Build Success message, but if i launch the registration application, as the readme file describes, i receive the following java exception:

I use osx el capitan 10.11.3 with java 1.8 sdk and maven 3.3.9.

Is there anyone which could help me?

Can't see embedded datasource initializing

I triedt this demo, It works great. All 3 services starts up, but Account service does not configure/start/initialize the embedded db (H2 or hsqldb?). Why? Also, it does not map any account controller urls like /accounts/{accountNumber} ???????

Does not work with Java 11

As written this code does not work under Java 11. However it can be fixed by adding some dependencies to the pom file. I added the following dependencies and it seems to be working for me fine now.

        <dependency>
            <groupId>com.sun.xml.bind</groupId>
            <artifactId>jaxb-core</artifactId>
            <version>2.3.0.1</version>
        </dependency>

        <dependency>
            <groupId>com.sun.xml.bind</groupId>
            <artifactId>jaxb-impl</artifactId>
            <version>2.3.1</version>
        </dependency>

        <dependency>

            <artifactId>activation</artifactId>
            <version>1.1.1</version>
        </dependency>

        <dependency>
            <groupId>javax.xml.bind</groupId>
            <artifactId>jaxb-api</artifactId>
            <version>2.3.0</version>
        </dependency>

        <dependency>
            <groupId>org.javassist</groupId>
            <artifactId>javassist</artifactId>
            <version>3.25.0-GA</version>
        </dependency>

I hope this helps anyone else trying to get this running with Java 11

Blog link in README.md needs to be updated

It looks like the README.md has a link to your blog article that isn't quite right:

Demo application to go with my Microservices Blog on the spring.io website.

Should this link point to:

Demo application to go with my Microservices Blog on the spring.io website.

...?

Doubts with WebServer

Hi @paulc4,
I'm a computer science student who's about to finish my career. I'm working on a project that involves making a website through microservices and to inform myself I've been analyzing your code.
My architecture would be based on four microservices: web-service, products-service, cart-service, and payment-service.This is where my doubt comes in.
You in the project have included the WebAccountsService and WebAccountsController classes to manage the account-service information. What would happen when I want to include controllers and services to handle information from the rest of the microservices? Should I create more classes of the style 'WebProductsController"? I don't think because there would be a project with many classes.
I also don't know if it would be good practice to create two classes, WebController and WebService, to handle all the information (WebService would contain all microservices access URLs).
I've searched the internet for information but I know there are several ways to approach web UI management in microservices.
Thanks! :)

Needs build instructions

I'm trying this demo on macOS. But you need some command-line build instructions. What gradle command do I invoke? I tried gradle jar, and that did something, but the results are in build/libs, not target.

Anyway, trying to run that jar, I get:

$ java -jar build/libs/microservices-demo-1.1.0.RELEASE.jar registration
no main manifest attribute, in build/libs/microservices-demo-1.1.0.RELEASE.jar

gradle build works better, but I get:

$ java -jar build/libs/microservices-demo-1.1.0.RELEASE.jar registration

405 METHOD_NOT_ALLOWED

Hi Paul, I applied your demo and it worked great but I am getting 405 METHOD_NOT_ALLOWED exception when I am trying to send a POST request. I changed the code like below:

In WebAccountsController class:

FROM

@RequestMapping(value = "/accounts/search", method = RequestMethod.GET)
    public String searchForm(Model model) {
        model.addAttribute("searchCriteria", new SearchCriteria());
        return "accountSearch";
    }

TO

    @RequestMapping(value = "/accounts/search", method = RequestMethod.POST)
    @ResponseStatus(value=HttpStatus.OK)
    @ResponseBody
    public String searchForm(@ModelAttribute SearchCriteria searchCriteria, Model model) {
        model.addAttribute("searchCriteria", searchCriteria);
        return "accountSearch";
    }

In WebAccountsService class:

FROM

    public Account findByNumber(String accountNumber) {

        logger.info("findByNumber() invoked: for " + accountNumber);
        return restTemplate.getForObject(serviceUrl + "/accounts/{number}",
                Account.class, accountNumber);
    }   

TO

    public Account findByNumber(String accountNumber) {

        logger.info("findByNumber() invoked: for " + accountNumber);
        return restTemplate.postForObject(serviceUrl + "/accounts/",accountNumber,Account.class);
    }

and in accountSearch.html file:

FROM

    <form action="#" th:object="${searchCriteria}" method="GET"
        th:action="@{/accounts/dosearch}" class="form-horizontal">

TO

    <form action="#" th:object="${searchCriteria}" method="POST" 
        th:action="@{/accounts/dosearch}" class="form-horizontal">

What else should I change? Could you please help me?

why account service is displaying as one in eureka console..?

Hi Paul ,

It was a very nice article and everything worked as expected but i have a question related to eureka console that it is displaying only account service count as 1 instead of 2 since i am running two instances of account service in my local machine . Is there any reason behind this ?

Thanks,
Akhil.
