proteus-springboot-example

A simple example of integrating Spring Boot and Netifi Proteus to create request/reply interactions with microservices.

Prerequisites

This example requires the following prerequisites:

Protocol Buffers Compiler

You can download the compiler from here: https://github.com/google/protobuf/releases

OR

If you are on a mac using homebrew you can install it with the following command:
```
 $ brew install protobuf
```

A running instance of the Proteus Broker You can pull the latest Proteus Broker from DockerHub using the following command:

     $ docker pull netifi/proteus

Start the Proteus Broker by running the following command:

     $ docker run -p 8001:8001 -p 7001:7001 -e BROKER_SERVER_OPTS='-Dnetifi.authentication.0.accessKey=3006839580103245170 -Dnetifi.authentication.0.accessToken=SkOlZxqQcTboZE3fni4OVXVC0e0=' netifi/proteus

Running the Example

Run the following Gradle commands in separate terminals to see the example:

Start the helloworld-service
```
 $ ./gradlew :helloworld-service:run
```
Start the helloworld-client
```
 $ ./gradlew :helloworld-client:run -PappArgs="['Foo']"
```
You will see the following in the helloworld-client terminal when successful:
```
 Received from helloworld-service: Hello, Foo!
```
You will see the following in the helloworld-service terminal when successful:
```
 Received Hello Request for: Foo
```

Note: The order in which you run the commands does not matter as Proteus clients/services are aware of their environment and will only start sending data when their dependent services are available.

Now start another helloworld-service and send some more requests with helloworld-client. You will notice that requests are not being automatically load balanced across the instances of helloworld-service without any code or configuration change.
