CLIENTS MICROSERVICE - Event Driven with SpringBoot and RabbitMQ Producer

This is a simple example of microservice, we are using the event driven architecture.

For more details of consumer see the example here: https://github.com/felipegirotti/spring-boot-event-driven-consumer

API

We expose a simple CRUD HTTP API.

• POST /api/v1/client Body:

  {   
      "name": "Client Example"      
  }

• GET /api/v1/client/{id}

• GET /api/v1/clients?page=0

• PUT /api/v1/client/{id} Body:

  {   
       "name": "Client Example UP"
  }

• DELETE /api/v1/client/{id}

From POST/PUT we emit an event with routing key clients.client.save, for delete, we are using the same exchange and queue but the routing key is different clients.client.delete

Run locally

We are using env variables to setup the database properties and others configs
See the .env.example and export your variables.
e.g:

export $(cat .env.example | xargs)
mvn spring-boot:run

Docker compose

There a few dependencies, Mysql and RabbitMQ, those are configured into the docker-compose.yaml.
Run docker-compose up -d

Build a image with docker

For build a image you should first create a jar file with this command below:

mvn clean package

After that just build the image (pay attention on the file of jar):

docker build . -t {{REPLACE_YOUR_DOCKER_HUB_NAME}}/client-java-example --build-arg JAR_FILE=target/client-0.0.1-SNAPSHOT.jar

And push the image to DockerHub

docker push {{REPLACE_YOUR_DOCKER_HUB_NAME}}/client-java-example
