How to use

1. Copy the files RabbitMQConfig.java, RabbitMqDeclarator.java, and RabbitMqPublisher.java into a folder within your service. Ensure they are in the same Java package.

2. Add the following dependency to your pom.xml. For more detailed steps, refer to the library's README: https://github.com/Podzilla/mq-utils-lib/blob/main/README.md

   <dependency>
       <groupId>com.github.Podzilla</groupId>
       <artifactId>mq-utils-lib</artifactId>
       <version>main-SNAPSHOT</version>
   </dependency>

3. In the RabbitMQConfig.java file, add your event definitions to the PRODUCE_EVENTS and CONSUME_EVENTS sets.

4. It is mandatory to have spring.application.name defined in your application.properties file.

5. To listen to a specific event, use the @RabbitListener annotation as shown below:

   @RabbitListener(
       queues = "#{ T(com.podzilla.mq.utils.RabbitMqNaming).getQueueName(T(com.podzilla.mq.EventsConstants).ORDER_PLACED, T(com.example.demo.RabbitMQConfig).getServiceName()) }"
   )
   public void listenToOrderPlaced(YourEventType eventPayload) {
       // Your message processing logic here
   }

   Note: Change com.example.demo to the actual package name where you placed the RabbitMQConfig.java file.
