1. Create a New Maven Project(Create Simple Project)
2.Add the following dependency in the
pom.xml
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>1.5.4.RELEASE</version>
<relativePath/> <!-- lookup parent from repository -->
</parent>
<properties>
<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
<project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>
<java.version>1.8</java.version>
</properties>
<dependencies>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-amqp</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-test</artifactId>
<scope>test</scope>
</dependency>
</dependencies>
<build>
<plugins>
<plugin>

3.Add the following code to the application.properties
spring.rabbitmq.host=127.0.0.1
spring.rabbitmq.port=5672
spring.rabbitmq.username=guest
spring.rabbitmq.password=guest
jsa.rabbitmq.exchange=jsa.direct
jsa.rabbitmq.routingkey=jsa.routingkey
jsa.rabbitmq.queue=jsa.queue
4. Create a
Producer class
@Component
public class Producer {
@Autowired
private AmqpTemplate amqpTemplate;
@Value("${jsa.rabbitmq.exchange}")
private String exchange;
@Value("${jsa.rabbitmq.routingkey}")
private String routingKey;
public void produceMsg(String msg)
{
amqpTemplate.convertAndSend(exchange,routingKey,msg);
System.out.println("Send msg"+msg);
}
}
5.Create a mockup rest service to send the message
@RestController
public class WebController {
@Autowired
Producer producer;
@RequestMapping("/send")
public String sendMsg(@RequestParam("msg")String msg)
{
producer.produceMsg(msg);
return "Done";
}
}
6. Create a Consumer to consume the message
@Component
public class Consumer {
@RabbitListener(queues="${jsa.rabbitmq.queue}")
public void receivedMessage(String msg)
{
System.out.println("Recieved Msg"+msg);
}
}
