配置好rabbitmq服务器

![70][]

编写消息发送者

添加依赖pom.xml

<dependency>
       <groupId>org.springframework.cloud</groupId>
       <artifactId>spring-cloud-starter-stream-rabbit</artifactId>
    </dependency>

修改配置application.yml

server:
      port: 8088
    
    spring:
      application:
        name: tms-send
      rabbitmq:
        host: 192.168.1.109
        port: 5672
        username: rabbit-username
        password: rabbit-password

启动类 TmsSendApplication.java

@SpringBootApplication
    @EnableEurekaClient
    @EnableBinding(RabbitSendService.class)
    public class TmsSendApplication {
       public static void main(String[] args) {
          SpringApplication.run(TmsSendApplication.class, args);
       }
    }

编写发送接口

public interface RabbitSendService {
        @Output(value = "myInput")
        SubscribableChannel sendMsg() throws Exception;
    }

编写controller

@RestController
    public class TestController {
    
        @Autowired
        private RabbitSendService rabbitService;
    
        @GetMapping(value = "/sendMsg")
        public String sendMsg() throws Exception {
            Message message = MessageBuilder.withPayload("Hello World".getBytes()).build();
            rabbitService.sendMsg().send(message);
            return "success";
        }
    }

三、编写消息接受者

添加依赖pom.xml

<dependency>
       <groupId>org.springframework.cloud</groupId>
       <artifactId>spring-cloud-starter-stream-rabbit</artifactId>
    </dependency>

修改配置application.yml

启动类 TmsSendApplication.java

@SpringBootApplication
    @EnableEurekaClient
    @EnableBinding(RabbitReceiveService.class)
    public class TmsReceiveApplication {
       public static void main(String[] args) {
          SpringApplication.run(TmsReceiveApplication.class, args);
       }
    }

编写消息监听

@Component
    public class RabbitReceiveListener {
        @StreamListener(value = "myInput")
        public void onReceive(byte[] msg){
            System.out.println(new String(msg));
        }
    }

编写消息接口

public interface RabbitReceiveService {
        @Input(value = "myInput")
        SubscribableChannel inputMsg() throws Exception;
    }

四、启动eureka注册中心，启动消息发送者与消息接收者

访问接口 http://127.0.0.1:8088/sendMsg

![70 1][]

消息接收者的的监听器获取到的消息

Hello World
