rocketmq发送有序消息笔记

1. 添加依赖

   <dependency>
       <groupId>com.alibaba.cloud</groupId>
       <artifactId>spring-cloud-starter-stream-rocketmq</artifactId>
   </dependency>
   

2. 添加注解

   @EnableBinding({Source.class,Sink.class})
   @SpringBootApplication
   public class SequenceMessageApplication {
       public static void main(String[] args) {
           SpringApplication.run(SequenceMessageApplication.class, args) ;
       }
   }
   

3. 添加配置

   server.port=8081
   # spring cloud stream config
   spring.cloud.stream.rocketmq.binder.name-server=192.168.221.128:9876
   # 生产者配置
   spring.cloud.stream.bindings.output.destination=TopicTest
   spring.cloud.stream.rocketmq.bindings.output.producer.group-demo-group
   # 设置同步消息
   spring.cloud.stream.rocketmq.bindings.output.producer.sync=true
   ##########
   # 消费者配置
   spring.cloud.stream.bindings.input.destination=TopicTest
   spring.cloud.stream.bindings.input.group=test-group1
   # 指定顺序消费
   spring.cloud.stream.rocketmq.bindings.input.consumer.orderly=true
   

4. 生产消息

    @Autowired
   private Source source;
   
   @GetMapping("/orderly")
   public String orderly() {
       List<String> typeList = Arrays.asList("创建","支付","退款") ;
       for (String type: typeList){
           MessageBuilder builder = MessageBuilder.withPayload(type)
                   .setHeader(BinderHeaders.PARTITION_HEADER,0);
           Message message = builder.build() ;
           source.output().send(message) ;
       }
       return "OK";
   }
   

5. 消费消息

@StreamListener(Sink.INPUT)
public void receive(String receiveMsg){
    log.info("TopicTest receive : {}, receiveTime = {}", receiveMsg, System.currentTimeMillis());
}
