引入依赖
这里我们使用rocketmq-spring-boot-starter来访问rocketmq。
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
<dependency>
<groupId>org.apache.rocketmq</groupId>
<artifactId>rocketmq-spring-boot-starter</artifactId>
<version>2.0.4</version>
</dependency>
配置文件中需要配置rocketmq的nameserver等信息：
server:
port: 8090
rocketmq:
name-server: node1:9876
producer:
group: myGroupName
测试发送消费消息
@RestController
@Slf4j
public class HelloController {
@Autowired
private RocketMQTemplate rocketMQTemplate;
@GetMapping("/hello")
public String hello() {
// 生产者
rocketMQTemplate.convertAndSend("TopicTest", "Hello, World!");
rocketMQTemplate.send("TopicTest", MessageBuilder.withPayload("Hello, World! I'm from spring message").build());
return "Welcome to springboot2 world ~";
}
}
//消费者
@Slf4j
@Service
@RocketMQMessageListener(topic = "TopicTest", consumerGroup = "my-consumer_TopicTest")
public class MyConsumer implements RocketMQListener<String> {
public void onMessage(String message) {
log.info("received message: " + message);
}
}
//启动类
@SpringBootApplication
public class Application {
public static void main(String[] args) {
SpringApplication.run(Application.class, args);
}
}
启动服务，调用http://127.0.0.1:8090/hello来发送消息。
可以看到在控制台输出：
2020-01-21 11:54:39.392 INFO 1436 --- [MessageThread_1] com.example.service.MyConsumer : received message: Hello, World!
2020-01-21 11:54:39.410 INFO 1436 --- [MessageThread_2] com.example.service.MyConsumer : received message: Hello, World! I'm from spring message
然后在rocketmq的控制台也同样定义消息，可以看到数据更加详细信息：
[root@node1 bin]# ./tools.sh org.apache.rocketmq.example.quickstart.Consumer
11:27:15.018 [main] DEBUG i.n.u.i.l.InternalLoggerFactory - Using SLF4J as the default logging framework
