Spring Boot整合RocketMQ主要涉及到生产者和消费者的配置。以下是一个简单的例子：
- 添加依赖到
pom.xml：
<dependencies>
<!-- RocketMQ Spring Boot Starter -->
<dependency>
<groupId>org.apache.rocketmq</groupId>
<artifactId>rocketmq-spring-boot-starter</artifactId>
<version>2.2.1</version>
</dependency>
</dependencies>
- 在
application.properties或application.yml中配置RocketMQ参数：
# RocketMQ Config
spring.rocketmq.name-server=127.0.0.1:9876
spring.rocketmq.producer.group=my-group
- 创建一个消息生产者：
import org.apache.rocketmq.spring.core.RocketMQTemplate;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;
@RestController
public class ProducerController {
@Autowired
private RocketMQTemplate rocketMQTemplate;
@GetMapping("/sendMessage")
public String sendMessage() {
rocketMQTemplate.convertAndSend("topic:test", "Hello, RocketMQ!");
return "Message sent successfully!";
}
}
- 创建一个消息消费者：
import org.apache.rocketmq.spring.annotation.RocketMQMessageListener;
import org.apache.rocketmq.spring.core.RocketMQListener;
import org.springframework.stereotype.Component;
@Component
@RocketMQMessageListener(topic = "topic:test", consumerGroup = "my-consumer_test")
public class Consumer implements RocketMQListener<String> {
@Override
public void onMessage(String message) {
System.out.println("Received message: " + message);
}
}
确保你的RocketMQ服务器正在运行并且配置正确。当你访问/sendMessage端点时，生产者将发送消息到名为topic:test的主题，消费者将监听这个主题并打印接收到的消息。
