RocketMQ和Spring Boot的整合可以通过使用RocketMQ的Spring Boot Starter来实现。下面是整合的步骤:
1. 引入RocketMQ的Spring Boot Starter依赖。在你的Spring Boot项目的`pom.xml`文件中添加以下依赖:
```xml
<dependency>
<groupId>org.apache.rocketmq</groupId>
<artifactId>rocketmq-spring-boot-starter</artifactId>
<version>2.1.1</version>
</dependency>
```
2. 配置RocketMQ的相关属性。可以在`application.properties`(或者`application.yml`)文件中配置RocketMQ的相关属性,例如:
```properties
# NameServer的地址,多个地址使用逗号分隔
rocketmq.name-server=127.0.0.1:9876
# 消费者组名
rocketmq.consumer.group=my-consumer-group
# 生产者组名
rocketmq.producer.group=my-producer-group
```
3. 创建RocketMQ的生产者。使用`@EnableRocketMQ`注解开启RocketMQ支持,并创建一个生产者实例。例如:
```java
import org.apache.rocketmq.spring.core.RocketMQTemplate;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;
@Component
public class MyProducer {
@Autowired
private RocketMQTemplate rocketMQTemplate;
public void sendMessage(String topic, String message) {
rocketMQTemplate.convertAndSend(topic, message);
}
}
```
4. 创建RocketMQ的消费者。使用`@RocketMQMessageListener`注解创建一个消费者实例,并指定要监听的主题和消费逻辑。例如:
```java
import org.apache.rocketmq.spring.annotation.RocketMQMessageListener;
import org.apache.rocketmq.spring.core.RocketMQListener;
import org.springframework.stereotype.Component;
@Component
@RocketMQMessageListener(topic = "my-topic", consumerGroup = "my-consumer-group")
public class MyConsumer implements RocketMQListener<String> {
@Override
public void onMessage(String message) {
System.out.println("Received message: " + message);
// 处理消息的业务逻辑
}
}
```
5. 使用RocketMQ的生产者发送消息。在需要发送消息的地方注入生产者实例,并调用`sendMessage`方法发送消息。例如:
```java
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.RestController;
@RestController
public class MyC
