Spring Boot 集成 RabbitMQ 时,若想利用消息交换机 (Exchange) 的确认模式(Confirm Exchange),并设置异步回调处理消息确认,通常需要在配置文件中添加特定设置,并创建一个消费者类来处理回调。以下是基本步骤:
1. **启用RabbitMQ支持**:首先,在`application.properties`或`application.yml`文件中添加RabbitMQ的连接信息:
```properties
spring.rabbitmq.host=localhost
spring.rabbitmq.port=5672
spring.rabbitmq.username=guest
spring.rabbitmq.password=guest
```
2. **配置Exchange和Queue**:确认交换机 (`confirm-exchange`) 和队列 (`confirm-queue`) 可能需要分别配置:
```yaml
spring.rabbitmq.exchanges:
confirm-exchange:
type: direct
durable: true
autoDelete: false
internal: false
arguments:
x-dead-letter-exchange: dead-letter-exchange # 死信交换机
spring.rabbitmq.queues:
confirm-queue:
bindings:
- exchange: confirm-exchange
routingKey: confirm.# # 匹配所有路由键
queue: confirm-queue
arguments:
x-message-ttl: 30000 # 30秒超时时间
```
3. **配置消费者**:创建一个消费确认消息的消费者类,例如 `ConfirmMessageConsumer`,继承自 `RabbitTemplateAware` 并实现 `RabbitListener` 接口:
```java
import org.springframework.amqp.core.Message;
import org.springframework.amqp.rabbit.annotation.RabbitListener;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;
@Component
public class ConfirmMessageConsumer {
@Autowired
private RabbitTemplate rabbitTemplate;
@RabbitListener(queues = "confirm-queue", consumerProperties = "x-dead-letter-exchange=dead-letter-exchange")
public void handleConsumeAck(Message message) {
// 处理收到的消息确认,比如记录日志、更新状态等
String correlationId = message.getHeaders().get("correlationId");
System.out.println("Received acknowledge for correlation ID: " + correlationId);
try {
// 发送消息确认,如采用AMQP的Confirm模式,则调用confirmSelect()
rabbitTemplate.confirmSelect();
} catch (IOException e) {
// 处理确认失败的情况
e.printStackTrace();
}
}
}
```
4. **开启异步回调**:确保在发送消息时使用 `sendAndDeclare` 或 `convertAndSend` 方法,它们会自动触发回调处理:
```java
@Autowired
private RabbitTemplate rabbitTemplate;
// 发送消息
rabbitTemplate.convertAndSend("exchange-name", "routing-key", yourPayload, headers -> {
headers.put("correlationId", generateCorrelationId()); // 设置关联ID
});
```
