Spring Boot 集成配置 ​

一、概述 ​

Spring Boot 提供了对 RabbitMQ 的自动配置支持，通过简单的配置即可快速集成 RabbitMQ。本文档详细介绍 Spring Boot 与 RabbitMQ 的集成配置方式。

1.1 集成架构 ​

四、实际应用场景 ​

4.1 微服务配置 ​

yaml
spring:
  application:
    name: order-service
  rabbitmq:
    host: ${RABBITMQ_HOST:rabbitmq}
    port: ${RABBITMQ_PORT:5672}
    username: ${RABBITMQ_USERNAME:order_service}
    password: ${RABBITMQ_PASSWORD}
    virtual-host: /production
    
    publisher-confirm-type: correlated
    publisher-returns: true
    
    listener:
      simple:
        acknowledge-mode: manual
        concurrency: 5
        max-concurrency: 15
        prefetch: 20
        
app:
  rabbitmq:
    exchanges:
      order:
        name: order.exchange
        type: topic
        durable: true
      payment:
        name: payment.exchange
        type: direct
        durable: true
    queues:
      order-created:
        name: order.created.queue
        durable: true
        arguments:
          x-message-ttl: 86400000
          x-dead-letter-exchange: dlx.exchange
      payment-completed:
        name: payment.completed.queue
        durable: true
    bindings:
      order-binding:
        queue: order.created.queue
        exchange: order.exchange
        routing-key: order.#

4.2 健康检查配置 ​

java
import org.springframework.amqp.rabbit.connection.ConnectionFactory;
import org.springframework.amqp.rabbit.core.RabbitTemplate;
import org.springframework.boot.actuate.health.Health;
import org.springframework.boot.actuate.health.HealthIndicator;
import org.springframework.stereotype.Component;

@Component
public class RabbitMQHealthIndicator implements HealthIndicator {
    
    private final RabbitTemplate rabbitTemplate;
    
    public RabbitMQHealthIndicator(RabbitTemplate rabbitTemplate) {
        this.rabbitTemplate = rabbitTemplate;
    }
    
    @Override
    public Health health() {
        try {
            rabbitTemplate.execute(channel -> {
                channel.getConnectionFactory().createConnection().close();
                return null;
            });
            
            return Health.up()
                .withDetail("status", "connected")
                .build();
        } catch (Exception e) {
            return Health.down()
                .withDetail("error", e.getMessage())
                .build();
        }
    }
}

五、常见问题与解决方案 ​

5.1 连接失败 ​

问题描述： 应用启动时无法连接到 RabbitMQ。

解决方案：

yaml
spring:
  rabbitmq:
    connection-timeout: 60000
    listener:
      simple:
        auto-startup: false

5.2 消息丢失 ​

问题描述： 消息发送后丢失。

解决方案：

yaml
spring:
  rabbitmq:
    publisher-confirm-type: correlated
    publisher-returns: true
    template:
      mandatory: true

5.3 消费者阻塞 ​

问题描述： 消费者处理缓慢导致消息堆积。

解决方案：

yaml
spring:
  rabbitmq:
    listener:
      simple:
        prefetch: 10
        concurrency: 5
        max-concurrency: 20
