SpringBoot 结合 RabbitMQ 简单项目

https://git.coding.net/dgutllx/RabbitmqStudy.git

上面就是我博客里面的项目，感谢大大，学习到不少

publisher-confirms,实现一个监听器用于监听Broker端给我们返回的确认请求：RabbitTemplate.ConfirmCallback
publisher_returns,保证消息对Broker端是可达的，如果出现路由键不可达的情况，则使用监听器对不可达的消息进行后续的处理，保证消息的路由成功：
RabbitTemplate.ReturnCallback

注意一点：在发送消息的时候对template进行配置 mandatory = true 保证监听有效

生产端还可以配置其他属性，比如发送重试，超时时间，次数，间隔等等

spring.rabbitmq.addresses=localhost
spring.rabbitmq.username=guest
spring.rabbitmq.password=guest
spring.rabbitmq.virtual-host=/
spring.rabbitmq.connection-timeout=15000spring.rabbitmq.publisher-confirms=true
spring.rabbitmq.publisher-returns=true
spring.rabbitmq.template.mandatory=true

package com.bfxy.springboot.producer;import java.util.Map;import org.springframework.amqp.rabbit.core.RabbitTemplate;
import org.springframework.amqp.rabbit.core.RabbitTemplate.ConfirmCallback;
import org.springframework.amqp.rabbit.core.RabbitTemplate.ReturnCallback;
import org.springframework.amqp.rabbit.support.CorrelationData;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.messaging.Message;
import org.springframework.messaging.MessageHeaders;
import org.springframework.messaging.support.MessageBuilder;
import org.springframework.stereotype.Component;import com.bfxy.springboot.entity.Order;@Component
public class RabbitSender {//自动注入RabbitTemplate模板类@Autowiredprivate RabbitTemplate rabbitTemplate;  //回调函数: confirm确认final ConfirmCallback confirmCallback = new RabbitTemplate.ConfirmCallback() {@Overridepublic void confirm(CorrelationData correlationData, boolean ack, String cause) {System.err.println("correlationData: " + correlationData);System.err.println("ack: " + ack);if(!ack){System.err.println("异常处理....");}}};//回调函数: return返回final ReturnCallback returnCallback = new RabbitTemplate.ReturnCallback() {@Overridepublic void returnedMessage(org.springframework.amqp.core.Message message, int replyCode, String replyText,String exchange, String routingKey) {System.err.println("return  : " + exchange + ", routingKey: "+ routingKey + ", replyCode: " + replyCode + ", replyText: " + replyText);}};//发送消息方法调用: 构建Message消息public void send(Object message, Map<String, Object> properties) throws Exception {MessageHeaders mhs = new MessageHeaders(properties);Message msg = MessageBuilder.createMessage(message, mhs);rabbitTemplate.setConfirmCallback(confirmCallback);rabbitTemplate.setReturnCallback(returnCallback);//id + 时间戳 全局唯一 CorrelationData correlationData = new CorrelationData("1234567890");rabbitTemplate.convertAndSend("exchange-1", "springboot.abc", msg, correlationData);}//发送消息方法调用: 构建自定义对象消息public void sendOrder(Order order) throws Exception {rabbitTemplate.setConfirmCallback(confirmCallback);rabbitTemplate.setReturnCallback(returnCallback);//id + 时间戳 全局唯一 CorrelationData correlationData = new CorrelationData("0987654321");rabbitTemplate.convertAndSend("exchange-2", "springboot.def", order, correlationData);}}

SpringBoot 整合配置详解之 – 消费端核心配置

spring.rabbitmq.listener.simple.acknowledge-mode=MANUAL
spring.rabbitmq.listener.simple.concurrency=1
spring.rabbitmq.listener.simple.max-concurrency=5

首先配置手工确认模式，用于ACk的手工处理，这样子我们可以保证消息的可靠性送达，或者在消费端消费失败的时候可以做到重回队列，根据业务记录日志等处理

消费端监听 @RabbitMQListener 注解，这个对于在实际工作中非常的好用

@RabbitMQListener是一个组合的注解，里面可以注解配置
@QueueBingding,@Queue , @Exchange直接通过这个组合注解一次性搞定消费端交换机，队列，绑定，路由，并且配置监听功能等

package com.bfxy.springboot.conusmer;import java.util.Map;import org.springframework.amqp.rabbit.annotation.Exchange;
import org.springframework.amqp.rabbit.annotation.Queue;
import org.springframework.amqp.rabbit.annotation.QueueBinding;
import org.springframework.amqp.rabbit.annotation.RabbitHandler;
import org.springframework.amqp.rabbit.annotation.RabbitListener;
import org.springframework.amqp.support.AmqpHeaders;
import org.springframework.messaging.Message;
import org.springframework.messaging.handler.annotation.Headers;
import org.springframework.messaging.handler.annotation.Payload;
import org.springframework.stereotype.Component;import com.rabbitmq.client.Channel;@Component
public class RabbitReceiver {@RabbitListener(bindings = @QueueBinding(value = @Queue(value = "queue-1", durable="true"),exchange = @Exchange(value = "exchange-1", durable="true", type= "topic", ignoreDeclarationExceptions = "true"),key = "springboot.*"))@RabbitHandlerpublic void onMessage(Message message, Channel channel) throws Exception {System.err.println("--------------------------------------");System.err.println("消费端Payload: " + message.getPayload());Long deliveryTag = (Long)message.getHeaders().get(AmqpHeaders.DELIVERY_TAG);//手工ACKchannel.basicAck(deliveryTag, false);}/*** *     spring.rabbitmq.listener.order.queue.name=queue-2spring.rabbitmq.listener.order.queue.durable=truespring.rabbitmq.listener.order.exchange.name=exchange-1spring.rabbitmq.listener.order.exchange.durable=truespring.rabbitmq.listener.order.exchange.type=topicspring.rabbitmq.listener.order.exchange.ignoreDeclarationExceptions=truespring.rabbitmq.listener.order.key=springboot.** @param order* @param channel* @param headers* @throws Exception*/@RabbitListener(bindings = @QueueBinding(value = @Queue(value = "${spring.rabbitmq.listener.order.queue.name}", durable="${spring.rabbitmq.listener.order.queue.durable}"),exchange = @Exchange(value = "${spring.rabbitmq.listener.order.exchange.name}", durable="${spring.rabbitmq.listener.order.exchange.durable}", type= "${spring.rabbitmq.listener.order.exchange.type}", ignoreDeclarationExceptions = "${spring.rabbitmq.listener.order.exchange.ignoreDeclarationExceptions}"),key = "${spring.rabbitmq.listener.order.key}"))@RabbitHandlerpublic void onOrderMessage(@Payload com.bfxy.springboot.entity.Order order, Channel channel, @Headers Map<String, Object> headers) throws Exception {System.err.println("--------------------------------------");System.err.println("消费端order: " + order.getId());Long deliveryTag = (Long)headers.get(AmqpHeaders.DELIVERY_TAG);System.err.println("deliveryTag = "+deliveryTag);//手工ACKchannel.basicAck(deliveryTag, false);}}

PS:由于类配置写在代码里面非常的不友好，所以强烈建议大家使用配置文件配置

spring.rabbitmq.addresses=localhost
spring.rabbitmq.username=guest
spring.rabbitmq.password=guest
spring.rabbitmq.virtual-host=/
spring.rabbitmq.connection-timeout=15000spring.rabbitmq.listener.simple.acknowledge-mode=manual
spring.rabbitmq.listener.simple.concurrency=5
spring.rabbitmq.listener.simple.max-concurrency=10spring.rabbitmq.listener.order.queue.name=queue-2
spring.rabbitmq.listener.order.queue.durable=true
spring.rabbitmq.listener.order.exchange.name=exchange-2
spring.rabbitmq.listener.order.exchange.durable=true
spring.rabbitmq.listener.order.exchange.type=topic
spring.rabbitmq.listener.order.exchange.ignoreDeclarationExceptions=true
spring.rabbitmq.listener.order.key=springboot.*

发送的数据要实现序列化接口

package com.bfxy.springboot.entity;import java.io.Serializable;public class Order implements Serializable {private String id;private String name;public Order() {}public Order(String id, String name) {super();this.id = id;this.name = name;}public String getId() {return id;}public void setId(String id) {this.id = id;}public String getName() {return name;}public void setName(String name) {this.name = name;}}
