【RabbitMQ】08 深入部分P1 可靠性投递
1、消息投递确认
这里的代码延用了06的东西：
https://www.cnblogs.com/mindzone/p/15374684.html
删除之前的整合案例，重新写了一份案例的队列和交换机配置
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context" xmlns:rabbit="http://www.springframework.org/schema/rabbit" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context https://www.springframework.org/schema/context/spring-context.xsd http://www.springframework.org/schema/rabbit http://www.springframework.org/schema/rabbit/spring-rabbit.xsd"> <!--加载配置文件--> <context:property-placeholder location="classpath:rabbitmq.properties"/> <!-- 定义rabbitmq connectionFactory publisher-confirms="true" 消息发送可确认 publisher-returns="true" --> <rabbit:connection-factory id="connectionFactory" host="${rabbitmq.host}" port="${rabbitmq.port}" username="${rabbitmq.username}" password="${rabbitmq.password}" virtual-host="${rabbitmq.virtual-host}" publisher-confirms="true" publisher-returns="true" /> <!--定义管理交换机、队列--> <rabbit:admin connection-factory="connectionFactory"/> <!--定义rabbitTemplate对象操作可以在代码中方便发送消息--> <rabbit:template id="rabbitTemplate" connection-factory="connectionFactory"/> <!-- 消息可靠性投递 --> <rabbit:queue id="confirm-test-queue" name="confirm-test-queue" /> <rabbit:direct-exchange name="confirm-test-exchange" > <rabbit:bindings> <rabbit:binding queue="confirm-test-queue" key="confirm" /> </rabbit:bindings> </rabbit:direct-exchange> </beans>
测试类：
package cn.dzz; import org.junit.Test; import org.junit.runner.RunWith; import org.springframework.amqp.rabbit.connection.CorrelationData; import org.springframework.amqp.rabbit.core.RabbitTemplate; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.test.context.ContextConfiguration; import org.springframework.test.context.junit4.SpringJUnit4ClassRunner; @RunWith(SpringJUnit4ClassRunner.class) @ContextConfiguration(locations = "classpath*:producer-config.xml") public class SpringProducerTest { @Autowired private RabbitTemplate rabbitTemplate; /** * 消息送出可靠性测试 * 1、xml配置数据连接工厂开启消息可确认设置 √ * 2、rabbitTemplate对象定义回调函数 */ @Test public void sendingReliableTest() { /** * CorrelationData correlationData相关配置信息 * boolean ack 来自交换机收到消息的确认参数 true收到了 false没收到 * String cause 失败的原因信息 发送成功了就没有失败原因 case为null */ rabbitTemplate.setConfirmCallback((correlationData, ack, cause) -> { System.out.println("确认消息真的从生产者服务发送到了RabbitMQ中间件这里， 然后这个周期的时刻需要做的什么事情 。。。。"); if (ack) { System.out.println("rabbitMQ收到消息了 " + cause); } else { System.out.println("rabbitMQ没收到消息 ： cause by " + cause); // 如果没收到就需要做对应的处理逻辑 } }); rabbitTemplate.convertAndSend("confirm-test-exchange", "confirm", " 发送一条消息以测试confirm回调。。。。"); } }
可靠投递确认就是设置两样东西
1、连接工厂开启确认项配置
2、模板对象重写确认回调函数
正常编写配置，执行结果肯定是消息发送正常

如果更改错误的配置：
把交换机故意写错，
rabbitTemplate.convertAndSend("confirm-test-exchange222", "confirm", " 发送一条消息以测试confirm回调。。。。");
然后则输出：

3、消费确认
Ack 确认的意思，即消费者服务收到了来自RabbitMQ队列发送的消息之后，需要做出回应
这个过程就是确认
确认的三种方式
1、自动确认，RabbitMQ发送给消费者服务之后默认认为确认已收到
2、手动确认，等待消费者做出回应之后确认
3、根据异常来进行确认

RabbitMQ默认状态是使用none表示确认状态
手动签收确认的配置：

监听器实现调整：

报错之后 执行拒绝签收，RabbitMQ会一直重新发送消息
消息状态处于一直未签收的状态：
异常处理的两个方法区别：就是Nack可以处理多条消息，Reject只能一条
