RabbitMQ相信大家已经再熟悉不过了,作为业界四大主流消息中间件之一(Apache RocketMQ、Apache Kafka、Apache ActiveMQ、RabbitMQ),它具有非常好的性能和可靠性的集群模式,不仅仅在各大互联网大厂中广泛使用(比如同程艺龙、美团点评等),而且在互联网金融行业也常常被作为首选!SpringBoot作为互联网开发利器已经不需要我再过多介绍什么,接下来我们一起从零开始构建RabbitMQ、并且与SpringBoot2.x的整合吧!
1.安装RabbitMQ集群十步走!(3.6.5版本、采用rpm安装方式,我们要安装3个节点的集群,192.168.11.71 192.168.11.72 192.168.11.73、以71节点为例:)
第一步:下载所需依赖包
Rabbitmq基于erlang语言编写,所以必须要有。
第二步:安装并配置
安装命令:
rpm -ivh erlang-18.3-1.el7.centos.x86_64.rpm
rpm -ivh socat-1.7.3.2-5.el7.lux.x86_64.rpm
rpm -ivh rabbitmq-server-3.6.5-1.noarch.rpm
wget www.rabbitmq.com/releases/erlang/erlang-18.3-1.el7.centos.x86_64.rpm
socat包为秘钥包,如果没有会提示缺少此依赖。
wget http://repo.iotti.biz/CentOS/7/x86_64/socat-1.7.3.2-5.el7.lux.x86_64.rpm
rabbitmq-server-3.6.5核心服务包。
wget www.rabbitmq.com/releases/rabbitmq-server/v3.6.5/rabbitmq-server-3.6.5-1.noarch.rpm
安装成功后:修改配置
vim /usr/lib/rabbitmq/lib/rabbitmq_server-3.6.5/ebin/rabbit.app文件
修改:loopback_users 中的 <<"guest">>,只保留guest
第三步:3个节点同时进行前两步骤操作:(71、72、73)
第四步:启停单点服务与开启管控台
/etc/init.d/rabbitmq-server start | stop | status | restart
分别启动三个节点,然后执行命令启动控制台插件如下:
rabbitmq-plugins enable rabbitmq_management最后使用 guest/guest登录成功即可!
第五步:接下来进行集群构建:
71、72、73任意一个节点为Master(这里选择71为Master)
也就是说我们需要把71的Cookie文件同步到72、73节点上去,先停止所有服务器:/etc/init.d/rabbitmq-server stop
然后进入制定目录(/var/lib/rabbitmq/)并远程copy 文件到72、73节点,如下操作:scp /var/lib/rabbitmq/.erlang.cookie到192.168.11.72和192.168.11.73中
第六步:组成集群
首先启动三个节点:rabbitmq-server -detached
然后把72和73分别加入到71中,组成集群 [--ram]为节点以什么方式加入到集群中
ram为内存 存储 默认不加为disk磁盘存储,操作如下:
node72:rabbitmqctl stop_app
node72:rabbitmqctl join_cluster [--ram] rabbit@bhz71
node72:rabbitmqctl start_app
第七步:修改集群名称:
rabbitmqctl set_cluster_name rabbitmq_cluster1
第八步:查看集群状态:
rabbitmqctl cluster_status ,如下所示表示集群构建OK!
第九步:构建镜像队列,任意节点执行命令如下:
rabbitmqctl set_policy ha-all "^" '{"ha-mode":"all"}'
第十步:查看管控台发现集群已经构建成功!
2.RabbitMQ与SpringBoot2.x整合
生产者端:
第一步:pom.xml配置如下
<?xml version="1.0" encoding="UTF-8"?> <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>com.bfxy</groupId> <artifactId>rabbitmq-springboot-producer</artifactId> <version>0.0.1-SNAPSHOT</version> <packaging>jar</packaging> <name>rabbitmq-springboot-producer</name> <description>rabbitmq-springboot-producer</description> <parent> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-parent</artifactId> <version>2.0.2.RELEASE</version> <relativePath/> <!-- lookup parent from repository --> </parent> <properties> <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding> <java.version>1.8</java.version> </properties> <dependencies> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-test</artifactId> <scope>test</scope> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-amqp</artifactId> </dependency> </dependencies> <build> <plugins> <plugin> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-maven-plugin</artifactId> </plugin> </plugins> </build> </project>
第二步:application.properties配置文件
spring.rabbitmq.addresses=192.168.11.71:5672 spring.rabbitmq.username=guest spring.rabbitmq.password=guest spring.rabbitmq.virtual-host=/ spring.rabbitmq.connection-timeout=15000 spring.rabbitmq.publisher-confirms=true #confirm模式 spring.rabbitmq.publisher-returns=true #return机制 spring.rabbitmq.template.mandatory=true #与return机制结合配置次属性
第三步:编写RabbitSender生产端代码
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; @Component public class RabbitSender { //自动注入RabbitTemplate模板类 @Autowired private RabbitTemplate rabbitTemplate; //回调函数: confirm确认 final ConfirmCallback confirmCallback = new RabbitTemplate.ConfirmCallback() { @Override public 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() { @Override public void returnedMessage(org.springframework.amqp.core.Message message, int replyCode, String replyText, String exchange, String routingKey) { System.err.println("return exchange: " + 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); } }
消费者:
第一步:pom文件同生产者一致
第二步:application.properties配置文件
spring.rabbitmq.addresses=192.168.11.76:5672 spring.rabbitmq.username=guest spring.rabbitmq.password=guest spring.rabbitmq.virtual-host=/ spring.rabbitmq.connection-timeout=15000 spring.rabbitmq.listener.simple.acknowledge-mode=manual #手工签收 spring.rabbitmq.listener.simple.concurrency=5 spring.rabbitmq.listener.simple.max-concurrency=10
第三步:RabbitRecever消费端代码
package com.bfxy.springboot.conusmer; 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.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.*" ) ) @RabbitHandler public 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ACK channel.basicAck(deliveryTag, false); } }
生产端测试:
package com.bfxy.springboot; import java.text.SimpleDateFormat; import java.util.Date; import java.util.HashMap; import java.util.Map; import org.junit.Test; import org.junit.runner.RunWith; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.boot.test.context.SpringBootTest; import org.springframework.test.context.junit4.SpringRunner; import com.bfxy.springboot.producer.RabbitSender; @RunWith(SpringRunner.class) @SpringBootTest public class ApplicationTests { @Test public void contextLoads() { } @Autowired private RabbitSender rabbitSender; private static SimpleDateFormat simpleDateFormat = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss.SSS"); @Test public void testSender1() throws Exception { Map<String, Object> properties = new HashMap<>(); properties.put("number", "12345"); properties.put("send_time", simpleDateFormat.format(new Date())); rabbitSender.send("Hello RabbitMQ For Spring Boot!", properties); } }

这代码很给力,简洁而不乏代表性,易懂且可直接部署运行,必须点个赞

代码和老师的一模一样。消费端channel.basicNack(deliveryTag,false,false)和basicAck的结果为什么怎么都回调不到,channel.addConfirmListener里面的handleack和handlenack都不会被回调到,channel.confirmSelect()也加了,问题来了 怎么去获取消费端ACK的结果或者回调之类的呢,真的求解!!困惑了好久,小伙伴门可以搭个单机版试试,我在家里电脑和公司电脑都试过了!
