springboot整合rabbitmq合集(xml方式和注解方式)

首先介绍一下rabbitmq三种模式

1. Direct–路由模式
   任何发送到Direct Exchange的消息都会被转发到RouteKey指定的Queue。
   这种模式下不需要将Exchange进行任何绑定(binding)操作。
   消息传递时需要一个“RouteKey”，可以简单的理解为要发送到的队列名字。
   如果vhost中不存在RouteKey中指定的队列名，则该消息会被抛弃。
   
   
   
   

2. Fanout–发布/订阅模式
   任何发送到Fanout Exchange的消息都会被转发到与该Exchange绑定(Binding)的所有Queue上。
   这种模式不需要RouteKey。
   这种模式需要提前将Exchange与Queue进行绑定，一个Exchange可以绑定多个Queue，一个Queue可以同多个Exchange进行绑定。
   如果接受到消息的Exchange没有与任何Queue绑定，则消息会被抛弃。
   
   
   
   

3. Topic–匹配订阅模式
   任何发送到Topic Exchange的消息都会被转发到所有关心RouteKey中指定话题的Queue上。
   就是每个队列都有其关心的主题，所有的消息都带有一个“标题”(RouteKey)，Exchange会将消息转发到所有关注主题能与RouteKey模糊匹配的队列。
   这种模式需要RouteKey，也许要提前绑定Exchange与Queue。
   在进行绑定时，要提供一个该队列关心的主题。
   .“#”表示0个或若干个关键字，“*”表示一个关键字。
   同样，如果Exchange没有发现能够与RouteKey匹配的Queue，则会抛弃此消息。
   
   
   
   
   
   

springboot整合rabbitmq基于注解方式(最简单方式)

pom文件配置

<?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"

接下来就是配置文件

spring.application.name=springboot-rabbitmq
server.port=8080
//默认地址就是127.0.0.1：5672，如果是服务器的rabbitmq就改下
spring.rabbitmq.host=127.0.0.1
spring.rabbitmq.port=5672
spring.rabbitmq.username=guest
spring.rabbitmq.password=guest
//消息确认模式，还有一种事务模式，这里不讲解，有兴趣自己去查资料
spring.rabbitmq.publisher-confirms=true
//这里我把他看作是虚拟主机目录，相当于数据库的库名
spring.rabbitmq.virtual-host=/

第一步配置生产者

package com.example.annotion.demo.sender;

import java.util.Date;

import org.springframework.amqp.core.AmqpTemplate;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;

@Component
public class Sender {

    //rabbitTemplate.convertAndSend(String exchange交换机名称(可省略), String routingKey路由键, Object object传递的消息）
    @Autowired
    private AmqpTemplate rabbitTemplate;

    //direct方式交换机名字随便填，但是不能填direct，会造成两次消费
    public void sendDirect() {
        String msg1 = "hello " + new Date();
        System.out.println("helloSender : " + msg1);
        this.rabbitTemplate.convertAndSend("hello", msg1);
//        this.rabbitTemplate.convertAndSend("direct","hello", msg1);
        String msg2 = "user " + new Date();
        System.out.println("userSender : " + msg2);
        this.rabbitTemplate.convertAndSend("user", msg2);
//        this.rabbitTemplate.convertAndSend("direct","user", msg2);
    }

	//topic方式
    public void sendTopic() {
        String msg1 = "I am topic.mesaage msg======";
        System.out.println("topic.mesaage sender : " + msg1);
        this.rabbitTemplate.convertAndSend("exchange", "topic.message", msg1);

        String msg2 = "I am topic.mesaages msg########";
        System.out.println("topic.mesaages sender : " + msg2);
        this.rabbitTemplate.convertAndSend("exchange", "topic.messages", msg2);
    }

    //fanout方式routingKey随便填
    public void sendFanout() {
        String msg = "I am fanoutSender msg======";
        System.out.println("fanoutSender : " + msg);
        this.rabbitTemplate.convertAndSend("fanoutExchange", "suibiantian",msg);
    }


}

接下来就是消费者

package com.example.annotion.demo.receiver;

import org.springframework.amqp.core.ExchangeTypes;
import org.springframework.amqp.rabbit.annotation.*;
import org.springframework.stereotype.Component;

/**
 *     @RabbitListener()rabbit监听
 *     @QueueBinding()队列绑定 value绑定@Queue，exchange绑定@Exchange，key为路由键
 *     @Queue队列 value：名称；autoDelete：是否自动删除，当最后一个消费者断开连接之后队列是否自动被删除；durable： 是否持久化, 队列的声明默认是存放到内存中的，如果rabbitmq重启会丢失，如果想重启之后还存在就要使队列持久化，保存到Erlang自带的Mnesia数据库中，当rabbitmq重启之后会读取该数据库
 *     @Exchange交换器，type有五种，其余参数同@Queue
 */
@Component
public class Receiver {

    //===============以下是验证direct Exchange的队列==========
//    @RabbitListener(queues = "hello")
    //direct模式，exchange名字随便填
    @RabbitListener(bindings = @QueueBinding(
            value = @Queue(value = "hello",autoDelete = "false",declare = "true"),exchange = @Exchange(value = "suibianxie",type = ExchangeTypes.DIRECT),key = "user"
    ))
    @RabbitHandler
    public void processHello(String msg) {
        System.out.println("helloReceiver  : " + msg);
    }

//    @RabbitListener(queues = "user")
    @RabbitListener(bindings = @QueueBinding(
            value = @Queue(value = "user",autoDelete = "false"),exchange = @Exchange(value = "suibianxie",type = ExchangeTypes.DIRECT),key = "hello"
    ))
    @RabbitHandler
    public void processUser(String msg) {
        System.out.println("userReceiver  : " + msg);
    }

    //===============以上是验证direct Exchange的队列==========




    //===============以下是验证topic Exchange的队列==========
//    @RabbitListener(queues = "topic.message")
    @RabbitListener(bindings = @QueueBinding(
            value = @Queue(value = "topic.message",autoDelete = "false"),exchange = @Exchange(value = "exchange",type = ExchangeTypes.TOPIC),key = "topic.message"
    ))
    @RabbitHandler
    public void processTopicMessage(String msg) {
        System.out.println("topicMessageReceiver  : " + msg);
    }

//    @RabbitListener(queues = "topic.messages")
    @RabbitListener(bindings = @QueueBinding(
            value = @Queue(value = "topic.messages",autoDelete = "false"),exchange = @Exchange(value = "exchange",type = ExchangeTypes.TOPIC),key = "topic.#"
    ))
    @RabbitHandler
    public void processTopicMessages(String msg) {
        System.out.println("topicMessagesReceiver  : " + msg);
    }

    //===============以上是验证topic Exchange的队列==========






    //===============以下是验证fanout Exchange的队列==========
//    @RabbitListener(queues = "fanout.A")
    //fanout方式key不用填
    @RabbitListener(bindings = @QueueBinding(
            value = @Queue(value = "fanout.A",autoDelete = "false"),exchange = @Exchange(value = "fanoutExchange",type = ExchangeTypes.FANOUT)
    ))
    @RabbitHandler
    public void processFanoutA(String msg) {
        System.out.println("fanoutAReceiver  : " + msg);
    }

//    @RabbitListener(queues = "fanout.B")
    @RabbitListener(bindings = @QueueBinding(
            value = @Queue(value = "fanout.B",autoDelete = "false"),exchange = @Exchange(value = "fanoutExchange",type = ExchangeTypes.FANOUT)
    ))
    @RabbitHandler
    public void processFanoutB(String msg) {
        System.out.println("fanoutBReceiver  : " + msg);
    }

//    @RabbitListener(queues = "fanout.C")
    @RabbitHandler
    @RabbitListener(bindings = @QueueBinding(
            value = @Queue(value = "fanout.C",autoDelete = "false"),exchange = @Exchange(value = "fanoutExchange",type = ExchangeTypes.FANOUT)
    ))
    public void processFanoutC(String msg) {
        System.out.println("fanoutCReceiver  : " + msg);
    }

    //===============以上是验证fanout Exchange的队列==========

}

再来一个controller方便测试

package com.example.annotion.demo.controller;

import com.example.annotion.demo.sender.Sender;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

@RestController
@RequestMapping("/rabbit")
public class RabbitController {
    
    @Autowired
    private Sender sender;

    
    @GetMapping("/direct")
    public void direct() {
        sender.sendDirect();
    }

    @GetMapping("/topic")
    public void topic() {
        sender.sendTopic();
    }

    @GetMapping("/fanout")
    public void fanout() {
        sender.sendFanout();
    }

}

启动项目，分别访问127.0.0.1:8080/rabbit/direct,127.0.0.1:8080/rabbit/topic,127.0.0.1:8080/rabbit/fanout三个地址看看效果。

springboot整合rabbitmq基于注解方式

这种注解方式其实原理和上面一样，只是消费者的RabbitListener只要配置一个queue的名称，其他配置同意提取到一个配置类中
消费者代码

package com.example.annotion.demo.receiver;

import org.springframework.amqp.core.ExchangeTypes;
import org.springframework.amqp.rabbit.annotation.*;
import org.springframework.stereotype.Component;


@Component
public class Receiver {

    //===============以下是验证direct Exchange的队列==========
    @RabbitListener(queues = "hello")
    @RabbitHandler
    public void processHello(String msg) {
        System.out.println("helloReceiver  : " + msg);
    }

    @RabbitListener(queues = "user")
    @RabbitHandler
    public void processUser(String msg) {
        System.out.println("userReceiver  : " + msg);
    }

    //===============以上是验证direct Exchange的队列==========




    //===============以下是验证topic Exchange的队列==========
    @RabbitListener(queues = "topic.message")
    @RabbitHandler
    public void processTopicMessage(String msg) {
        System.out.println("topicMessageReceiver  : " + msg);
    }

    @RabbitListener(queues = "topic.messages")
    @RabbitHandler
    public void processTopicMessages(String msg) {
        System.out.println("topicMessagesReceiver  : " + msg);
    }

    //===============以上是验证topic Exchange的队列==========






    //===============以下是验证fanout Exchange的队列==========
    @RabbitListener(queues = "fanout.A")
    @RabbitHandler
    public void processFanoutA(String msg) {
        System.out.println("fanoutAReceiver  : " + msg);
    }

    @RabbitListener(queues = "fanout.B")
    @RabbitHandler
    public void processFanoutB(String msg) {
        System.out.println("fanoutBReceiver  : " + msg);
    }

    @RabbitListener(queues = "fanout.C")
    @RabbitHandler
    public void processFanoutC(String msg) {
        System.out.println("fanoutCReceiver  : " + msg);
    }

    //===============以上是验证fanout Exchange的队列==========

}

配置类代码

package com.example.annotion.demo.config;

import org.springframework.amqp.core.*;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Primary;
import org.springframework.stereotype.Component;

@Component
public class QueueCofig {

    //===============以下是验证direct Exchange的队列==========
    @Bean
    public Queue helloQueue() {
        return new Queue("hello");
    }
    
    @Bean
    public Queue userQueue() {
        return new Queue("user");
    }

    /**
     *注入name为'direct'的DirectExchange,默认名字就是空字符串，可以不注入
     */
    @Bean
    DirectExchange directExchange() {
        return new DirectExchange("direct");
    }

    /**
     * 将队列hello与exchange绑定，binding_key为hello,就是完全匹配
     */
    @Bean
    Binding bindingHelloExchange(Queue helloQueue, DirectExchange exchange) {
        return BindingBuilder.bind(helloQueue).to(exchange).with("hello");
    }

    /**
     * 将队列user与exchange绑定，binding_key为hello,就是完全匹配
     */
    @Bean
    Binding bindingUserExchange(Queue userQueue, DirectExchange exchange) {
        return BindingBuilder.bind(userQueue).to(exchange).with("user");
    }

    //===============以上是验证direct Exchange的队列==========

    //===============以下是验证topic Exchange的队列==========
    @Bean
    public Queue queueMessage() {
        return new Queue("topic.message");
    }

    @Bean
    public Queue queueMessages() {
        return new Queue("topic.messages");
    }


    /**
     *注入name为exchange的TopicExchange
     */
    @Bean
    TopicExchange exchange() {
        return new TopicExchange("exchange");
    }

    /**
     * 将队列topic.message与exchange绑定，binding_key为topic.message,就是完全匹配
     */
    @Bean
    Binding bindingExchangeMessage(Queue queueMessage, TopicExchange exchange) {
        return BindingBuilder.bind(queueMessage).to(exchange).with("topic.message");
    }

    /**
     * 将队列topic.messages与exchange绑定，binding_key为topic.#,模糊匹配
     */
    @Bean
    Binding bindingExchangeMessages(Queue queueMessages, TopicExchange exchange) {
        return BindingBuilder.bind(queueMessages).to(exchange).with("topic.#");
    }


    //===============以上是验证topic Exchange的队列==========
    
    
    //===============以下是验证Fanout Exchange的队列==========
    @Bean
    public Queue AMessage() {
        return new Queue("fanout.A");
    }

    @Bean
    public Queue BMessage() {
        return new Queue("fanout.B");
    }

    @Bean
    public Queue CMessage() {
        return new Queue("fanout.C");
    }


    /**
     * 注入name为fanoutExchange的FanoutExchange
     */
    @Bean
    FanoutExchange fanoutExchange() {
        return new FanoutExchange("fanoutExchange");
    }



    /**
     * 将队列fanout.A与FanoutExchange绑定
     */
    @Bean
    Binding bindingExchangeA(Queue AMessage,FanoutExchange fanoutExchange) {
        return BindingBuilder.bind(AMessage).to(fanoutExchange);
    }

    /**
     * 将队列fanout.B与FanoutExchange绑定
     */
    @Bean
    Binding bindingExchangeB(Queue BMessage, FanoutExchange fanoutExchange) {
        return BindingBuilder.bind(BMessage).to(fanoutExchange);
    }

    /**
     * 将队列fanout.C与FanoutExchange绑定
     */
    @Bean
    Binding bindingExchangeC(Queue CMessage, FanoutExchange fanoutExchange) {
        return BindingBuilder.bind(CMessage).to(fanoutExchange);
    }
    //===============以上是验证Fanout Exchange的队列==========



}

结果如下

springboot整合rabbitmq基于xml方式

这种方式比较麻烦，但是呢，有些老项目可能是这么用的，所以在这里也做一个demo。
pom文件和上面一样，配置文件把mq的配置去掉，第一步设置配置类，加载xml文件

package com.example.xml.demo.config;

import org.springframework.amqp.rabbit.annotation.EnableRabbit;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.ImportResource;

/**
 * 实例化xml文件中定义的bean
 **/
@Configuration
@EnableRabbit
@ImportResource({ "classpath:config/applicationContext-*.xml" })
public class XmlConfig {

}

第二步就是配置文件，这里我分了两个配置文件，把不改变的连接信息之类的放在单独的配置文件，这部分文件配置即可发送mq消息

<?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"
       xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
                            http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd">

    <!-- 读取配置文件, 多个properties文件可以用英文逗号分隔 -->
    <context:property-placeholder ignore-resource-not-found="true" location="classpath*:/rabbitmq.properties" file-encoding="UTF-8"/>
    <!-- 公共部分 -->
    <!-- 创建连接类 连接安装好的 rabbitmq -->
    <bean id="connectionFactory"  class="org.springframework.amqp.rabbit.connection.CachingConnectionFactory">
        <constructor-arg value="localhost" />
        <!-- username,访问RabbitMQ服务器的账户,默认是guest -->
        <property name="username" value="${rmq.manager.user}" />
        <!-- username,访问RabbitMQ服务器的密码,默认是guest -->
        <property name="password" value="${rmq.manager.password}" />
        <!-- host,RabbitMQ服务器地址，默认值"localhost" -->
        <property name="host" value="${rmq.ip}" />
        <!-- port，RabbitMQ服务端口，默认值为5672 -->
        <property name="port" value="${rmq.port}" />
    </bean>
    <bean id="amqpAdmin" class="org.springframework.amqp.rabbit.core.RabbitAdmin">
        <constructor-arg ref="connectionFactory" />
    </bean>

    <bean id="rabbitTemplate" class="org.springframework.amqp.rabbit.core.RabbitTemplate">
        <constructor-arg ref="connectionFactory"></constructor-arg>
    </bean>


    <!-- 声明消息转换器为SimpleMessageConverter -->
    <bean id="messageConverter"
          class="org.springframework.amqp.support.converter.SerializerMessageConverter">
    </bean>
</beans>

引入了rabbitmq.properties

rmq.ip=127.0.0.1
rmq.port=5672
rmq.manager.user=guest
rmq.manager.password=guest

接下来就是消费者的一些监听绑定的xml

接下来我们的接受类com.example.xml.demo.receiver.Receiver

package com.example.xml.demo.receiver;

import org.springframework.amqp.rabbit.annotation.RabbitHandler;
import org.springframework.amqp.rabbit.annotation.RabbitListener;
import org.springframework.stereotype.Component;

public class Receiver {


    public void processHello(String msg) {
        System.out.println("helloReceiver  : " + msg);
    }


    public void processUser(String msg) {
        System.out.println("userReceiver  : " + msg);
    }


    public void processTopicMessage(String msg) {
        System.out.println("topicMessageReceiver  : " + msg);
    }


    public void processTopicMessages(String msg) {
        System.out.println("topicMessagesReceiver  : " + msg);
    }


    public void processFanoutA(String msg) {
        System.out.println("fanoutAReceiver  : " + msg);
    }


    public void processFanoutB(String msg) {
        System.out.println("fanoutBReceiver  : " + msg);
    }


    public void processFanoutC(String msg) {
        System.out.println("fanoutCReceiver  : " + msg);
    }


}

生产者类代码

package com.example.xml.demo.sender;

import org.springframework.amqp.core.AmqpTemplate;
