Spring Boot 配置多源的 RabbitMQ

简介

mq 是开发中很平常的中间件，本文讲述的是怎么在一个spring boot项目中配置多源的rabbitmq，这里不过多的讲解rabbitmq的相关知识点。如果你也有遇到需要往多个rabbitmq中发送消息的需求，希望本文可以帮助到你。

环境

• rabbitmq 3.7.12
• spring boot 2.1.6.release

当然软件的版本不是硬性要求，只是我使用的环境而已，唯一的要求是需要启动两个rabbitmq，我这边是在kubernetes集群中使用helm官方提供的charts包快速启动的两个rabbitmq-ha高可用rabbitmq集群。

想要了解 kubernetes或者helm,可以参看以下 github仓库：

• helm:
• charts:

springboot中配置两个rabbitmq源

在springboot 中配置单个rabbitmq是极其简单的，我们只需要使用springboot为我们自动装配的rabbitmq相关的配置就可以了。但是需要配置多个源时，第二个及其以上的就需要单独配置了，这里我使用的都是单独配置的。

代码：

/**
 * @author innerpeacez
 * @since 2019/3/11
 */
@data
public abstract class abstractrabbitconfiguration {

    protected string host;
    protected int port;
    protected string username;
    protected string password;

    protected connectionfactory connectionfactory() {
        cachingconnectionfactory connectionfactory = new cachingconnectionfactory();
        connectionfactory.sethost(host);
        connectionfactory.setport(port);
        connectionfactory.setusername(username);
        connectionfactory.setpassword(password);
        return connectionfactory;
    }
}

第一个源的配置代码

package com.zhw.study.springbootmultirabbitmq.config;

import org.springframework.amqp.rabbit.config.simplerabbitlistenercontainerfactory;
import org.springframework.amqp.rabbit.connection.connectionfactory;
import org.springframework.amqp.rabbit.core.rabbitadmin;
import org.springframework.amqp.rabbit.core.rabbittemplate;
import org.springframework.beans.factory.annotation.qualifier;
import org.springframework.boot.autoconfigure.amqp.simplerabbitlistenercontainerfactoryconfigurer;
import org.springframework.boot.context.properties.configurationproperties;
import org.springframework.context.annotation.bean;
import org.springframework.context.annotation.configuration;
import org.springframework.context.annotation.primary;

/**
 * @author innerpeacez
 * @since 2019/3/8
 */

@configuration
@configurationproperties("spring.rabbitmq.first")
public class firstrabbitconfiguration extends abstractrabbitconfiguration {

    @bean(name = "firstconnectionfactory")
    @primary
    public connectionfactory firstconnectionfactory() {
        return super.connectionfactory();
    }

    @bean(name = "firstrabbittemplate")
    @primary
    public rabbittemplate firstrabbittemplate(@qualifier("firstconnectionfactory") connectionfactory connectionfactory) {
        return new rabbittemplate(connectionfactory);
    }

    @bean(name = "firstfactory")
    public simplerabbitlistenercontainerfactory firstfactory(simplerabbitlistenercontainerfactoryconfigurer configurer,
                                                             @qualifier("firstconnectionfactory") connectionfactory connectionfactory) {
        simplerabbitlistenercontainerfactory factory = new simplerabbitlistenercontainerfactory();
        configurer.configure(factory, connectionfactory);
        return factory;
    }

    @bean(value = "firstrabbitadmin")
    public rabbitadmin firstrabbitadmin(@qualifier("firstconnectionfactory") connectionfactory connectionfactory) {
        return new rabbitadmin(connectionfactory);
    }
}

第二个源的配置代码

package com.zhw.study.springbootmultirabbitmq.config;

import org.springframework.amqp.rabbit.config.simplerabbitlistenercontainerfactory;
import org.springframework.amqp.rabbit.connection.connectionfactory;
import org.springframework.amqp.rabbit.core.rabbitadmin;
import org.springframework.amqp.rabbit.core.rabbittemplate;
import org.springframework.beans.factory.annotation.qualifier;
import org.springframework.boot.autoconfigure.amqp.simplerabbitlistenercontainerfactoryconfigurer;
import org.springframework.boot.context.properties.configurationproperties;
import org.springframework.context.annotation.bean;
import org.springframework.context.annotation.configuration;

/**
 * @author innerpeacez
 * @since 2019/3/8
 */

@configuration
@configurationproperties("spring.rabbitmq.second")
public class secondrabbitconfiguration extends abstractrabbitconfiguration {

    @bean(name = "secondconnectionfactory")
    public connectionfactory secondconnectionfactory() {
        return super.connectionfactory();
    }

    @bean(name = "secondrabbittemplate")
    public rabbittemplate secondrabbittemplate(@qualifier("secondconnectionfactory") connectionfactory connectionfactory) {
        return new rabbittemplate(connectionfactory);
    }

    @bean(name = "secondfactory")
    public simplerabbitlistenercontainerfactory secondfactory(simplerabbitlistenercontainerfactoryconfigurer configurer,
                                                             @qualifier("secondconnectionfactory") connectionfactory connectionfactory) {
        simplerabbitlistenercontainerfactory factory = new simplerabbitlistenercontainerfactory();
        configurer.configure(factory, connectionfactory);
        return factory;
    }

    @bean(value = "secondrabbitadmin")
    public rabbitadmin secondrabbitadmin(@qualifier("secondconnectionfactory") connectionfactory connectionfactory) {
        return new rabbitadmin(connectionfactory);
    }
}

配置信息

spring:
  application:
    name: multi-rabbitmq
  rabbitmq:
    first:
      host: 192.168.10.76
      port: 30509
      username: admin
      password: 123456
    second:
      host: 192.168.10.76
      port: 31938
      username: admin
      password: 123456

测试

这样我们的两个rabbitmq源就配置好了，接下来我们进行测试使用，为了方便使用，我写了一个multirabbittemplate.class 方便我们使用不同的源。

/**
 * @author innerpeacez
 * @since 2019/3/8
 */
@component
public abstract class multirabbittemplate {

    @autowired
    @qualifier(value = "firstrabbittemplate")
    public amqptemplate firstrabbittemplate;

    @autowired
    @qualifier(value = "secondrabbittemplate")
    public amqptemplate secondrabbittemplate;
}

第一个消息发送者类 testfirstsender.class

/**
 * @author innerpeacez
 * @since 2019/3/11
 */
@component
@slf4j
public class testfirstsender extends multirabbittemplate implements messagesender {

    @override
    public void send(object msg) {
        log.info("rabbitmq1 , msg: {}", msg);
        firstrabbittemplate.convertandsend("rabbitmq1", msg);
    }

    public void rabbitmq1sender() {
        this.send("innerpeacez1");
    }
}

第二个消息发送者类 testsecondsender.class

/**
 * @author innerpeacez
 * @since 2019/3/11
 */
@component
@slf4j
public class testsecondsender extends multirabbittemplate implements messagesender {

    @override
    public void send(object msg) {
        log.info("rabbitmq2 , msg: {}", msg);
        secondrabbittemplate.convertandsend("rabbitmq2", msg);
    }

    public void rabbitmq2sender() {
        this.send("innerpeacez2");
    }
}

动态创建queue的消费者

/**
 * @author innerpeacez
 * @since 2019/3/11
 */

@slf4j
@component
public class testfirstconsumer implements messageconsumer {

    @override
    @rabbitlistener(bindings = @queuebinding(value = @queue("rabbitmq1")
            , exchange = @exchange("rabbitmq1")
            , key = "rabbitmq1")
            , containerfactory = "firstfactory")
    public void receive(object obj) {
        log.info("rabbitmq1 , {}", obj);
    }

}

/**
 * @author innerpeacez
 * @since 2019/3/11
 */

@slf4j
@component
public class testsecondconsumer implements messageconsumer {

    @override
    @rabbitlistener(bindings = @queuebinding(value = @queue("rabbitmq2")
            , exchange = @exchange("rabbitmq2")
            , key = "rabbitmq2")
            , containerfactory = "secondfactory")
    public void receive(object obj) {
        log.info("rabbitmq2 , {}", obj);
    }

}

测试类

@runwith(springrunner.class)
@springboottest
@slf4j
public class springbootmultirabbitmqapplicationtests extends multirabbittemplate {

    @autowired
    private testfirstsender firstsender;
    @autowired
    private testsecondsender secondsender;

    /**
     * 一百个线程向 first rabbitmq 的 rabbitmq1 queue中发送一百条消息
     */
    @test
    public void testfirstsender() {
        for (int i = 0; i < 100; i++) {
            new thread(() ->
                    firstsender.rabbitmq1sender()
            ).start();
        }
        try {
            thread.sleep(1000 * 10);
        } catch (interruptedexception e) {
            e.printstacktrace();
        }
    }

    /**
     * 一百个线程向 second rabbitmq 的 rabbitmq2 queue中发送一百条消息
     */
    @test
    public void testsecondsender() {
        for (int i = 0; i < 100; i++) {
            new thread(() ->
                    secondsender.rabbitmq2sender()
            ).start();
        }
        try {
            thread.sleep(1000 * 10);
        } catch (interruptedexception e) {
            e.printstacktrace();
        }

    }
}

测试结果：

总结

这样配置好之后我们就可向两个rabbitmq中发送消息啦。这里只配置了两个源，当然如果你需要更多的源，仅仅只需要配置*rabbitconfiguration.class就可以啦。本文没有多说关于rabbitmq的相关知识，如果未使用过需要自己了解一下相关知识。
