RabbitMQ安装和与Sping集成使用

安装

1、安装rabbitmq，此命令会自动安装erlang依赖

sudo apt-get install rabbitmq-server

2、要想在浏览器登录管理页面，需要先安装插件

sudo rabbitmq-plugins enable rabbitmq_management

3、添加用户

sudo rabbitmqctl add_user username password

4、设置用户角色和权限

sudo rabbitmqctl set_user_tags username administrator
sudo rabbitmqctl set_permissions -p / username ".*" ".*" ".*"

执行完以上命令，打开浏览器 http://ip:15672 就可以登录管理页面了

处于安全的考虑，guest这个默认的用户只能通过http://localhost:15672 来登录，其他的IP无法直接使用这个账号。

建立配置文件，新建rabbitmq配置文件  /etc/rabbitmq/rabbitmq.config ， 内容如下：

[{rabbit, [{loopback_users, []}]}].

加入配置之后，重启服务就可以使用guest用户登录了。

更多相关管理命令：

sudo service rabbitmq-server start  /  rabbitmq-server -detached             //启动服务
sudo rabbitmqctl stop                               //关闭服务
sudo rabbitmqctl list_connections              //查看链接
sudo rabbitmqctl list_queues                    //查看队列
sudo rabbitmqctl list_channels                  //查看频道
sudo rabbitmqctl list_users                       //查看全部用户
sudo rabbitmqctl cluster_status                //查看集群状态

 Rabbitmq与Spring集成

 1、添加pom依赖

<dependency>
     <groupId>com.rabbitmq</groupId>
     <artifactId>amqp-client</artifactId>
     <version>4.1.0</version>
 </dependency>

 <dependency>
     <groupId>org.springframework.amqp</groupId>
     <artifactId>spring-rabbit</artifactId>
     <version>1.7.5.RELEASE</version>
 </dependency>

注意：amqp-client   5.x.x.x版本需要jdk1.8支持，所以如果使用的jdk是1.7就必须使用5.x.x.x一下的版本

2、添加配置

    <rabbit:direct-exchange name="first_exchange" durable="true" auto-delete="false" id="second_exchange">
        <rabbit:bindings>
            <rabbit:binding queue="first_queue" key="first_queue"/>
            <rabbit:binding queue="second_queue" key="second_queue"/>
      </rabbit:bindings>
    </rabbit:direct-exchange>
    
    <bean id="firstConsumer" class="com.thinkgem.jeesite.modules.mq.consumer.FirstConsumer"></bean>
    <bean id="secondConsumer" class="com.thinkgem.jeesite.modules.mq.consumer.SecondConsumer"></bean>
    
    <rabbit:listener-container connection-factory="connectionFactory" acknowledge="auto">
        <rabbit:listener queues="first_queue" method="onMessage" ref="firstConsumer"/>
    </rabbit:listener-container>
    <rabbit:listener-container connection-factory="connectionFactory" acknowledge="auto">
        <rabbit:listener queues="second_queue" method="onMessage" ref="secondConsumer"/>
    </rabbit:listener-container>
        
</beans>

rabbitmq.properties如下：

rabbit.hosts=192.168.78.132
rabbit.username=admin
rabbit.password=admin
rabbit.port=5672
rabbit.virtualHost=/

消费者实现如下:

package com.thinkgem.jeesite.modules.mq.consumer;

import org.springframework.amqp.core.Message;
import org.springframework.amqp.core.MessageListener;
import org.springframework.beans.factory.annotation.Autowired;


public class FirstConsumer implements MessageListener {

    @Override
    public void onMessage(Message msg) {
        try{
            String body = new String(msg.getBody(), "UTF-8");
            System.out.println("In::: " + body);
            // 消息处理逻辑
            
            
        }catch(Exception e){
            e.printStackTrace();
        }
    }

}

另外一个就省略不贴了。。。

使用 Stomp协议实现web客户端通信

1、rabbitmq安装stomp插件，官方链接

sudo rabbitmq-plugins enable rabbitmq_stomp

服务端和客户端具体配置请参考：待续。。。。。。
