一：搭建及运行

1：解压下载好的activemq压缩包

2：进入${dir}/apache-activemq-5.5.0/bin目录，双击运行activemq.bat，

等待出现：

3：进入http://127.0.0.1:8161/admin/(这是activemq自带的一个web项目,进入的账号密码在配置文件中指定，稍后会讲)，

图中红色标识的是：当前服务器有那些主题，及该主题的生产消费情况。主题可在自己的web项目中指定,稍后会讲。

二：开始建立自己的web工程

     2.1:建立maven项目,引入jar,具体如下:

1.  
   <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
2.  
   xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">

16.  
    <log4j.version>1.2.17</log4j.version>
17.  
    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
18.

     注意：上面的pom.xml主要是引入了这几个包

  

  2.2:然后修改application-context,xml,主要是在项目中配置activemq

1.  
   <beans xmlns="http://www.springframework.org/schema/beans"

三：解释配置文件

        到这一步基本完成了整合,具体要注意的步骤有一下几点:

        3.1: org.apache.activemq.ActiveMQConnectionFactory:是连接工厂,该类的构造方法传递了连接服务的用户名和密码,服务器的ip，注意该ip可以是个集群.用户名密码的指定配置在${dir}\apache-activemq-5.9.0\conf\activemq.xml中的<broker></broker>标签内添加如下标签:

1.  
   <plugins>
2.  
   <simpleAuthenticationPlugin>
3.  
   <users>
4.  
   <authenticationUser username="lcm" password="lcm" groups="admins"></authenticationUser>
5.  
   </users>
6.  
   </simpleAuthenticationPlugin>
7.  
   </plugins>

       3.2:activemq.xml文件中的用户名密码与自己项目配置文件里关于activemq配置的用户名密码一致,然后连接工厂的第三个参数为activemq的服务器ip,它采用tcp连接,并且failover进行集群,并附带超时参数2000ms，其中的连接端口可以更改，具体在:${dir}\apache-activemq-5.9.0\conf\activemq.xml的

        3.3:构造队列:org.apache.activemq.command.ActiveMQQueue：构造方法中指定了自己队列的名称

         3.4:整合jms:

1.  
   <bean id="jmsTemplate" class="org.springframework.jms.core.JmsTemplate">
2.  
   <property name="connectionFactory" ref="connectionFactory" />
3.  
   <property name="defaultDestination" ref="destination" />
4.  
   </bean>

        3.5:再接着整合自己编写的消息接受类和发送类,这个两个类主要是是实现了一些监听方法,然后做自己的业务处理

1.  
   <bean id="messageSender" class="activemq.publisher.MessageSender">
2.  
   <constructor-arg index="0" ref="jmsTemplate" />
3.  
   <constructor-arg index="1" ref="destination" />
4.  
   </bean>
5.  
   <bean id="messageReceiver" class="activemq.consumer.MessageReceiver">

        3.6:最后将自己的监听类和配置activemq的消息队列及actiemq的连接工厂整合到jms监听中

1.  
   <bean class="org.springframework.jms.listener.SimpleMessageListenerContainer">
2.  
   <property name="connectionFactory" ref="connectionFactory" />
3.  
   <property name="destinationName" value="myQueueName" /><!--消费发送者指定的队列名称-->
4.  
   <property name="messageListener" ref="messageReceiver" />
5.  
   </bean>

 

四：项目中的使用场景及额外注意步骤:

       activemq是在高并发下将请求处理的队列化，它自身处理多线程等一系列问题，所以我们直接用即可,监听好它的消息，然后一步步将队列中的请求消费完。

      提到高并发就不由想到nginx，有了nginx负载不就完了吗？为什么还用消息队列呢？

      答案如下：1:系统的瓶颈往往出在数据库,nginx的架构适合于多系统多数据库,对于数据库集群可适用，但这会导致数据同步等一系列问题增多.activemq针对的是单数据库,比如有些场景只使用了一个数据库(类似一些中心数据库),mq使用场景图如下:

 

 

 

 

 

 

                    2:比如持久层数据库和redis同步时，如果出现大量请求,数据同步方案也可以放在activemq队列中处理，防止并发出现的问题

五：注意事项

    使用activemq时，需防止单机宕机导致数据丢失，所以需要处理额外步骤:

        1:需要做集群

        2:做数据持久化,持久方案有多种，目前推荐activemq自带的KahaDB方式处理
