ActiveMQ持久化消息的三种方式

http://www.cnblogs.com/tommyli/archive/2010/09/13/1825205.html

1：前言

     这一段给公司开发消息总线有机会研究ActiveMQ，今天撰文给大家介绍一下他的持久化消息。本文只介绍三种方式,分别是持久化为文件，MYSql，Oracle。下面逐一介绍。

A：持久化为文件

     这个你装ActiveMQ时默认就是这种，只要你设置消息为持久化就可以了。涉及到的配置和代码有

  
    

   
      
   
     <
   
     persistenceAdapter
   
     >
   
     
 
   
     <
   
     kahaDB directory
   
     =
   
     "
   
     ${activemq.base}/data/kahadb
   
     "
   
     />
   
     
 
   
     </
   
     persistenceAdapter
   
     >
   
     

producer.Send(request, MsgDeliveryMode.Persistent, level, TimeSpan.MinValue);
  
    

B：持久化为MySql

     你首先需要把MySql的驱动放到ActiveMQ的Lib目录下，我用的文件名字是：mysql-connector-java-5.0.4-bin.jar

     接下来你修改配置文件

  
    

   
     
   
      
   
     <
   
     persistenceAdapter
   
     >
   
     
 
   
     <
   
     jdbcPersistenceAdapter dataDirectory
   
     =
   
     "
   
     ${activemq.base}/data
   
     "
   
      dataSource
   
     =
   
     "
   
     #derby-ds
   
     "
   
     />
   
     
 
   
     </
   
     persistenceAdapter
   
     >
  
    

在配置文件中的broker节点外增加

  
    

   
     
   
      
   
     <
   
     bean id
   
     =
   
     "
   
     derby-ds
   
     "
   
      
   
     class
   
     =
   
     "
   
     org.apache.commons.dbcp.BasicDataSource
   
     "
   
      destroy
   
     -
   
     method
   
     =
   
     "
   
     close
   
     "
   
     >
   
     
 
   
     <
   
     property name
   
     =
   
     "
   
     driverClassName
   
     "
   
      value
   
     =
   
     "
   
     com.mysql.jdbc.Driver
   
     "
   
     />
   
     
 
   
     <
   
     property name
   
     =
   
     "
   
     url
   
     "
   
      value
   
     =
   
     "
   
     jdbc:mysql://localhost/activemq?relaxAutoCommit=true
   
     "
   
     />
   
     
 
   
     <
   
     property name
   
     =
   
     "
   
     username
   
     "
   
      value
   
     =
   
     "
   
     activemq
   
     "
   
     />
   
     
 
   
     <
   
     property name
   
     =
   
     "
   
     password
   
     "
   
      value
   
     =
   
     "
   
     activemq
   
     "
   
     />
   
     
 
   
     <
   
     property name
   
     =
   
     "
   
     maxActive
   
     "
   
      value
   
     =
   
     "
   
     200
   
     "
   
     />
   
     
 
   
     <
   
     property name
   
     =
   
     "
   
     poolPreparedStatements
   
     "
   
      value
   
     =
   
     "
   
     true
   
     "
   
     />
   
     
 
   
     </
   
     bean
   
     >
  
    

从配置中可以看出数据库的名称是activemq，你需要手动在MySql中增加这个库。

然后重新启动消息队列，你会发现多了3张表

1：activemq_acks

2：activemq_lock

3：activemq_msgs

C：持久化为Oracle

    和持久化为MySql一样。这里我说两点

1；在ActiveMQ安装文件夹里的Lib文件夹中增加Oracle的JDBC驱动。驱动文件位于Oracle客户端安装文件中的product\11.1.0\client_1\jdbc\lib文件夹下。

2：

  
    

   
     
   
      
   
     <
   
     bean id
   
     =
   
     "
   
     derby-ds
   
     "
   
      
   
     class
   
     =
   
     "
   
     org.apache.commons.dbcp.BasicDataSource
   
     "
   
      destroy
   
     -
   
     method
   
     =
   
     "
   
     close
   
     "
   
     >
   
     
 
   
     <
   
     property name
   
     =
   
     "
   
     driverClassName
   
     "
   
      value
   
     =
   
     "
   
     oracle.jdbc.driver.OracleDriver
   
     "
   
     />
   
     
 
   
     <
   
     property name
   
     =
   
     "
   
     url
   
     "
   
      value
   
     =
   
     "
   
     jdbc:oracle:thin:@10.53.132.47:1521:cmfudv1
   
     "
   
     />
   
     
 
   
     <
   
     property name
   
     =
   
     "
   
     username
   
     "
   
      value
   
     =
   
     "
   
     qdcommu
   
     "
   
     />
   
     
 
   
     <
   
     property name
   
     =
   
     "
   
     password
   
     "
   
      value
   
     =
   
     "
   
     qdcommu
   
     "
   
     />
   
     
 
   
     <
   
     property name
   
     =
   
     "
   
     maxActive
   
     "
   
      value
   
     =
   
     "
   
     200
   
     "
   
     />
   
     
 
   
     <
   
     property name
   
     =
   
     "
   
     poolPreparedStatements
   
     "
   
      value
   
     =
   
     "
   
     true
   
     "
   
     />
   
     
 
   
     </
   
     bean
   
     >
  
    

这里的jdbc:oracle:thin:@10.53.132.47:1521:cmfudv1按照自己实际情况设置一下就可以了，特别注意的是cmfudv1是SID即服务名称而不是TNS中配置的节点名。各位同学只需要替换IP,端口和这个SID就可以了。

后记：

这篇文章就是简单的记录一下操作过程，避免后来的同学走弯路。
