ActiveMQ消息持久机制中配置JDBC With journal教程

由于JDBC with journal的性能优于jdbc,所以推荐使用JDBC with journal,下面配置JDBC with journal
把默认的kanhaDB注释掉,改为

<persistenceFactory>
    <journalPersistenceAdapterFactory 
        journalLogFiles="4"
        journalLogFileSize="32768"
        useJournal="true"
        useQuickJournal="true"
        dataSource="#mysql-ds"
        dataDirectory="activemq-data"/>         
</persistenceFactory>

如图

继续在actvemq.xml中添加数据源, 添加在之后和标签之前

   <bean id="mysql-ds" class="org.apache.commons.dbcp2.BasicDataSource" destroy-method="close">
        <property name="driverClassName" value="com.mysql.jdbc.Driver"/>
         <property name="url" value="jdbc:mysql://192.168.78.130:3306/activemq?relaxAutoCommit=true"/>
        <property name="username" value="root"/>
        <property name="password" value="root"/>
        <property name="poolPreparedStatements" value="true"/>
   </bean>

ActiveMQ.xml文件配置图
到这里已经配置完成,也可以直接拷贝下面完整配置文件
