Question

我正在运行ActiveMQ 5.5.1并且遇到了配置日志式JDBC持久性的问题。使用the example here，我收到以下XML验证错误：

./activemq console xbean:my-activemq.xml

我已经审核了the published schema，但它似乎与此示例完全不同，因此很明显两个来源中的一个不同步。任何人都可以使用Journaled JDBC与MySQL共享他们的工作持久性配置吗？

以下是我配置的相关部分：

<bean id="mysql-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>

  <persistenceFactory>
    <journaledJDBC journalLogFiles="5" dataDirectory="${activemq.base}/activemq-data" dataSource="#mysql-ds"/>
  </persistenceFactory>

您可以尝试使用以下配置设置持久性适配器：

<persistenceFactory>
    <journalPersistenceAdapterFactory journalLogFiles="5" dataDirectory="${activemq.base}/data" dataSource="#mysql-ds">
    </journalPersistenceAdapterFactory>
</persistenceFactory>

它对我有用，但是如果您计划使用故障转移，请注意期刊的缺点 - 它们根本不能一起工作（在奴隶经纪人身上没有您的期刊副本）。经过考虑后，我们决定使用没有日记功能的sql server持久性，它对发布者和订阅者的故障转移都很好。

使用Journaled MySQL JDBC Persistence设置ActiveMQ
