mysql - 无法实例化持久性管理器org.apache.jackrabbit.core.persistence.pool.MySqlPersistenceManager

Question

我已使用 jackrabbit-jca-2.6.4.rar 在 Glassfish 4 中部署了 Jackrabbit 2.6.4。

当我使用以下配置时一切正常(通过 JDBC 进行 Derby):

    <PersistenceManager class="org.apache.jackrabbit.core.persistence.pool.DerbyPersistenceManager">
      <param name="url" value="jdbc:derby:${wsp.home}/db;create=true"/>
      <param name="schemaObjectPrefix" value="${wsp.name}_"/>
    </PersistenceManager>

但是当我切换到这个(Mysql 通过数据源)时:

    <PersistenceManager class="org.apache.jackrabbit.core.persistence.pool.MySqlPersistenceManager">
      <param name="url" value="jdbc/MySQLDataSource"/>
      <param name="driver" value="javax.naming.InitialContext"/>
      <param name="schemaObjectPrefix" value="${wsp.name}_"/>
    </PersistenceManager>

我已经在Glassfish中配置了Mysql JDBC连接池和JDBC连接资源(jdbc/MySQLDataSource)，并将mysql-connector-java-5.1.26-bin.jar放在domain/lib目录中。我可以通过管理 UI 中的 Glassfish JDBC 连接池页面成功 ping 数据库。

我是否在 JackRabbit PersistanceManager 配置中遗漏了某些内容？

更新1

如果我不使用数据源，而是在 PersistanceManager 配置中使用 JDBC URL 来连接到数据库，它将按预期工作。

Answer 1

原来是Mysql JDBC连接池配置不正确。

为了让它工作，我必须设置以下属性:

• 用户
• 密码
• 数据库名称
• 服务器名称
• 网址
• 网址

我还必须在 Url 和 URL 字段中重复数据库和服务器名称，例如

jdbc:mysql://127.0.0.1:3306/db_name

此时我不确定为什么有一个 Url 和一个 URL 属性，但将它们都设置为上面的 URL 是有效的。
