通过 JMX 从 IBM Websphere 检索数据源 JDBC 连接字符串
Retrieving Datasource JDBC connection string via JMX from IBM Websphere
我想知道是否可以从 IBM Websphere Application Server 检索数据源的 JDBC 连接字符串。我已经可以访问数据源的 JMX Bean，但似乎没有属性或操作（见下文）公开 JDBC 连接 URL 字符串。有人知道如何检索此信息吗？

=====================================
简而言之，不，您无法从任何当前提供的 JMX bean 获得连接URL。
WebSphere Liberty 公开 JDBC 连接 URL 的唯一方法是通过 java.sql.DatabaseMetaData.getURL() API。如果您可以获得对 DataSource 对象的引用（通过 JNDI 查找或 @Resource 注入），您可以从中获取连接，获取 DatabaseMetaData 然后调用 getURL().
DataSource ds = (DataSource) new InitialContext().lookup("jdbc/name");
String url = ds.getConnection().getMetaData().getURL();
