【问题标题】：Retrieving Datasource JDBC connection string via JMX from IBM Websphere通过 JMX 从 IBM Websphere 检索数据源 JDBC 连接字符串
【发布时间】：2015-10-02 09:49:08
【问题描述】：

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。有人知道如何检索这些信息吗？

属性：

dbcDriver: WebSphere:name=...
connectionFactoryType: interface javax.sql.DataSource
dataSourceName: 
dataStoreHelperClass: description: New JDBC Datasource
loginTimeout: statementCacheSize: 10
jtaEnabled: true

stateManageable: false
statisticsProvider: false
eventProvider: false

stuckThreshold: 0
surgeThreshhold: -1

【解决方案1】：

简而言之，不，您无法从任何当前提供的 JMX bean 中获取连接 URL。

WebSphere Liberty 公开 JDBC 连接 URL 的唯一方式是通过 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();

【讨论】：

注意ds.getConnection()打开一个连接。
