本文整理了Java中javax.sql.ConnectionEvent.getSQLException()方法的一些代码示例，展示了ConnectionEvent.getSQLException()的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。ConnectionEvent.getSQLException()方法的具体详情如下：
包路径：javax.sql.ConnectionEvent
类名称：ConnectionEvent
方法名：getSQLException

ConnectionEvent.getSQLException介绍

[英]Gets the SQLException which holds information about the error which occurred in the PooledConnection.
[中]获取SQLException，该异常保存有关PooledConnection中发生的错误的信息。
