我最近在尝试通过java Web应用程序访问我的数据库时遇到了问题。我不断收到 CannotGetJdbcConnectionException 以及 StaleConnectionException 。我使用Websphere v8.5作为本地计算机服务器。我已经尝试在管理控制台中测试数据源连接，它总是成功返回。但每当我尝试访问我的应用程序时，我都会得到上述异常。有没有人知道为什么会这种情况发生以及我怎么可能解决它？以下是我不断收到的错误消息。
我正在使用DB2作为我的数据库

我对该主题进行了更多的研究，尤其是StaleConnectionException，并且大部分文章都讨论了JDBC异常超时或过时的问题。所以我进入了Websphere管理控制台，开始寻找有关连接的属性。在资源 - ＆gt; JDBC - ＆gt;数据源 - ＆gt; [您的数据源] 有一个关于“ Websphere Application Server数据源属性”的页面，其中有一个名为“连接验证属性”的部分。我决定尝试一下并检查验证新连接复选框，并将重试次数和重试间隔保留为默认设置并进行测试应用程序，它工作。
