推荐答案

不要使用Struts来配置数据源。 Struts是一个表示框架。它与数据库无关。

Don't use Struts to configure a data source. Struts is a presentation framework. It has nothing to do with databases.

请参阅 http://tomcat.apache.org/tomcat-7.0-doc/jndi-datasource-examples-howto.html 如何在Tomcat上部署的应用程序中声明和使用DataSource。

See http://tomcat.apache.org/tomcat-7.0-doc/jndi-datasource-examples-howto.html for how to declare and use a DataSource in an application deployed on Tomcat.
