jsp 从web.xml读取连接数据库的参数


            jsp或servlet页面代码：复制代码 代码如下:String driver = application. getIni tParameter ("driver") ; String url = application.getInitParameter("url"); String user = application.getInitParameter("user"); String pass = application.getInitParameter("pass");web.xml需要读取的内容： 复制代码 代码如下:<context-param> <param-name>driver</param-name> <param-value>com.mysql.jdbc.Driver</param-value> </context-param> <context-param> <param-name>url</param-name> <param-value>jdbc:mysql://localhost:3306/j2ee</param-value> </context-param> <context-param> <param-name>user</param-name> <param-value>root</param-value> </context-param> <context-param> <param-name>pass</param-name> <param-value>32l47</param-value> </context-param>
