执行结果：

当前WEB应用的物理路径：F:\115Synchronization\code save\JSP\

当前你求请的JSP文件的物理路径：F:\115Synchronization\code save\JSP\web\web\src\fundation\getPath.jsp

当前JSP文件所在目录的物理路径F:\115Synchronization\code save\JSP\web\web\src\fundation

web URL 路径:http://localhost:8080/web/web/src/fundation/

getContextPath: /web

getServletPath: /web/src/fundation/
