假定你的web application 名称为news,你在浏览器中输入请求路径:
http://localhost:8080/news/main/list.jsp
则执行下面向行代码后打印出如下结果:
1、 System.out.println(request.getContextPath());
打印结果:/news
2、System.out.println(request.getServletPath());
打印结果:/main/list.jsp
3、 System.out.println(request.getRequestURI());
打印结果:/news/main/list.jsp
4、 System.out.println(request.getRealPath("/"));
打印结果: F:\Tomcat 6.0\webapps\news\test
