contextpath, servletpath, requesturi, realpath

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
