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

1.1 System.out.println(request.getContextPath());

打印结果:/news

1.2 System.out.println(request.getServletPath());

打印结果:/main/list.jsp

1.3 System.out.println(request.getRequestURI());

打印结果:/news/main/list.jsp

1.4 System.out.println(request.getRealPath("/"));

打印结果:F:\Tomcat 6.0\webapps\news\test

${pageContext.request.contextPath}是JSP取得绝对路径的方法,等价于<%=request.getContextPath()%> 。
