假定你的web application 名称为qlumeeting，你在浏览器中输入请求路径：

http://localhost/qlumeeting/login.html

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

打印结果：/qlumeeting

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

打印结果：/login.html

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

打印结果：/qlumeeting/login.html

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

打印结果：F:\Tomcat 6.0\webapps\news\test
