request.getRequestURI() 、request.getRequestURL() 、request.getContextPath()、request.getServletPath

request.getRequestURI() /jqueryWeb/resources/request.jsp 

request.getRequestURL() http://localhost:8080/jqueryWeb/resources/request.jsp request.getContextPath()/jqueryWeb 

request.getServletPath()/resources/request.jsp   

注： resources为WebContext下的目录名 jqueryWeb 为工程名   

----------------------------------------------------- <%=request.getRequestURI() %><br/> <%=request.getRequestURL() %><br/> <%=request.getContextPath()%><br/> <%=request.getServletPath() %><br/> <%=request.getPathInfo() %><br/> 结果： 

/test-struts.jsp 
http://127.0.0.1:8080/test-struts.jsp  

/test-struts.jsp null  配置： 

<action name="test" class="testStrutsAction" method="test">     <result>/test-struts.jsp</result> </action>   

 

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
