request.getRequestURI() 、 request.getRequestURL() 、 request.getContextPath() 、 request.getServletPath() 区别 request.getRequestURI() /jqueryWeb/resources/request.jsp request.getRequestURL() http://localhost:8080/jqueryWeb/resources/requ

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

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


注: resourcesWebContext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

  2System.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
