HttpServletRequest 中 getRequestURL和getRequestURI的区别

HttpServletRequest中 getRequestURL和getRequestURI的区别

比如说有这样的一个页面

test1.jsp=======================

<a href ="test.jsp?name=wf">跳转到test2.jsp</a>

test2.jsp======================= 

HttpServletRequestreq = (HttpServletRequest)request;

HttpServletResponseresp = (HttpServletResponse) response;

String servletPath= req.getRequestURI()

String servletPath= req.getRequestURL()

得到的值为：req.getRequestURI()-----> /test/test.jsp 

  req.getRequestURL()-----> http://localhost:8080/test/test.jsp
