request.getRequestURI 与request.getServletPath() 区别

路径：resin/webapps/my_proj/test/request.jsp

http://localhost:8080/my_proj/test/request.jsp?***

?

request.getRequestURI() /my_proj/test/request.jsp
request.getRequestURL() http://localhost:8080/my_proj/test/request.jsp
request.getContextPath() /my_proj 带/WEB-INF的目录地址
request.getServletPath()? /test/request.jsp

?

貌似request.getRequestURI() 为request.getContextPath()+request.getServletPath()
