有关请求路径的总结 request.getContextPath()、request.getServletContext().getRealPath("")、request.getRequestURI

请求路径的URL http://localhost:8080/electest/system/elecMenuAction_menuHome.do
System.out.println("contentType------"+request.getContentType());

System.out.println("requestcontextPath------"+request.getContextPath());

System.out.println("servletPath----"+request.getServletPath());

System.out.println("requestRealPath"+request.getRealPath(""));

System.out.println("realPath------"+request.getServletContext().getRealPath(""));

System.out.println("requestURI------"+request.getRequestURI());

System.out.println("requestURL-------"+request.getRequestURL());

System.out.println("contextPath-------"+request.getServletContext().getContextPath());
