Servlet路径问题

今天看公司框架的源码时，看到路径的问题，不是很清楚，到底哪个是哪个，就自己测了一下：

	protected void doGet(HttpServletRequest request,
			HttpServletResponse response) throws ServletException, IOException {
		System.out.println("getRequestURL:  " + request.getRequestURL());
		System.out.println("getRequestURI:  " + request.getRequestURI());
		System.out.println("getScheme:  " + request.getScheme());
		System.out.println("getServerName:  " + request.getServerName());
		System.out.println("getServerPort:  " + request.getServerPort());
		System.out.println("getContextPath:  " + request.getContextPath());
		System.out.println("getServletPath:  " + request.getServletPath());
	}

 然后访问，结果如下：

getRequestURL:  http://localhost:8080/TestServlet/Test
getRequestURI:  /TestServlet/Test
getScheme:  http
getServerName:  localhost
getServerPort:  8080
getContextPath:  /TestServlet
getServletPath:  /Test
