自定義servlet

public class TestServlet extends HttpServlet {

	@Override
	protected void doGet(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
		super.doGet(req, resp);
		
	}
}

HttpServlet裏的doGet方法是這樣定義的

    protected void doGet(HttpServletRequest req, HttpServletResponse resp)
            throws ServletException, IOException
    {
        String protocol = req.getProtocol();
        String msg = lStrings.getString("http.method_get_not_supported");
        if (protocol.endsWith("1.1")) {
            resp.sendError(HttpServletResponse.SC_METHOD_NOT_ALLOWED, msg);
        } else {
            resp.sendError(HttpServletResponse.SC_BAD_REQUEST, msg);
        }
    }

所以重寫doGet/doPost方法時，必須先將super.doGet(...)/super.doPost(...)刪掉

自定義servlet重寫doGet或者doPost方法時，405 method not allowed
