HTTP method POST is not supported by this URL解決

標籤：exception   send   沒有   stat   pattern   void   class   uil   stream   

今天寫了個非常簡單的setvlet想測試些東西，寫好了後用postman請求報錯，報錯內容如下

{    "timestamp": 1504170113588,    "status": 405,    "error": "Method Not Allowed",    "message": "HTTP method POST is not supported by this URL",    "path": "/vincent/aaa"}

但是我的控制台還是答應了我的請求內容，百思不得其解，最後發現是因為沒有把調用父類的post方法刪掉

My Code如下

@WebServlet(urlPatterns = "/aaa")public class MyServlet extends HttpServlet{    @Override    protected void doGet(HttpServletRequest request, HttpServletResponse resp) throws ServletException, IOException {        super.doGet(request, resp);    }    @Override    protected void doPost(HttpServletRequest request, HttpServletResponse resp) throws ServletException, IOException {        InputStream inputStream = request.getInputStream();        BufferedReader in=new BufferedReader(new InputStreamReader(request.getInputStream()));        StringBuilder sb = new StringBuilder();        String xmlHead = "";        String xmlContent="";        String line = null;        while ((line = in.readLine()) != null) {            sb.append(line);        }        System.out.println(sb);        super.doPost(request, resp);    }}

 super.doPost(request, resp);的源碼如下

protected void doPost(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {        String protocol = req.getProtocol();        String msg = lStrings.getString("http.method_post_not_supported");        if (protocol.endsWith("1.1")) {            resp.sendError(405, msg);        } else {            resp.sendError(400, msg);        }    }

有沒有發現，無論你的請求怎樣，他都報錯的。
