  • HTTP method POST is not supported by this URL解决

    今天写了个非常简单的setvlet想测试些东西,写好了后用postman请求报错,报错内容如下

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

    但是我的控制台还是答应了我的请求内容,百思不得其解,最后发现是因为没有把调用父类的post方法删掉

    我的代码如下

    @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);的源码如下
    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);
            }
    
        }

    有没有发现,无论你的请求怎样,他都报错的。
