最近做servlet发现了个问题，解决办法记下来：

Servlet eroor：HTTP method GET is not supported by this URL

错误提示：

type: Status report

message: HTTP method GET is not supported by this URL

description: The specified HTTP method is not allowed for the requested resource (HTTP method GET is not supported by this URL).

返回状态代码为405的HTTP错误表示对于指定资源的请求方法不被允许。

Servlet 出错：

Servlet eroor ：HTTP method GET is not supported by this UR

type: Status report

message: HTTP method GET is not supported by this URL

description: The specified HTTP method is not allowed for the requested resource ( HTTP method GET is not supported by this ).

也有可能是这样的：

Servlet eroor ：HTTP method GET is not supported by this UR

type: Status report

message: HTTP method POST is not supported by this URL

description: The specified HTTP method is not allowed for the requested resource ( HTTP method GET is not supported by this ).

原因是GET或POST不被支持。

解决方法：

如果你出错的是HTTP method GET is not supported by this ，则用doGet调用doPost. 如：

 1 protected void doGet(HttpServletRequest req, HttpServletResponse resp)
 2    throws ServletException, IOException {
 3   doPost(req,resp);
 4  }
 5 
 6 
 7  protected void doPost(HttpServletRequest req, HttpServletResponse resp)
 8    throws ServletException, IOException {
 9   ……
10 
11   ……
12  }

如果错误是HTTP method POST is not supported by this ，则用doPost调用doGet,如：

 1 protected void doPost(HttpServletRequest req, HttpServletResponse resp)
 2    throws ServletException, IOException {
 3   doPost(req,resp);
 4  }
 5 
 6 
 7  protected void doGet(HttpServletRequest req, HttpServletResponse resp)
 8    throws ServletException, IOException {
 9   ……
10 
11   ……
12  }
