各位大神能否指导一下：

我的后台代码如下，但是前台调用，提示找不到 POST https://我的网站/hello2 NOT FOUND

public class hello {

//@RequestMapping (value="/ServletJon")

@RequestMapping (value="/hello2")

public void hello2(HttpServletRequest request, HttpServletResponse response)

{

   System.out.println(request.getParameter(“city”));

  

   

   

 

}

public void doGet(HttpServletRequest request, HttpServletResponse response)

  throws ServletException, IOException {

   hello2(request, response);

}

}
