請求的方法POST不受支持，Spring MVC JDBCTemplate

獲取405錯誤：請求方法'POST'在Spring MVC JDBCTemplate CRUD操作中不受支持。請求的方法POST不受支持，Spring MVC JDBCTemplate

How do I resolve 405 'POST' method not supported in the piece of code using Spring MVC and JDBCTemplate for crud operation?

URL訪問DELETE語句：/JdbcTemplate/user/delete/9 這裏的方法是在控制類：

@RequestMapping(value = "/edit/{id}", method = RequestMethod.GET) 
    public ModelAndView editUser(@PathVariable("id") Integer id, ModelMap model) { 

     ModelAndView mav = new ModelAndView(USER_EDIT_PAGE); 
     User user = userService.getUserById(id); 
//  User user = new User(); 
     model.addAttribute("user", user); 
     model.addAttribute("id", id); 
     return mav; 

    } 

    @RequestMapping(value = "/update", method = RequestMethod.POST) 
    public String updateUser(@ModelAttribute("user") User user) { 
     userService.updateUser(user); 
     return "redirect:/user/list"; 
    } 

    @RequestMapping(value = "/delete/{id}", method = RequestMethod.GET) 
    public ModelAndView deleteUser(@PathVariable ("id") Integer id) { 

     ModelAndView mav = new ModelAndView(USER_LIST_VIEW); 

     userService.deleteUser(id); 

     String message = "Team was successfully deleted."; 
     mav.addObject("message", message); 

     return mav; 
    }

現在不知道的JSP當URL傳遞正被稱爲：名單。 JSP

控制器只能識別GET來/刪除/（編號）：

@RequestMapping(value = "/delete/{id}", method = RequestMethod.GET) 
public ModelAndView deleteUser(@PathVariable ("id") Integer id) {

在你的List.jsp有發送POST到/刪除/ {ID}形式，因此，這似乎是在問題：

<form:form action="${pageContext.request.contextPath}/user/delete/${user.id}" method="POST"> 
    <input type="submit" class="btn btn-danger btn-sm" value="Delete" /> 
</form:form>

將窗體上的方法從POST更改爲GET，並且應該可以解決您的問題。如果您希望允許GET和POST到/ delete/{id}，那麼在deleteUser上從@RequestMapping刪除method = RequestMethod.GET將允許它處理所有HTTP方法，而不僅僅是GET。

當我在deleteUser（）方法中從'/ delete/{id}'中移除'method = RequestMethod.GET'時，沒有任何操作或發送的請求不會刪除表中的記錄。 – Thunder
