请求方法“POST”不支持

Question

我有一个弹簧启动应用程序，以及 我试图用POST方法下面的控制器发送对象：

@PostMapping("/suggestevent") 
    public String receiveSuggestedEvent(@ModelAttribute SuggestedEvent event) { 

     return "redirect:/suggestEvent"; 
    } 

，但它与抱怨：

There was an unexpected error (type=Method Not Allowed, status=405). 
Request method 'POST' not supported 

那么，什么是错的？

更新： 我已经试过这一点，它也没有工作

@RequestMapping(value = "/suggestevent", method = RequestMethod.POST) 

表单包含一些简单的inputes和选择，其工作原理基于Thyemeleaf。这里是我的形式：

<form th:action="@{/suggestevent}" method="post"> 

       <div class="form-group"> 
        <label for="title">Title</label> 
        <input type="text" 
         class="form-control" id="title" placeholder="Event title" 
         th:value="${event.title}" 
         name="title" required="required"/> 
       </div> 

       <div class="form-group"> 
        <label for="mainFouce">Main Focus</label> 
        <input type="text" 
         class="form-control" id="Focus" placeholder="Focus" 
         th:value="${event.mainFouce}" 
         name="Focus" required="required"/> 
       </div> 

       Event Type 
       <div class="form-group"> 
        <select class="form-control" name="type" th:value="${event.type}"> 
         <option value="volvo">Party</option> 
         <option value="saab">Workshop</option> 
         <option value="fiat">Friendship</option> 
        </select> 
       </div> 

       <div class="form-group"> 
        <label for="city">Area</label> 
        <input type="text" 
         class="form-control" id="area" 
         th:value="${event.area}" 
         placeholder="Berlin, Estonia ,or even Asia" name="area" 
         required="required"/> 
       </div> 

       <div class="form-group"> 
        <label for="description">Description</label> 
        <textarea name="description" class="form-control" 
         th:value="${event.description}" 
         required="required" form="usrform" 
         placeholder="What makes it an special event?"></textarea> 
       </div> 

       <button type="submit" class="btn btn-default">Submit</button> 
      </form> 

的发送对象是：

@Entity 
@Data 
public class SuggestedEvent { 

    @Id 
    @GeneratedValue 
    Long id; 

    String title; 
    String mainFouce; 
    EventType type; 
    String area; 
    String description; 

} 

邮递员可以顺利到达控制器，但thyemeleaf抱怨！

当您尝试添加表格内的空SuggestedEvent对象，并尝试填充这样的对象，因此，会发生什么：

<form th:action="@{/suggestevent}" th:object="${event}" method="post"> 
       <div class="form-group"> 
        <label for="title">Title</label> 
        <input type="text" 
         class="form-control" id="title" placeholder="Event title" 
         th:value="*{title}" 
         name="title" required="required"/> 
       </div> 

       <div class="form-group"> 
        <label for="mainFouce">Main Focus</label> 
        <input type="text" 
         class="form-control" id="Focus" placeholder="Focus" 
         th:value="*{mainFouce}" 
         name="Focus" required="required"/> 
       </div> 

       Event Type 
       <div class="form-group"> 
        <select class="form-control" name="type" th:value="*{type}"> 
         <option value="volvo">Party</option> 
         <option value="saab">Workshop</option> 
         <option value="fiat">Friendship</option> 
        </select> 
       </div> 

       <div class="form-group"> 
        <label for="city">Area</label> 
        <input type="text" 
         class="form-control" id="area" 
         th:value="*{area}" 
         placeholder="Berlin, Estonia ,or even Asia" name="area" 
         required="required"/> 
       </div> 

       <div class="form-group"> 
        <label for="description">Description</label> 
        <textarea name="description" class="form-control" 
         th:value="*{description}" 
         required="required" form="usrform" 
         placeholder="What makes it an special event?"></textarea> 
       </div> 

    <button class="btn btn-default">Submit</button> 
</form> 

而在@GetMapping("/suggestEvent")：

@GetMapping("/suggestEvent") 
    public String getSuggestEventPage(Model model) { 
    model.addAttribute("event", new SuggestEvent()); 

    return "suggestEventPage"; 
    } 

时退房官方Thymeleaf doc否则。这应该不是一个问题，因为我在my project中完全一样。
