我是Spring MVC的新手，我正在尝试使用Spring MVC + Hibernate从头开始构建Web应用程序，以提供类似JSON Rest
API的功能，并通过客户端在Backbone上使用此API。为此，我已经开始遵循本教程（http://www.mkyong.com/spring-
mvc/spring-3-mvc-and-json-example/
）。

So I have a model Message which will have the following REST API Interface:
GET /api/messages               ( working ok )
GET /api/messages/:id           ( working ok )
DELETE /api/messages/:id        ( working ok )
PUT /api/messages/:id           ( working ok )
POST /api/messages              ( error: (DefaultHandlerExceptionResolver.java:194) - Request method 'POST' not supported)

我希望通过表单执行请求时，对于PUT或DELETE请求会发生此问题，而对于POST请求，则不会发生。我什至没有通过表格提出要求。在客户端，请求是通过Backbone完成的，如下所示：

new App.Models.Message({ attributeA : 'a', attributeB : 'b' }).save();

我已经尝试按照其他Stackoverflow问题中的建议在web.xml上添加httpMethodFilter：

 <filter>
    <filter-name>httpMethodFilter</filter-name>
    <filter-class>org.springframework.web.filter.HiddenHttpMethodFilter</filter-class>
 </filter>

 <filter-mapping>
    <filter-name>httpMethodFilter</filter-name>
    <servlet-name>mvc-dispatcher</servlet-name>
 </filter-mapping>

有人遇到过同样的问题吗？

我在这里离开我的MessagesController：

@Controller
@RequestMapping("/api/messages")
public class MessagesController {

    @Autowired  
    private MessageService messageService;

    @RequestMapping(method = RequestMethod.GET)
    public @ResponseBody List<Message> getMessagesInJSON(@RequestParam( value = "type", required = false ) String type) {   
        List<Message> messages = messageService.findAll();          
        return messages; 
    }

    @RequestMapping( value = "/{id}", method = RequestMethod.GET )
    public @ResponseBody Message getMessageInJson(@PathVariable Integer id ) {      
        Message message = messageService.findById(id);
        return message;     
    }

    @RequestMapping( value = "/{id}", method = RequestMethod.DELETE )
    @ResponseStatus( value = HttpStatus.NO_CONTENT )
    public void deleteMessage(@PathVariable Integer id ) throws NotFoundException {     
        messageService.delete(id);      
    }

    @RequestMapping( value = "/{id}", method = RequestMethod.PUT )
    @ResponseStatus( value = HttpStatus.NO_CONTENT )
    public void editMessage( @PathVariable Integer id, @RequestBody Message message ) throws NotFoundException {
        message.setId(id);
        messageService.update(message);
    }

    @RequestMapping( value = "/", method = RequestMethod.POST )
    @ResponseStatus(HttpStatus.CREATED)
    public @ResponseBody Message createMessage( @RequestBody Message message ) {        
        return messageService.create(message);
    }

}

非常感谢！
