Spring MVC HTTP状态405-不支持请求方法“ POST”-骨干请求
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!
回答:
您已经映射/api/messages
到getMessagesInJSON
仅允许GET请求的方法。您的POST请求正在映射到其他路径。
建议您在的请求映射上省略value属性createMessage
。
@RequestMapping(method = RequestMethod.POST )
