java-POST方法415错误

我有java EE项目。我在此项目上使用Spring Hibernate作为服务器端和Backbone，RequireJS，Jquery作为客户端。我尝试使用POST方法保存但HTTP 415错误返回。java-POST方法415错误

我的Get方法工作正常。我在邮差上测试了它。

我的网址：本地主机：8080/REST /旅游

415不支持的媒体类型请求实体拥有的服务器或资源不支持的媒体类型。例如，客户端将图像上传为image/svg + xml，但服务器要求图像使用不同的格式。你能发布正在发送的消息吗？ –

添加我的帖子数据@MosheArad – real

您应该在这里添加DTO对象结构。模型类不是必需的。 – gaganbm

我错误的原因是这样的骨干代码：

Backbone.emulateJSON = true;

如果Backbone.emulateJSON=true，Content-Type= application/x-www-form-urlencoded。

现在Backbone.emulateJSON=false;问题解决！

@POST 
    @Produces(MediaType.APPLICATION_JSON+ ";charset=UTF-8") 
    @Consumes(MediaType.APPLICATION_JSON) 
     public TravelDTO save(TravelDTO dto) { 
     dto.setUser(userService.get(dto.getUser().getUserID())); 
      dto.setTravelStart(new Date()); 
      dto.setTravelEnd(new Date()); 

      return travelService.save(dto); 
     }

你返回：return travelService.save(dto);

和你宣布你正在返回一个HTT P JSON,

然后只需向您的控制器添加注释@RestController而不是@Controller。

或者只是添加到您的方法@ResponseBody注释。

我正在使用Rest.So我没有控制器class.I只是（模型，服务，资源，dao和dto）但我添加@ResponseBody到POST方法，但同样的415错误继续 – real

你是什么意思“我没有控制器“？如果您在Spring中不使用控制器，您希望从您的服务器接收最终用户的请求吗？ –

https://gist.github.com/berat703/1b54549eecfc4e09534fe1b24e824591 。我的服务类期望从我的服务器接收来自最终用户的请求。我应该删除“@Service”并添加“@RestController”？ – real

HTTP 415正值当

The origin server is refusing to service the request because the payload is in 
a format not supported by this method on the target resource.

编号：https://httpstatuses.com/415

您需要正确设置请求头。根据你所附的图片，你正在通过Content-Type: application/x-www-form-urlencoded。但您的代码需要application/json。

添加下列内容请行家：
