无法将数据从 cline 发送到服务器

Question

我尝试从我的 js 调用我的 java 后端

angular js (http://localhost:8082/dev/index.html#/):

self.submit = function() {
  console.log("in voice prompt component - submit");
  console.log(self.voice);
  $http.put('localhost:8082/api/Voices/updateVoice', self.voice).then(
    function successCallback(response) {
      self.voices = response.data;
    },
    function errorCallback(response) {
      // called asynchronously if an error occurs
      // or server returns response with an error status.
      console.log(response); 
    });
}

java（应回应localhost:8082/api/Voices/updateVoice

@Path("/Voices")
public class VoicesOperation {

...

    @Path("/updateVoice")
    @PUT
    @Produces(MediaType.APPLICATION_JSON + ";charset=utf-8")
    public void updateVoice(VoiceBl voice) throws Exception {

        fillVoicesSnapshot();

我得到这个 js 异常：

问题出在你的资源文件上，你没有发送任何东西，也没有使用任何东西。如果您要发送回复，那么您的 return 类型应该是 Response，并且您还需要消费。

@Path("/Voices")
public class VoicesOperation {

...

    @Path("/updateVoice")
    @PUT
    @Consumes(MediaType.APPLICATION_JSON)
    @Produces(MediaType.APPLICATION_JSON + ";charset=utf-8")
    public Response updateVoice(VoiceBl voice) throws Exception {
        Voice voice = fillVoicesSnapshot();
        return Response.status(Status.CREATED)
                       .entity(voice)
                       .build();
    }
}

或者，如果您要发送语音类型，那么您的 return 类型应该是语音。

@Path("/Voices")
public class VoicesOperation {

...

    @Path("/updateVoice")
    @PUT
    @Consumes(MediaType.APPLICATION_JSON)
    @Produces(MediaType.APPLICATION_JSON + ";charset=utf-8")
    public Voice updateVoice(VoiceBl voice) throws Exception {

        return fillVoicesSnapshot();
    } 
}
