使用Osgi中的Jersey在REST服务中使用应用程序/json

我正在使用Jersey在Osgi包中部署一些REST服务。服务的符号如下所示

@POST
@Path("/adduser")
@Consumes(MediaType.APPLICATION_XML+","+MediaType.APPLICATION_JSON)
@Produces(MediaType.APPLICATION_XML)
public Message addUser(User user) {
 ...
}

我遇到的第一个问题是，服务不接受我放入@Consumes符号中的两种MIME类型，而只接受第一种

第二个也是最糟糕的是，当我尝试调用服务时，会收到以下异常。例如，我可以@Consumes text/plain，也可以@products application/xml，但是如果我试图@Consumes一个应用程序/json或应用程序/xml，服务器就会抛出异常

当我使用REST客户机或ajax调用使用格式良好的json或xml进行调用时，会抛出异常，如果服务只接收文本/纯文本或未接收任何内容，则对客户机的响应是正确的xml，因此当我发送POJO但未接收它们时，序列化器工作正常
