从Jersey返回JSONP似乎不起作用

Question

我使用的是Jersey 2.22.1，看起来很简单。我已经有了返回json的端点，现在我希望它们返回jsonp。似乎所有我要做的就是使用@JSONP进行注释，但是当我测试时，我没有看到回调包装。

来自文档：

@GET
@JSONP
@Produces({"application/json", "application/javascript"})
public JaxbBean getSimpleJSONP() {
    return new JaxbBean("jsonp");
}

我的代码：

@GET
@Path("/jsonp")
@JSONP
@Produces({"application/json", "application/javascript"})
public Response getHeathJsonp() {
    return Response.ok().entity(ApplicationStatus.getNew("HEALTHY", "Application is healthy!")).build();
}

我的jquery电话：

   $.ajax({
      url: "http://foo.com/api/health/jsonp",
      dataType: 'jsonp',
      type: 'GET',
      data: "",
      success: function(data) {
        console.log(data);
      },
      error: function(xhr, status, err) {
        console.log(err.toString());
      }
    });

我的ApplicationStatus bean： 包com.foo.model.application;

import org.joda.time.DateTime;

public class ApplicationStatus {

    private String _status;
    private String _description;
    private DateTime _dateTime;

    private ApplicationStatus() {   }

    public static ApplicationStatus getNew(String status, String desc) {
        ApplicationStatus stat = new ApplicationStatus();
        stat.setDateTime(DateTime.now());
        stat.setStatus(status);
        stat.setDescription(desc);
        return stat;
    }

    public String getStatus() {
        return _status;
    }

    public void setStatus(String _status) {
        this._status = _status;
    }

    public String getDescription() {
        return _description;
    }

    public void setDescription(String _description) {
        this._description = _description;
    }

    public DateTime getDateTime() {
        return _dateTime;
    }

    public void setDateTime(DateTime _dateTime) {
        this._dateTime = _dateTime;
    }

}

这个bean上的json序列化在我的常规json端点上运行得很好，但是jsonp似乎不起作用......它很简单，我甚至无法确定可能出错的地方。
