Question

如何将日期值发送到Webservice Request中的Calendar对象。

@Produces("application/json")
@Path("Service")
public class ServiceImpl {

    @Context
    HttpServletRequest httpServletRequest;
    @Context
    HttpServletResponse httpServletResponse;

    @POST
    @Path("getDetails")
    @Consumes("application/json")
    @Produces("application/json")
    public String getDetails (ServiceRequest request)
    {
    if(null!=request)
    return "Successfully Parsed given Date";
    }
}

public class ServiceRequest {

    private XMLGregorianCalendar requestDate;

    void setDate(XMLGregorianCalendar date){
    this.requestDate = date;
    }
    XMLGregorianCalendar getDate()
    {
    return requestDate;
    }
}

请求网址： http://localhost:7001/WebProject/Service/getDetails

RequestParams：

{
"requestDate" : "2015-04-20T05:30:00.000Z"
}

它没有将值解析为日期。我怎么能为Calendar对象传递值。

使用genson jar来序列化请求。错误信息就像

如果您使用的是Genson 1.2且年龄大于是，那么评论中指出的两个答案应该适合您。从Genson 1.3开始，围绕配置JAX-RS扩展进行了轻微的重构，所以现在它应该更容易实现。使用Jersey的一个例子：

Genson genson = new GensonBuilder()
  .useDateFormat(yourDateFormat)
  .create();

new ResourceConfig().register(new GensonJaxRSFeature().use(genson));

但注册自定义实例的旧方法仍应继续使用1.3及更高版本。

以下是有关jax-rs和configuration的相关文档。
