如何将JSON请求发布到Jersey REST服务？

我可以将XML数据成功上传到我的服务，但是，尝试做使用JSON同样是失败。该POJO是：如何将JSON请求发布到Jersey REST服务？

@XmlRootElement 
public class Address { 
    String city; 
    String zip; 
    //Getters & setters... 
}

服务资源是：

@POST 
@Produces("application/json") 
public Address fix(Address a) { 
    return a; 
}

我做一个POST如下：

POST /AcmeWeb/svc/simple HTTP/1.1 
Content-Length: 30 
Content-Type: application/json; charset=UTF-8 

{"city":"Miami","zip":"33130"}

服务器与400错误的请求响应。我搜索了互联网，但没有发现发布JSON的好例子。任何帮助表示赞赏。谢谢。

添加@Consumes("application/json")注释您fix()方法。

更新：这工作对我来说：

资源的方法：

@POST 
@Produces("application/json") 
@Consumes("application/json") 
public Address post(Address addr) { 
    return addr; 
}

Address类：

@XmlRootElement 
public class Address { 
    public String city; 
    public String zip; 
}

这是我送的要求：

Accept application/json 
Content-Type application/json; charset=UTF-8 

{"city":"Miami","zip":"33130"}

这就是我得到的回应：

{"city":"Miami","zip":"33130"}

没有帮助。我甚至增加了一个接受头：接受：应用/ JSON，文本/ JavaScript中，*/*; q = 0.01 – RajV 2012-03-15 17:43:19

这很奇怪，它适用于我。我已经更新了我的答案和我如何实现它。 – 2012-03-15 18:44:49

检查服务器日志以查看服务器端是否存在任何堆栈跟踪。 – 2012-03-15 18:52:04

作为解决方法，您可以在包中创建一个jaxb.properties文件，您的JAXB类（例如地址）位于具有以下内容：

javax.xml.bind.context.factory=com.sun.xml.bind.v2.ContextFactory

这应该告诉WLS使用的，而不是从EclipseLink的一个从JAXB RI（这也是目前在WLS 12C的JAXBContext类的实例）。请记住，这只是一个解决方法。

这真的会导致400错误请求（而不是500服务器错误）还是这是一个不同的问题？我看到你提出了标记EclipseLink的问题。 – Rup 2012-03-20 13:28:55

这仍然是一个问题 - 上述异常导致泽西岛发生400错误请求。 – 2012-03-20 14:29:34

实际上，看起来像Jersey Json xml读取器，它使用JAXB取消XML事件来读取JSON有一些问题（请参阅最后一个堆栈跟踪）。即这个问题可能与Jersey的JsonXmlStreamReader而不是MOXy有关。 – 2012-03-20 15:23:45
