如何使带有JSON数据的post ajax调用到Jersey休息服务?

我已经通过此链接.但这并没有帮助我.

I have been through this link. but this did not helped me out.

我正在使用jersey lib v1.17.1. 我的球衣休息服务:

I am using jersey lib v1.17.1. My jersey rest service:

@POST @Consumes({MediaType.APPLICATION_JSON}) @Produces({MediaType.APPLICATION_JSON}) @Path("/post1") public ResponseBean post1(@QueryParam("param1")String param1) { return ResponseFactory.createResponse(param1, "TEST", "TEST", null, true); }

URL是:/test/post1

我的ajax呼叫:

var d = {"param1":"just a dummy data"}; $.ajax({ type : "POST", url : "localhost:7070/scl/rs/test/post1", contentType :"application/json; charSet=UTF-8", data : d, dataType : "json" }) .done(function(data){ console.log(data); }) .fail(function(data){ console.log(data); });

它打到了我的休息服务，但是作为param1，我总是得到空值.另一种解决方案是添加带有@XMLRootElement的JavaBean，它将把Java对象封送/解组到json，反之亦然，但是我不想使用它. 是否有任何方法可以发布数据并使用诸如@QueryParam之类的适当注释接收数据? 请帮助

It hits to my rest service but as param1 I am alway getting null value. The alternate solution is to add JavaBean with @XMLRootElement which will marshal/unmarshal the java object to json and vice versa, but I do not want to use this. Is there any way to post data and receive it using appropriate annotation like @QueryParam or something like that ? Please help

推荐答案

您的服务器端代码应如下所示:

Your server-side code should be like this:

@POST @Consumes({MediaType.APPLICATION_JSON}) @Produces({MediaType.APPLICATION_JSON}) @Path("/post1") public ResponseBean post1(Data param1) { return ResponseFactory.createResponse(param1, "TEST", "TEST", null, true); }

其中，Data是一个用@XmlRootElement注释的(POJO)类，它对应于客户端将发送的JSON数据(即，具有带有getter和setter的param1字段). JAX-RS实现会将POST的正文解组为Data的实例.

where Data is a (POJO) class annotated with @XmlRootElement and corresponds to the JSON data what your client will send (ie, have a param1 field with getter and setter). The JAX-RS implementation will unmarshall the body of the POST into an instance of Data.

@QueryParam批注用于在(通常)GET请求中检索查询参数.查询参数是问号(?)之后的参数.例如:当处理以下请求时，@QueryParam("start") String start将映射为1:GET foo/bar?start=1，但这不是您要使用的AFAICS.

@QueryParam annotation is used ot retrieve the query params in a (usually) GET requests. Query params are the params after the question mark (?). Eg: @QueryParam("start") String start will map be set to 1 when the following request is processed: GET foo/bar?start=1, but this is not what you're doing in your case, AFAICS.
