如何使带有JSON数据的post ajax调用到Jersey休息服务? [英] How to make post ajax call with JSON data to Jersey rest service?
问题描述
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 : "http://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 http://foo.com/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 http://foo.com/bar?start=1
, but this is not what you're doing in your case, AFAICS.
