Question

这是我的服务 -

@GET
    @Path("{id}/json")
    @Produces("application/json")
    public Response getImageByIdJson(@PathParam("id") int imageId) {
        //return this.getInageById(imageId);
        List<Image> imageList = null;

        try {
            imageList = intlxBusiness.getAllImage();
        } catch (SQLException e) {
            e.printStackTrace();
        }

        Image returnImage = null;
        for (Image image : imageList) {

            if (image.getImageId() == imageId)
                returnImage = image;
        }

        // Creates a ResponseBuilder
        ResponseBuilder builder = new ResponseBuilderImpl();
        // Sets the header of the return data
        builder.header("content-type", "application/json");
        // Sets the response code as a 200
        builder.status(Response.Status.OK);
        // Allows Cross Domain Requests from any origin
        builder.header("Access-Control-Allow-Origin", "*");
        // Adds your result data to the Response
        builder.entity(returnImage);
        // Creates the Response
        return builder.build();
    }

这是我的ajax电话 -

<head>
    <meta charset="utf-8">
    <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
    <script type="text/javascript">
    $.ajax({
        type:"GET",
        url: "http://localhost:8888/IntellixWebApi/intellixservices/activeimage/1/json",
         headers : {Accept : "application/json","Access-Control-Allow-Origin" : "*"}
        dataType:"json",
        crossDomain: true,
        success: function(data){
            alert(data);
        },
        error: function(msg){
            alert("ERROR! \n" + msg);
        }
    });

</script>

这是我的回复屏幕截图 -

Image for Response

但是没有数据。

当我通过浏览器打电话时;然后我得到以下回复 -

在Json

{"Image-Id":1,"Image-Name":"Visakha Star","Image-Url":"F:/Recieved File/vishaka.jpg","Image-Description":"Description for Star"}

在Xml中 -

<Images Image-Id="1" debug="true">
<script id="FirebugLite" firebugIgnore="true" extension="Chrome"/>
<Image-Name>Visakha Star</Image-Name>
<Image-Url>F:/Recieved File/vishaka.jpg</Image-Url>
<Image-Description>Description for Star</Image-Description>
</Images>

请告诉我哪里错了。该服务将用于CORS。我在服务方法中添加了所需的信息。

EDIT ---

如果我使用这个ajax代码 -

$.ajax({
  type:"GET",
    url: "XXXX",

    cache: false,
    async: false,
    crossDomain: true,
    jsonp: true,
    jsonpCallback: "callback",
    contentType: "application/json; charset=utf-8",
    dataType: "jsonp", 

    success: function(data){
        alert(data);
    },
    error: function(jqXHR, textStatus, errorThrown){alert('fail by event '+errorThrown)}
});

然后我得到了回复，但看了下面的图片 -

Response Pivture

响应xml是正确的。

由于 Kumar Shorav

用于泽西休息服务的Ajax客户端返回成功响应但没有值
