找不到类型为com.sun.jersey.api.json.JSONWithPadding的响应对象的MessageBodyWriter，媒体类型为:application/x-javascript [英] Could not find MessageBodyWriter for response object of type: com.sun.jersey.api.json.JSONWithPadding of media type: application/x-javascript

问题描述

我正在尝试在主干应用程序上使用jsonp.在我的网络服务中，我试图使用Jersey库来使用JSONWithPadding响应.

I'm trying to use jsonp on my backbone application. In my webservice, I'm trying to use the Jersey library to use the JSONWithPadding response.

问题是，似乎不支持"application/x-javascript".

Problem is, looks like the "application/x-javascript" is not supported.

我的代码是:

@GET
@Path("/issues/jsonp")
@Produces("application/x-javascript")
public JSONWithPadding getIssuesJsonp(@Context HttpServletRequest req,
    @PathParam("ppid") String qppid,
    @QueryParam("callback") String callback) {

Principal principal = req.getUserPrincipal();
    String username = principal.getName();

try {
    List<IssueDTO> list = service.getIssuesDTO(username, qppid);
    IssuesResult r = new IssuesResult();
    r.setIssues(list);
    System.out.println("CALLBACK:" + callback);
    return new JSONWithPadding(r,callback);
} catch (Exception e) {
    String message = "Internal Server Error";
    LOG.error(message, e);
    Result r = new Result(PPStatusCode.INTERNAL_SERVER_ERROR, message);
    return new JSONWithPadding(noCache(500, r),callback);
}
}

结果是:

Etat HTTP 500-找不到媒体类型:application/javascript 的响应对象类型为com.sun.jersey.api.json.JSONWithPadding的MessageBodyWriter

Etat HTTP 500 - Could not find MessageBodyWriter for response object of type: com.sun.jersey.api.json.JSONWithPadding of media type: application/javascript

有人可以帮助我吗?

推荐答案

基于堆栈跟踪，看起来JBoss中提供的Resteasy无法从jersey-json.jar中找到您(我想)捆绑在WAR中的JSONWithPaddingProvider . JSONWithPadding是泽西岛特定的课程，如果要使用它，您可以使用2个选项:

Based on the stacktrace it looks like Resteasy provided in JBoss is unable to find JSONWithPaddingProvider from jersey-json.jar which you have (I suppose) bundled in your WAR. JSONWithPadding is Jersey specific class and if you want to use it you have 2 options:

• 按照中的描述，在web.xml中将Jersey库添加到您的WAR中(如果尚未在其中)，并禁用Resteasy.在Jboss AS 7上部署Jersey网络应用程序，以确保您的应用程序将Jersey用作JAX-RS实现
• 将jersey-json.jar添加到JBoss类路径中，以便Resteasy能够找到此jar中的MessageBodyWriter(JSONWithPaddingProvider)

• add Jersey libs to your WAR (if you don't have them there already) and disable Resteasy in web.xml as described in Deploying a Jersey webapp on Jboss AS 7 to make sure your application uses Jersey as JAX-RS implementation
• add jersey-json.jar to the JBoss classpath so Resteasy is able to find MessageBodyWriter (JSONWithPaddingProvider) located in this jar
