无法找到类型为:com.sun.jersey.api.json的MessageBodyWriter。媒体类型的JSONWithPadding: application/x-javascript

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.

我正在尝试在我的主干应用程序中使用jsonp。在我的webservice中，我尝试使用Jersey库来使用JSONWithPadding响应。

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

问题是，看起来不支持“application/x-javascript”。

My code is :

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);
}
}

And the result is:

结果是:

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

Etat HTTP 500 -无法找到类型为:com.sun.jersey.api.json的MessageBodyWriter。媒体类型的JSONWithPadding: application/javascript

Can someone help me ?

谁能帮帮我吗?

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:

基于stacktrace，看起来JBoss提供的Resteasy无法从jerchy -json找到JSONWithPaddingProvider。jar，我想是你在战争中捆绑的。JSONWithPadding是Jersey特定的类如果你想使用它你有两个选项:

• 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
• 在您的战争中添加泽西岛的libs(如果您还没有的话)，并在web中禁用Resteasy。如在Jboss上部署Jersey webapp as 7中所描述的xml，以确保应用程序使用Jersey作为JAX-RS实现
• add jersey-json.jar to the JBoss classpath so Resteasy is able to find MessageBodyWriter (JSONWithPaddingProvider) located in this jar
• 添加jersey-json。jar到JBoss类路径，这样Resteasy才能找到位于这个jar中的MessageBodyWriter (JSONWithPaddingProvider)

RestEasy also has the JacksonJsonpInterceptor already - if you are using Guice with RestEasy, you can bind(JacksonJsonpInterceptor.class) in an appropriate module, otherwise you will should configure it as normal for RestEasy (see https://docs.jboss.org/resteasy/docs/1.1.GA/userguide/html/Interceptors.html section 29.6):

RestEasy也已经拥有了JacksonJsonpInterceptor——如果你使用的是带有RestEasy属性的Guice，你可以在一个适当的模块中绑定(JacksonJsonpInterceptor.class)，否则你应该将它配置为RestEasy的正常属性(参见https://docs.jboss.org/restey/docs/docs/1.1.1.1.1.user29./interceps.html):

they can be listed in the resteasy.providers context-param in web.xml or returned as a class or object in the Application.getClasses() or Appication.getSingletons() method.

它们可以列在resteasy上。提供者context-param在web。在Application.getClasses()或appic.getsingletons()方法中作为类或对象返回。
