JAX-RS CXF异常包装 [英] JAX-RS CXF Exception wrapping

问题描述

我想向CXF(2.6.1)添加一个ExceptionMapper，它不仅可以传达响应代码，还可以以有效载荷格式(以我现在使用的JSON形式)运送异常.

I would like to add an ExceptionMapper to CXF (2.6.1) which not only communicates the Response code, but also ships the exception in the payload format (I'm using JSON for now).

@Provider
public class CustomExceptionMapper
        implements
            ExceptionMapper<MyException>
{
...
@Override
public Response toResponse(MyException mex)
{
//I need something here which can convert mex object to JSON and ship it in response
// I want this to be de-serialized on client

//the following returns the status code
return Response.status(Response.Status.BAD_REQUEST).build();
}
...
}

有没有办法做到这一点?

Is there a way to do this ?

推荐答案

您可能需要使用@Produces将对象序列化为JSON，例如:

You may need to use @Produces to serialize your object to JSON like:

@Produces(MediaType.APPLICATION_JSON)

然后是return Response.ok().entity(OBJECT).build();

测试服务的方式:

ClientConfig config = new DefaultClientConfig();
Client client = Client.create(config);
WebResource service = client.resource(getBaseURI());
ClientResponse response = service.path(ADDRESS).type("application/json").get(ClientResponse.class);
String s = response.getEntity(String.class);
System.out.println(s); 

private static URI getBaseURI() {
        return UriBuilder.fromUri(SERVER ADDRESS).build();
}
