dubbox是通过什么方式加载RESTEasy的呢

[Elizabeth-sw]

考虑到系统中使用的是dubbox的RESTEasy接口，想利用RESTEasy的ExceptionMappers来做一个全局的异常控制组建，但是写好ExceptionMappers后发现这个类貌似没有被加载，于是跟进dubbox启动过程想看一下dubbox是如何加载RESTEasy的，未果。请教一下各位。

` @Provider public class MyExceptionMappers implements ExceptionMapper {

public static Gson gson = new Gson();
@Override
public Response toResponse(ApiServiceException exception) {
    return Response.status(exception.getErrCode()).tag(exception.getErrMsg()).build();
}

} `
