Jersey异常映射器不处理资源构造器中的异常

Question

I have the following Exception Mapper for my jersey-server:

@Provider
public class ExceptionResponseMapper implements ExceptionMapper<Throwable> {

    Logger logger = Logger.getLogger(ExceptionResponseMapper.class);

    @Override
    public Response toResponse(Throwable e) {
        log.error(e);
        Response response = Response.status(500)
                    .entity(e)
                    .build();

        return response;
    }
}

I register this provider with manually with config.register(ExceptionResponseMapper.class);

The Exception Mapper works perfectly fine for the exceptions thrown in my REST resource classes, except for exceptions in the constructor.

Eg.

@Path("/MyResource")
public class MyResource {

    public MyResource() {
        throw new RuntimeException();
    }
}

will not invoke the Exception Mapper. How can I handle this case of exceptions?

当您通过Spring或CDI创建资源时，我的猜测是Jersey Context还没有准备好（如果您使用的是DI框架）。
