使用ExceptionMapper记录客户端错误

https://github.com/dropwizard/dropwizard/blob/master/dropwizard-jersey/src/main/java/io/dropwizard/jersey/errors/LoggingExceptionMapper.java

这个实现的问题是,即使它同时捕获4**和5**个错误,它也只记录5**个错误。

我需要实现ExceptionMapper,这样LoggingExceptionMapper就不用了,我的CustomExceptionMapper同时记录客户端和服务器的错误。

我想知道我的应用程序如何知道它需要使用CustomExceptionMapper而不是Dropwizard类?

另外,将CLIENT\u ERROR添加到if条件中,以注销所有错误是否足够?

@Override
public Response toResponse(E exception) {
    // If we're dealing with a web exception, we can service certain types of request (like
    // redirection or server errors) better and also propagate properties of the inner response.
    if (exception instanceof WebApplicationException) {
        final Response response = ((WebApplicationException) exception).getResponse();
        Response.Status.Family family = response.getStatusInfo().getFamily();
        if (family.equals(Response.Status.Family.REDIRECTION)) {
            return response;
        }
        if (family.equals(Response.Status.Family.SERVER_ERROR) || family.equals(Response.Status.Family.CLIENT_ERROR) {
            logException(exception);
        }

        return Response.fromResponse(response)
                .type(MediaType.APPLICATION_JSON_TYPE)
                .entity(new ErrorMessage(response.getStatus(), exception.getLocalizedMessage()))
                .build();
    }

还是有更好的办法?
