我不知道为什么skiplistener不打印简单的日志。我想把跳过的记录记录到一个单独的日志文件中，我想我可以使用mdc.put（）。但我甚至不能打印一个登录控制台不知道发生了什么。我想我遗漏了什么。如果你能帮忙，我将不胜感激。我甚至尝试使用泛型exception.class进行测试，但仍然没有做任何事情。这是我的密码；

            public static final Logger LOG = LogManager.getLogger(LoadDataSkipListener.class);

            @Override
            public void onSkipInRead(Throwable t) {
                LOG.info("ItemWriter:  ");

        //      MDC.put("skipped_users", String.valueOf(item.getUserId())); // I want to log skipped user ids on write

# logging.file={log-name}.log --> WIll this write into a new file ??

只是想知道
为什么它甚至不在控制台中打印？
可以使用注解的mdc写入新文件吗？
提前谢谢！
