log4j2 - spring 和 log4j2 的问题

问题描述

将 log4j 从 1.2.17 升级到 2.13.3 时遇到以下问题。问题是spring boot bean的时候告诉我没有引入log4j jar。
发现是因为spring默认使用commons-logging作为日志输出，所以引入了jar slf4j和log4j-slf4j-impl，但是问题还是没有解决

这是错误详细信息：

解决方案

您需要添加 log4j-1.2-api jar。但是， com.ui.frame.logger.LoggerFactory.getUtilLog 可能无法正常运行，因为它仍然被编码为使用 Log4j 1，所以虽然添加 jar 可以解决这个问题，但之后您仍然可能会看到更多。
