我要评论报错
启动有报错，但不影响使用，本着不放过任何一个错误的原则来解决下
报错代码：
严重: unable to process jar entry [meta-inf/versions/9/module-info.class] from jar [jar:file:/g:/maven/repository/org/apache/logging/log4j/log4j-api/2.16.0/log4j-api-2.16.0.jar!/] for annotations

解决
因为不影响使用，所以我们可以在启动tomcat时需要跳过检查的jar包。
通过tomcat.util.scan.standardjarscanfilter.jarstoskip参数实现
打开如下目录文件
tomcat\conf\catalina.properties
tomcat.util.scan.standardjarscanfilter.jarstoskip节点增加log4j-api-2.16.0.jar
重启启动tomcat无报错。
总结
以上为个人经验，希望能给大家一个参考，也希望大家多多支持代码网。
