## 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。
