解決

因?yàn)椴挥绊懯褂?，所以我們可以在啟?dòng)Tomcat時(shí)需要跳過(guò)檢查的jar包。

通過(guò)tomcat.util.scan.StandardJarScanFilter.jarsToSkip參數(shù)實(shí)現(xiàn)

打開(kāi)如下目錄文件

tomcat\conf\catalina.properties

tomcat.util.scan.StandardJarScanFilter.jarsToSkip節(jié)點(diǎn)增加log4j-api-2.16.0.jar

重啟啟動(dòng)tomcat無(wú)報(bào)錯(cuò)。

總結(jié)

以上為個(gè)人經(jīng)驗(yàn)，希望能給大家一個(gè)參考，也希望大家多多支持腳本之家。
