CentOS7/Linux下Tomcat-8啓動報錯解決

錯誤信息tomcat是在掃描org.jaxen.util.AncestorAxisIterator這個類的時候報錯，所以解決方法有兩個：

一、忽略tomcat啓動時掃描jar包

tomcat8.0:
打開在tomcat的conf目錄裏面catalina.properties的文件，
tomcat.util.scan.StandardJarScanFilter.jarsToSkip=
改爲tomcat.util.scan.DefaultJarScanner.jarsToSkip=,*

tomcat8.5:
打開在tomcat的conf目錄裏面catalina.properties的文件，
tomcat.util.scan.StandardJarScanFilter.jarsToSkip=
改爲tomcat.util.scan.StandardJarScanFilter.jarsToSkip=,*

二、更新jar包

更好的解決方案是更新jar包，更新Jaxen-1.1.6和dom4j-1.6.1兩個jar包
