Tomcat 解决“At least one JAR was scanned for TLDs yet contained no TLDs”问题

1. 在tomcat/conf/logging.properties文件的未尾添加： 

org.apache.catalina.startup.TldConfig.level = FINE
org.apache.jasper.compiler.TldLocationsCache.level = FINE
org.apache.jasper.servlet.TldScanner.level = FINE

２. 重启tomcat

3.  cd到tomcat/logs目录下执行命令

egrep "No TLD files were found in \[file:[^\]+\]" /var/usr/tomcat/logs/catalina.out -o | egrep "[^]/]+.jar" -o | sort | uniq | sed -e 's/.jar/.jar,\\/g' > ./skips.txt

４. 在当前目录下找到skips.txt,把内容拷贝至tomcat/conf/catalina.properties文件中的 “org.apache.catalina.startup.TldConfig.jarsToSkip=” 处，保存该文件

５. 把步骤１的三行注释掉

６.（最好先删除 tomcat/work 下的所有内容）重启 Tomcat
