我使用struts jar跟随 enter image description here

Answer 1

方法＃1：

对于Tomcat 8，您需要将以下行添加到tomcat/conf/logging.properties，以便Tomcat扫描的jar文件显示在日志中：

org.apache.jasper.servlet.TldScanner.level = FINE

Approache#2:

将此行添加到{CATALINA-HOME}/conf/logging.properties的末尾： org.apache.jasper.level = FINEST
关闭服务器（如果已启动）。
打开控制台并运行（如果是Windows）：

%CATALINA_HOME%\bin\catalina.bat run
享受日志，例如（再次，对于Windows）：

{CATALINA-HOME}/logs/catalina.2015-12-28.log

使用tomcat 8 jre 1.8时struts 2出错
