严重: The web application [/FirstSSH] created a ThreadLocal with key of type [com.sun.faces.util.Util$1] (value [com.sun.faces.util.Util$1@11872a8]) and a value of type [java.util.HashMap] (value [{com.sun.faces.patternCache={ = }}]) but failed to remove it when the web application was stopped. Threads are going to be renewed over time to try and avoid a probable memory leak.

2、错误原因

     通过这句可知。“Caused by: java.lang.ClassNotFoundException: org.apache.commons.logging.LogFactory”。缺少Struts2中的一个jar

3、解决的方法

     将“commons-logging-1.1.3.jar”拷贝到lib文件夹文件夹下
