Threads are going to be renewed over time to try and avoid a probable memory leak. 2014-7-10 23:12:23 org.apache.catalina.startup.HostConfig deployDirectory
2、错误原因
通过这个“Caused by: java.lang.ClassNotFoundException: org.apache.commons.lang3.StringUtils”,可知这个缺少commons-lang3-3.1.jar包
3、解决的方法
将“commons-lang3-3.1.jar”复制到文件夹lib文件夹
