Threads are going to be renewed over time to try and avoid a probable memory leak. 2014-7-13 1:37:44 org.apache.catalina.startup.HostConfig deployDirectory

2、錯誤原因

? ? ? 通過這句“Caused by: java.lang.ClassNotFoundException: org.objectweb.asm.ClassVisitor”可知，是缺少有關asm jar包

3、解決的方法

? ? ?將“asm-3.3.1.jar”拷貝到lib文件夾下，又一次啟動服務
