Answer 1

应该是你的日志包导入错了或者是重复了，你检查下

Answer 2

是不是你缺少日志jar包或者是日志jar包冲突啊，你没检查一下吗？

Answer 3

由于安装QTP引起的。
将环境变量里的：
_classload_hook
_JAVA_OPTIONS
IBM_JAVA_OPTIONS
JAVA_TOOL_OPTIONS
删掉，即可解决该问题

Answer 4

在你执行的时候，源文件加上包名执行试试。

Answer 5

java.lang.NoClassDefFoundError: com/opensymphony/xwork2/util/logging/LoggerFactory
看下这个日志包是不是加载，或者是不是加载冲突？
