谁见过啊。在以前的电脑上没的出现 。在win7下出现了这个问题。是版本的问题吗？
是这个包 handsome-ipaddress-bin的问题吗？

------解决方案--------------------
java.lang.NoClassDefFoundError: org/apache/log4j/Level
log4j的包没导入。
------解决方案--------------------
* log4j-1.2.15.jar 这个包 或者更高版本的...
------解决方案--------------------
错误提示是要org/apache/log4j/Level这个包
你导的这个handsome-ipaddress-bin 里面有这个路径的包吗
而且他提示的是这个Level类找不到 
你虽然有log4j的包 但是由于版本问题 里面并没有Level类 你直接到你的jar包里找看有没有

------解决方案--------------------
重新导入1.2以上的jar包 重新部署 安逸
