Detected both log4j-over-slf4j.jar AND slf4j-log4j12.jar on the class path, preempting StackOverflow

log4j-over-slf4j和slf4j-log4j12是跟java日志系统相关的两个jar包，当它们同时出现在classpath下时，就可能会引起堆栈溢出异常。异常信息大致如下

java.lang.IllegalStateException: Detected both log4j-over-slf4j.jar AND slf4j-log4j12.jar on the class path, preempting StackOverflowError.

解决方法：

将两个jar包其中一个的依赖移除掉。
