问题根源
这个VerifyError的核心原因是类路径中同时存在Log4j 1.x的核心类和Log4j 2.x的log4j-1.2-api桥接包，导致类定义冲突：
org.apache.log4j.bridge.LogEventAdapter是Log4j 2.x桥接包中的类，它试图继承Log4j 1.x的LoggingEvent类并覆盖其getTimeStamp()方法。- 但Log4j 1.x的
LoggingEvent中getTimeStamp()是final方法，不允许被覆盖，类加载时触发验证错误。
从你的类路径看，log4jdbc-1.2.jar大概率包含了Log4j 1.x的核心类，或者存在其他未列出的Log4j 1.x依赖，引发了冲突。
解决方案
1. 移除冲突的Log4j 1.x类
- 检查并删除类路径中所有Log4j 1.x的核心jar（如
log4j-1.2.x.jar）。 - 替换
log4jdbc-1.2.jar为兼容Log4j 2.x
