项目最初使用hikari连接池，直到周三发生连接泄露，切换druid连接池，使用druid默认配置，最大连接为8，

在监控中看到逻辑打开连接数大于逻辑关闭连接数（一般发生在两万次左右），查看连接堆栈信息如下：

原以为业务逻辑执行完之后连接未关闭，执行aop日志时由于spring事务传播特性设置为Propagation.NOT_SUPPORTED，此时会重新获取一条新连接，然后线程之间发生死锁

@OverRide
@transactional(propagation = Propagation.NOT_SUPPORTED)
public void addLog(LogDto logDto) {
try{
StackTraceElement[] stackTrace = Thread.currentThread().getStackTrace();
log.error(stackTrace.toString());
logMapper.addLog(logDto);
}catch(Exception e){
log.error("系统内部日志记录失败，日志内容：{}，错误原因：{}", logDto.getSuser(), logDto.toString(), e.getStackTrace());
}
后来通过实验，业务逻辑执行完后就关闭了连接

暂时没有排查头绪，求帮助，生产环境出现的，挺急

我用的1.2.6版本的druid的starter，高并发下同样遇到这个问题
