总计0 Hikari Pool，怎么可能？

Question

我有线程系统。太多（数千） 有时我们遇到了数据库瓶颈。 为了分析这个瓶颈，我打开了登录调试模式。我看到了这个：

Hikari装载......

springHikariCP - configuration:

并且在日志结束之前有0个统计数据...

  

池统计信息（总计= 0，活跃= 0，空闲= 0，等待= 0）

     

池统计信息（总计= 0，活跃= 0，空闲= 0，等待= 0）

     

池统计信息（总计= 0，活跃= 0，空闲= 0，等待= 0）

.....

怎么可能呢？ db操作有太多更新，删除，选择，插入执行。什么意思是Total = 0连接？ 难道我们没有正确设置Hikari配置吗？
