用mysql没有问题，就是一直控制台出黄子提示，大佬们有没有办法让这个不显示

ConsoleSpamFix  可以尝试用这个插件进行屏蔽

检查mysql的地址格式是否正确
address: 127.0.0.1
database: luckperms
username: root
password: 123456

Possibly consider using a shorter maxLifetime value.
这一行就是提示，这是hikari连接池的一个参数，请在lp修改 maxLifetime 为更小的值
如果lp中没有可供修改的地方，就需要退而求其次修改mysql中对应的参数
如果不是实在没有办法，切忌一上来就使用spamfix等屏蔽报错的插件，典型的头痛医嘴，只不过是掩盖了问题，增加了风险，对实际技能成长毫无帮助

我先试试，这个提示是一直再刷，隔几分钟刷好多

格式完全没有问题，服务器内正常使用，权限组也有效果，mysql格式不对服务器就没法加载

刚刚搜了一下 应该是插件的maxlifetime和mysql的wait_timeout两个参数之间需要有合理的比例关系
这是我搜到的，你也可以百度看看
