分析：百度一大堆，都是什么mapper扫不到什么的。。。。，在jar包里都有，最后只能慢慢看日志
最后发现，com.baomidou.mybatisplus.core.exceptions.MybatisPlusException: java.net.UnknownHostException: wdd: wdd: System error
at com.baomidou.mybatisplus.core.toolkit.Sequence.getLocalHost，
去查Sequence源码，就是在服务器上getLocalHost获取不到。
想了一下，自己的阿里云服务器，可能是wdd（或者是阿里云的实例名）连接不上

处理：（1）修改阿里云的实例名hostnamectl set-hostname wdd
（2）查看实例名：hostname
（3）配置host
自己服务器ip 实例名
（4）重启服务，ok
