1、使用 idea

2、工程使用 nacos(1.4.0) 做配置中心

3、seata(spring-cloud-starter-alibaba-seata 2.2.3.RELEASE) 使用 db 模式，seata 数据库在本地电脑 mysql 上

4、配置中心有测试、开发两个配置，测试环境的业务数据库在阿里云，开发环境的业务数据库在本地电脑

5、使用 devtools 自动热启动

6、框架版本是 spring boot(2.2.5.RELEASE)、spring cloud(Hoxton.SR3)、spring cloud aibaba(2.2.1.RELEASE)

问题来了：

当使用测试环境配置时，一切正常OK。但是，切换到开发环境（测试环境和开发环境的配置只有数据库的地址不一样，其他的都一模一样）时，一旦触发 devtools 自动重启时，seata 就一直抛出异常

异常内容：
