Mybatis集成MySQL驱动不兼容之 Data truncation: Truncated incorrect DOUBLE value --BUG

Springboot 2.1版本，则数据库默认依赖是mysql8.0，使用旧的配置可能造成mybatis Update无效！，

解决方案两种：1 把项目mysql依赖版本降低，指定数据库为5.X，2升级MySQL为8.0以上即可！

-------------------------------------------------------------------------------------------------------------------

1、开始我怀疑是事务没有提交，但是简单的例子中增删改查，除开update，其余几个接口都是正常的，我也加上了事务配置，问题依然，

2尝试切换数据库update失效问题消失，顿开，数据库连接驱动是该bug的原因，

3总结：遇到意外情况，检查逻辑是否有误？无误，则检查依赖是否不妥，而后密切关注依赖版本与外界组件兼容支持情况，等升级依赖版本，或者外界组件尤其需要注意！
