MySQL8的数据库，8.0.11驱动的逆向工程的坑的解决方法

如果您使用的是Connector / J的8.x版，您可能会注意到生成器尝试为MySql信息模式（sys，information_schema，performance_schema等）中的表生成代码。这可能不是您想要的！ 要禁用此行为，请将属性“nullCatalogMeansCurrent = true”添加到JDBC

下面颜色标准的就是8.0.11驱动容易漏掉的，

driverClass="com.mysql.cj.jdbc.Driver"

connectionURL="jdbc:mysql://localhost:3306/logistics?useUnicode=true&characterEncoding=utf8

&serverTimezone=GMT&nullCatalogMeansCurrent = true"
