-------------------------------------------------------------------以上是POM.xml配置---------------------------------------------------------------------------

application.properties配置

spring.datasource.username=xxxx
spring.datasource.password=xxxx
spring.datasource.url=jdbc:mysql://localhost:3306/springdb
spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver

mybatis.mapper-locations=classpath:mapper/*.xml

这句话你得按照你的路径配置，也就是你的.xml在哪个位置，你就怎么配置

---------------------------------------------------------------以上是application.properties配置---------------------------------------------------------------

这样配置一下就OK了。下面说下****配置

一定要注意这两个属性，

红框第一个属性，如果为true 那么会生成两份 mybatis的xml语句在xml文件中

红框第二个属性，因为现在mysql的驱动已经更新到了8.x+版本，如果不写这一句，是识别不了主键的那么，就会发生代码生成找不到一些主键的问题。

驱动链接也同样的变化为com.mysql.cj.jdbc.Driver 而不是 com.mysql.jdbc.Driver
