Spring Boot 1.x版本，升级2.x之后，报如下异常： ### Cause: java.lang.IllegalArgumentException: jdbcUrl is required with driverClassName...$Proxy68.selectOne(Unknown Source) 此异常的主要原因是：在1.x配置数据源配置为： spring.datasource.url= spring.datasource.driverClassName...spring.datasource.username= spring.datasource.password= spring.datasource.driver-class-name= 也就是说url替换为jdbc-url，driverClassName
