mysql版本8.0

报错：Wed Dec 19 22:42:12 CST 2018 WARN: Establishing SSL connection without server's identity verification is not recommended. According to MySQL 5.5.45+, 5.6.26+ and 5.7.6+ requirements SSL connection must be established by default if explicit option isn't set. For compliance with existing applications not using SSL the verifyServerCertificate property is set to 'false'. You need either to explicitly disable SSL by setting useSSL=false, or set useSSL=true and provide truststore for server certificate verification.

把：

spring.datasource.url=jdbc:mysql:///:3306/sso?

换成

spring.datasource.url=jdbc:mysql:sso?useUnicode=true&characterEncoding=utf-8&useSSL=false

解决。

springboot使用2.0.8.BUILD-SNAPSHOT版本

mysql驱动包默认是：![20181219224021528.png][]

可以还成8.0.11版本的，中间遇到点坑具体未及时记录了，，，

最终版本的搭配如下：
