spring.datasource.url=jdbc:mysql://abc:3306/abcd?useUnicode=true&characterEncoding=utf8
很常规地配置了这个mysql的url后发现报错
Wed Oct 24 14:59:16 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.
根据介绍，这里需要在URL那指定useSSL这个属性
然后试过useSSL=true
spring.datasource.url=jdbc:mysql://abc:3306/abcd?useUnicode=true&characterEncoding=utf8&useSSL=true
又报了一个错

没有证书设置的话这里只能useSSL=false
最终这样设置
spring.datasource.url=jdbc:mysql://abc:3306/abcd?useUnicode=true&characterEncoding=utf8&useSSL=false
