使用SpringBoot连接MySQl数据库，
连接代码：
spring.datasource.url = jdbc:mysql://localhost:3306/redis?useUnicode=true&characterEncoding=utf-8 spring.datasource.username = root spring.datasource.password = 123456 spring.datasource.driverClassName =com.mysql.jdbc.Driver
报错代码：
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.
：译文：
请注意:不建议在没有服务器身份验证的情况下建立SSL连接。根据MySQL 5.5.45+、5.6.26+和5.7.6+的要求，如果不设置显式选项，则必须建立默认的SSL连接。您需要通过设置useSSL=false显式地禁用SSL，或者设置useSSL=true并为服务器证书验证提供信任存储
修改：后缀添加安全验证：useSSL=false
spring.datasource.url = jdbc:mysql://localhost:3306/redis?useUnicode=true&characterEncoding=utf-8&useSSL=false
