启动报错

Wed Sep 19 14:30:49 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.

修改url和driverclass（Mysql官网配置连接）

jdbc:mysql://localhost:3306/ajia_store?characterEncoding=UTF8&serverTimezone=Asia/Shanghai，注意中间那个“&”，在xml中这个是读不出的，正确写法将“&”转义“&；”。
