項目啟動時警告 Establishing SSL connection without server's identity verification is not recommended

項目啟動時控制台提示警告：

Tue May 14 23:16:10 CST 2019 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.

原因及解決方法提示的很清楚：MySQL在高版本需要指明是否進行SSL(保障Internet數據傳輸安全利用數據加密)

在數據庫URL的配置后面增加一條

spring.datasource.druid.url = jdbc:mysql://127.0.0.1:3319/demo?useUnicode=true&characterEncoding=utf-8&useSSL=false

另外需要注意的是，如果數據庫配置是配置在XML文件中的，那么URL中的 & 符需要進行轉義

<jdbcConnection driverClass="com.mysql.jdbc.Driver"
                connectionURL="jdbc:mysql://127.0.0.1:3319/demo?characterEncoding=utf8&amp;useSSL=false" 
                userId="hello" 
                password="hello@123">
</jdbcConnection>
