1. 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.
java.lang.NullPointerException:
2. Loading class `com.mysql.jdbc.Driver'. This is deprecated. The new driver class is `com.mysql.cj.jdbc.Driver'. The driver is automatically registered
via the SPI and manual loading of the driver class is generally unnecessary.
java.lang.NullPointerException
驱动改为com.mysql.cj.jdbc.Driver
3. Mysql jdbc连接驱动改为com.mysql.cj.jdbc.Driver 报错java.lang.NullPointerException:
