Loading class com.mysql.jdbc.Driver’. This is deprecated. The new driver class iscom.mysql.cj.jdbc.Driver’. The driver is automatically registered via the SPI and manual loading of the driver class is generally unnecessary.
原因就是旧版的driver不兼容新版的driver(6.0以上)了, 需要改变以下几点(粗体)
driverClassName=com.mysql.cj.jdbc.Driver //旧版是com.mysql.jdbc.Driver
url=jdbc:mysql://localhost:3306/test?serverTimezone=Asia/Shanghai&useUnicode=true&characterEncoding=utf8&useSSL=false
//需要指定时区serverTimezone:
username=root
password=123456
