com.mysql.jdbc.Driver 和 com.mysql.cj.jdbc.Driver的区别
调试代码时,发现错误:
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.
在网上巴拉巴拉发现,原来:
com.mysql.jdbc.Driver
是 mysql-connector-java 5中的;com.mysql.cj.jdbc.Driver
是 mysql-connector-java 6中的。
1、JDBC连接Mysql5 com.mysql.jdbc.Driver:
spring:
# 数据库连接
datasource:
url: jdbc:mysql://192.168.1.1:3306/demo?useUnicode=true&characterEncoding=utf8&useSSL=false
username: root
password: 123456
driver-class-name: com.mysql.jdbc.Driver
2、JDBC连接Mysql6 com.mysql.jdbc.Driver,需要指定时区serverTimezone:
spring:
# 数据库连接
datasource:
url: jdbc:mysql://192.168.1.1:3306/demo?serverTimezone=UTC&useUnicode=true&characterEncoding=utf8&useSSL=false
# 在设定时区的时候,如果设定serverTimezone=UTC,会比中国时间早8个小时,如果在中国,可以选择Asia/Shanghai或者Asia/Hongkong,例如:
# ?serverTimezone=Shanghai&useUnicode=true&characterEncoding=utf8&useSSL=false
username: root
password: 123456
driver-class-name: com.mysql.cj.jdbc.Driver
