mysql的驱动类com.mysql.jdbc.Driver过时了，需要用com.mysql.cj.jdbc.Driver代替

springboot项目整合mybatis，配置文件如下：

server:
  port: 8081
mybatis:
  config-location: classpath:mybatis/mybatis-config.xml   #mybatis配置文件所在路径
  type-aliases-package: com.yuanqiao.entities     #所有entity别名类所在包
  mapper-locations: classpath:mybatis/mapper/*.xml
spring:
  application:
    name: swaggerdemo
  datasource:
    type: com.alibaba.druid.pool.DruidDataSource
    driver-class-name: com.mysql.jdbc.Driver
    url: jdbc:mysql://localhost:3306/springboot?useUnicode=true&characterEncoding=UTF-8&useJDBCCompliantTimezoneShift=true&useLegacyDatetimeCode=false&serverTimezone=UTC
    username: root
    password: 123456
    dbcp2:
      min-idle: 5         #数据库连接池的最小维持连接数
      initial-size: 5      #初始化连接数
      max-total: 5            #最大连接数
      max-wait-millis: 200      #等待连接获取的最大超时时间

做sql查询的时候，提示com.mysql.jdbc.Driver已经弃用了。

 

Creating a new SqlSession
SqlSession [org.apache.ibatis.session.defaults.DefaultSqlSession@5540e55e] was not registered for synchronization because synchronization is not active
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.
