springboot+mybatis框架连接，新版本8.0mysql的配置

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-jdbc</artifactId>
        </dependency>
        <dependency>
            <groupId>mysql</groupId>
            <artifactId>mysql-connector-java</artifactId>
            <version>8.0.11</version>
        </dependency>            

2、application.properties

spring.datasource.driver-class-name = com.mysql.cj.jdbc.Driver
spring.datasource.url = jdbc:mysql://xxx.xxx.x.xxx:3306/aiwmcx?useUnicode=true&characterEncoding=utf8&useSSL=false&autoReconnect=true&serverTimezone=UTC

驱动Driver推荐用：com.mysql.cj.jdbc.Driver，不用com.mysql.jdbc.Driver

注意：新版8.0的mysql驱动的url必须设置时区，即：serverTimezone=UTC，否则会报如下错误：
