spring boot 2.x + mybatis 整合

1. JDBC 连接 mysql 5.0

driverClassName=com.mysql.jdbc.Driver
url=jdbc:mysql://localhost:3306/test?useUnicode=true&characterEncoding=utf8&useSSL=false
username=root
password=

2. JDBC 连接 mysql 6.0 以上

注意：

连接mysql 8.0需要使用新的驱动，否则会出现异常

新：com.mysql.cj.jdbc.Driver
旧：com.mysql.jdbc.Driver

异常信息：

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.

需要设置时区等信息

jdbc:mysql://127.0.0.1:3306/test?serverTimezone=Asia/Shanghai&useUnicode=true&characterEncoding=utf8&useSSL=false

异常信息：

java.sql.SQLException: The server time zone value 'Öйú±ê׼ʱ¼ä' is unrecognized or represents more than one time zone. You must configure either the server or JDBC driver (via the serverTimezone configuration property) to use a more specifc time zone value if you want to utilize time zone support.
