Caused by: com.mysql.cj.exceptions.InvalidConnectionAttributeException报错
报错信息：
Caused by: com.mysql.cj.exceptions.InvalidConnectionAttributeException: 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.

这个报错其实是为了使MySQL JDBC驱动程序的5.1.33版本与UTC时区配合使用，必须在连接字符串中明确指定serverTimezone。
修改前的properties配置文件：
#端口
server.port=8080
#jdbc配置
spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver
spring.datasource.url=jdbc:mysql://127.0.0.1:3306/testdb09
spring.datasource.username=root
spring.datasource.password=root
#MyBatis
mybatis.mapper-locations=classpath:com/test/dao/*.xml
mybatis.type-aliases-package=com.test.domain
修改后
#端口
server.port=8080
#jdbc配置
spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver
spring.datasource.url=jdbc:mysql://127.0.0.1:3306/testdb09?useUnicode=true&useJDBCCompliantTimezoneShift=true&useLegacyDatetimeCode=false&serverTimezone=UTC
spring.datasource.username=root
spring.datasource.password=root
#MyBatis
mybatis.mapper-locations=classpath:com/test/dao/*.xml
mybatis.type-aliases-package=com.test.domain
修改
