使用MySQL时出现The server time zone value '�й���׼ʱ��' is unrecogni的解决方法

开发数据库相关的项目时，出现如下的异常：org.springframework.jdbc.CannotGetJdbcConnectionException: Failed to obtain JDBC Connection; nested exception is java.sql.SQLException: The server time zone value ‘�й���׼ʱ��’ 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.

解决办法：

根据提示需要在配置数据库的连接信息中，在MySQL的URL后面加上“?serverTimezone=UTC” ，如下所示：

spring:
  devtools:
    restart: true
  datasource:
    type: com.alibaba.druid.pool.DruidDataSource
    driver-class-name: com.mysql.cj.jdbc.Driver
    url: jdbc:mysql://localhost:3306/activiti_demo?characterEncoding=UTF-8&serverTimezone=UTC
    username: root
    password: 123456
