异常产生环境

SpringBoot项目，配置mysql数据库时产生

异常描述

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.

异常原因

在SpringBoot项目下，没有指定MySQL驱动版本的情况下它自动依赖的驱动是8.0.12很高的版本，这是由于数据库和系统时区差异所造成的，在jdbc连接的url后面加上serverTimezone=GMT即可解决问题

解决办法

spring:
  datasource:
    url: jdbc:mysql://localhost:3306/*****?serverTimezone=UTC
    username: *****
    password: *****
    driver-class-name: com.mysql.jdbc.Driver
