SpringBoot项目访问MySQL时区错误问题
错误信息
Unable to obtain connection from database: 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.

原因分析
我们可以用MySQL的命令查看目前服务器的time_zone配置：
show global variables like '%time_zone%';
show variables like '%time_zone%';
| Variable_name | Value |
|---|---|
| system_time_zone | |
| time_zone | SYSTEM |
默认情况下system_time_zone没有配置，但是time_zone却指向它，可能系统会有个默认的时区值，看错误信息是乱码，并不清楚到底是什么时区，所以报错。
解决方法
要么修改MySQL的连接字符串，要么修改MySQL的默认配置指定定一个时区，下面的几种方式任选一种即可。
注意：配置的时区不一样会影响插入的日期数据的值
-
修改MySQL连接字符串，添加serverTimezone=xxx来实现。
- 配置连接
serverTimezone=UTC或者配置成：serverTimezone=Asia/Shanghai或者配置：serverTimezone=GMT%2B8。 - 连接字符串：jdbc:mysql://localhost:3306/user_db?useUnicode=true&characterEncoding=UTF-8&serverTimezone=Asia/Shanghai
- 配置连接
-
修改MySQL默认配置文件
- 修改MySQL的配置文件，Windows下路径：C:\ProgramData\MySQL\MySQL Server 8.0\my.ini
- 在
[mysqld]区域添加：default-time-zone="+8:00"
-
用命令改MySQL配置，格式：
set global time_zone = timezoneset global time_zone='+8:00' set global time_zone='Asia/Shanghai'
