MySql 数据表中数据时间字段差8小时

1 问题

java应用程序写入MySQL的数据时间字段小8小时

2 查看MySQL服务器时区配置

mysql> show variables like '%time_zone';
+------------------+--------+
| Variable_name    | Value  |
+------------------+--------+
| system_time_zone | CST    |
| time_zone        | SYSTEM |
+------------------+--------+
mysql> select now(), curtime();
+---------------------+-----------+
| now()               | curtime() |
+---------------------+-----------+
| 2024-10-17 16:32:33 | 16:32:33  |
+---------------------+-----------+
1 row in set (0.00 sec)

3 修改java应用连接mysql的url

添加serverTimezone=Asia/Shanghai，比如jdbc连接如下：

jdbc:mysql://localhost:3306/db_name?useUnicode=true&characterEncoding=UTF-8&useSSL=false&serverTimezone=Asia/Shanghai
