网站交互用什么做推广app拿返佣的平台
概述
今天在做一个前后端分离项目时,发现从后端获取的时间与从数据库获取的时间相差八个小时，最终排查后发现由于Springboot使用本地时区导致，修改SpringBoot时区后解决
环境
- MySQL8
- SpringBoot
原因排查
发现从后端获取的数据总是比前端快八个小时
- ajax返回数据
{"uid": 1,"username": "malong","password": "2","name": "mal","birthday": "2019-06-18T16:00:00.000+00:00","sex": "女","telephone": "010-1234567","email": "malong@163.com","status": "Y","code": "57fdfb86837c4888b12411b89eba00e1","isadmin": null,"deptId": 3,"deptName": null
}
- 日志打印user对象
2024-06-05 15:18:15.717 WARN 6632 --- [nio-8080-exec-7] x.wrywebsite.controller.UserController : User(uid=1, username=malong, password=2, name=mal, birthday=Wed Jun 19 00:00:00 CST 2019, sex=女, telephone=010-1234567, email=malong@163.com, status=Y, code=57fdfb86837c4888b12411b89eba00e1, isadmin=null, deptId=3, deptName=null)
发现后端时区为CST，前端为UTC
解决方案
修改Spring Boot时区，在项目启动前增加代码
@SpringBootApplication
@MapperScan("xyz.wrywebsite.dao")
public class UserServerApplication {public static void main(String[] args) {TimeZone.setDefault(TimeZone.getTimeZone("UTC"));SpringApplication.run(UserServerApplication.class, args);}}
修改后，再次启动，前后端date数据一致，问题解决
