Just just solve the problem of time format, suddenly found time to check out and stored in the database of the time difference of eight hours
Because Mysql use the system default time zone, the East eight districts.
But I handled the business district UTC when logic in the link database
spring.datasource.url=jdbc:mysql://localhost/laidoulailareset? characterEncoding=utf8&useSSL=true&serverTimezone=UTC
So there will be time difference of eight hours
Modify way: serverTimezone = Asia / Shangha
spring.datasource.url=jdbc:mysql://localhost/laidoulailareset? characterEncoding=utf8&useSSL=true&serverTimezone=Asia/Shanghai
