spring开机调用API返回错误时间

Question

my mapping code here:

@Column(name = "movie_name", nullable = false, length = 100)
private String name;

@Column(name = "director", nullable = false, length = 50)
private String director;

@Column(name = "cast", nullable = false, length = 255)
private String cast;

@Column(name = "duration_start", nullable = false)
@CreationTimestamp
@Temporal(TemporalType.TIME)
@JsonFormat(shape = JsonFormat.Shape.STRING, pattern = "HH:mm:ss", timezone = "Asia/Vietnam")
private Date durationStart;

@Column(name = "duration_end", nullable = false)
@CreationTimestamp
@Temporal(TemporalType.TIME)
private Date durationEnd;

@Column(name = "genre", nullable = false)
private String genre;

@CreationTimestamp
@Temporal(TemporalType.TIMESTAMP)
@Column(name = "release_date", nullable = false, length = 50)
private Date releaseDate;

@Column(name = "language", nullable = false, length = 100)
private String language;

@Column(name = "rated", nullable = false, length = 100)
private String rate;

@Column(name = "poster", length = 1000, nullable =  false)
private String poster;

@OneToMany(mappedBy = "movie")
private List<Ticket> listTickets;

}`

i have data time like that image:

but when i call api it return like here: it is seem that the time is automatically plus 8 hours when i call api (int duration_start)

i am trying to add annotation @jsonformat and fix server utc in application.properpties but it is seem that it is not effective

Answer 1

It may be that the time zone is inconsistent with the spring json constructor you are using. First, you can print the time obtained by the backend to see if it is the same as the frontend. If not, you need to configure the springboot file. add content:

spring:
  jackson:
    time-zone: (Your Timezone)
    date-format: yyyy-MM-dd HH:mm:ss

If the two are consistent, you need to check whether the time stored in the database is the same as the correct time. If there is a gap between the time of the database and the actual time, you need to edit the file in the spring database:

spring.datasource.url=jdbc:mysql://11.1.1.1111:3306/database?characterEncoding=utf-8&serverTimezone=GMT%2B8

Database configuration followed by

 &serverTimezone=GMT%2B8

("%2B" means "+","%2D" means "-",choose your Timezone)

You can also check whether the time zone of the database is correct. If not, you can set the database time zone (but not recommended, it will affect the old data)

set global time_zone = '+7:00';

set time_zone = '+7:00';

Or add it in springboot's application.properties

spring.jackson.date-format=yyyy-MM-dd HH:mm:ss
spring.jackson.time-zone= GMT+7
