takeaway

For project purposes, @jsonformat does not work when formatting dates using Lombok.

Entity class

import com.fasterxml.jackson.annotation.JsonFormat;
import lombok.Data;

import java.util.Date;

@Data
public class Ts {
    private String id;
    private String name;
    private Integer age;
    @JsonFormat(pattern = "yyyy-MM-dd HH:mm:ss", timezone = "GMT+8")
    private Date cTime;

    @JsonFormat(pattern = "yyyy-MM-dd HH:mm:ss", timezone = "GMT+8")
    private Date insertime;

    @JsonFormat(pattern = "yyyy-MM-dd HH:mm:ss", timezone = "GMT+8")
    private Date updateTime;
}

conclusion

When using Lombok’s defined entity classes, the second letter of the attribute is not capitalized, otherwise duplicate capitalization results will occur (such as cTime, cTime, and cTime data). Uppercase letters except the second letter are supported.
