Gorm sql.NullTime时区问题 - Nineya|java/go/python

这是我的表结构

type PharrCompany struct {
    Id        int32        `json:"id" gorm:"primarykey;column:id"`
    CompanyId int32        `json:"company_id" gorm:"column:company_id"`
    BeginTime sql.NullTime `json:"begin_time" gorm:"column:begin_time"`
    EndTime   sql.NullTime `json:"end_time" gorm:"column:end_time"`
}

func (*PharrCompany) TableName() string {
    return "pharr_company"
}

我创建一条数据

       dns := fmt.Sprintf(
        "%s:%s@tcp(%s:%d)/%s?charset=utf8mb4&parseTime=True&loc=Local",
        user,
        password,
        host,
        port,
        dbName,
    )
    db, _ := gorm.Open(
        mysql.Open(dns),
        &gorm.Config{
            Logger: logger.Default.LogMode(logger.Info),
        },
    )
    beginTimeStr := "2021-01-01 00:00:00"
    parseBeginTime, _ := time.Parse("2006-01-02 15:04:05", beginTimeStr)
    beginTime := sql.NullTime{Time: parseBeginTime, Valid: true}
    db.Create(
        &PharrCompany{
            CompanyId: 1,
            BeginTime: beginTime,
            EndTime:   sql.NullTime{Valid: false},
        },
    )

这是打印的创建语句 Gorm sql.NullTime时区问题

可是数据存储的却是 2021-01-01 08:00:00

Gorm sql.NullTime时区问题

我本地的时区是Asia/Shanghai 我只有使用一下方式才能得到正确的结果

        loc, err := time.LoadLocation("Asia/Shanghai")
    if err != nil {
        return
    }
    parseBeginTime, err := time.ParseInLocation("2006-01-02 15:04:05", beginTimeStr, loc)
    if err != nil {
        return
    }

parseBeginTime, _ := time.Parse("2006-01-02 15:04:05", beginTimeStr)

这边没有带时区的话，入库的时候会当做 2021-01-01 00:00:00，是UTC时区。要改成 parseBeginTime, _ := time.ParseInLocation("2006-01-02 15:04:05", beginTimeStr, time.Local)
