Is gormDB instance thread safe?

[Kevinzhezhe]

Is gormDB thread safe?
I just created a global variable like below code.
then can I share this db *gormDB in multiple threads?
I probably use sqlite, pg, and mysql

var db *gormDB
func init() {
var err error
// 连接到 SQLite 数据库
_, datadir := utils.GetDir()
db, err = gorm.Open(sqlite.Open(path.Join(datadir, "xsxl")), &gorm.Config{})
if err != nil {
utils.Error(fmt.Sprintf("failed to connect to database: %v", err))
return
}

// 自动迁移 Journal 和 JournalContent 实体
err = db.AutoMigrate(&definitions.Journal{}, &definitions.JournalContent{}, &definitions.JournalComment{})
if err != nil {
	utils.Error(fmt.Sprintf("failed to migrate database: %v", err))
}

}
