Is there a better way to handle the 'database is locked' in SQLite?

Is there a better way to handle the 'database is locked' in SQLite?

The SQLite is unsupported concurrent and only allows serial to write operation.

Description

I have to add the lock code in the per write operation to prevents the 'database is locked',For example, the following:

var globalLock sync.Mutex

type User struct{
    Name string
    Age int
}
func (u *User) Create(tx *grom.DB){
    globalLock.Lock()
    defer globalLock.Unlock()
    user := User{Name: "xxx", Age: 18}
    tx.Create(&user)
}
type Blog struct{
    Title string
}
func (b *Blog) Create(tx *grom.DB){
    globalLock.Lock()
    defer globalLock.Unlock()
    blog := Blog{Title: "xxx"}
    tx.Create(&blog)
}

I tried to use Hooks to deal with the lock code but found that it was not satisfactory. when the 'tx.Create(&user)' occurs err or panic, AfterCreate doesn't have execute.

func (u *User) BeforeCreate(tx *grom.DB) error{
	globalLock.Lock()
	return nil
}
func (u *User) AfterCreate(tx *grom.DB) error{
	globalLock.Unlock()
	retrun nil
}

You may do this:

		phyDb, err := db.DB()
		phyDb.SetMaxOpenConns(1)
