正如我从 Scalikejdbc 的文档中了解到的那样，如果我想要进行交易，我需要通过会话。像这样：
class FooBarService {
val fooDao = new FooDao
val barDao = new BarDao
def fooBar(): Unit = {
DB localTx { session =>
fooDao.foo(new Foo())
barDao.bar(new Bar())
}
}
}
class FooDao {
def foo(foo: Foo)(implicit session: DBSession): Unit = {
sql"""bla bla bla"""
}
}
class BarDao {
def bar(bar: Bar)(implicit session: DBSession): Unit = {
sql"""bla bla bla"""
}
}
而那件事让我明确地依赖于 Scalikejdbc。我不想在我的领域特征中依赖 Scalike。我想要的是这样的：
class FooBarService {
val fooDao = new FooDao
val barDao = new BarDao
def fooBar(): Unit = {
// My wrapper which abstract and is not dependent on Scalike or other library
MyWrapper.withinTransaction {
fooDao.foo(new Foo())
barDao.bar(new Bar())
}
// or at least not to pass session to daos
DB withinTransaction {
fooDao.foo(new Foo())
barDao.bar(new Bar())
}
}
}
class FooDao {
def foo(foo: Foo): Unit = {
sql"""bla bla bla"""
}
}
class BarDao {
def bar(bar: Bar): Unit = {
sql"""bla bla bla"""
}
}
有没有办法进行交易并且不依赖会话和类签名中的scalike？
