设计模式 abstractfactory 实现

golang 设计模式 abstractfactory 代码实现

package abstractfactory

import "fmt"

/OrderMainDAO 为订单主记录
type OrderMainDAO interface {
	SaveOrderMain()
}

/OrderDetailDAO 为订单详情纪录
type OrderDetailDAO interface {
	SaveOrderDetail()
}

/DAOFactory DAO 抽象模式工厂接口
type DAOFactory interface {
	CreateOrderMainDAO() OrderMainDAO
	CreateOrderDetailDAO() OrderDetailDAO
}

/RDBMainDAP 为关系型数据库的OrderMainDAO实现
type RDBMainDAO struct{}

/SaveOrderMain ...
func (*RDBMainDAO) SaveOrderMain() {
	fmt.Print("rdb main save\n")
}

/RDBDetailDAO 为关系型数据库的OrderDetailDAO实现
type RDBDetailDAO struct{}

/ SaveOrderDetail ...
func (*RDBDetailDAO) SaveOrderDetail() {
	fmt.Print("rdb detail save\n")
}

/RDBDAOFactory 是RDB 抽象工厂实现
type RDBDAOFactory struct{}

func (*RDBDAOFactory) CreateOrderMainDAO() OrderMainDAO {
	return &RDBMainDAO{}
}

func (*RDBDAOFactory) CreateOrderDetailDAO() OrderDetailDAO {
	return &RDBDetailDAO{}
}

/XMLMainDAO XML存储
type XMLMainDAO struct{}

/SaveOrderMain ...
func (*XMLMainDAO) SaveOrderMain() {
	fmt.Print("xml main save\n")
}

/XMLDetailDAO XML存储
type XMLDetailDAO struct{}

/ SaveOrderDetail ...
func (*XMLDetailDAO) SaveOrderDetail() {
	fmt.Print("xml detail save")
}

/XMLDAOFactory 是XML 抽象工厂实现
type XMLDAOFactory struct{}

func (*XMLDAOFactory) CreateOrderMainDAO() OrderMainDAO {
	return &XMLMainDAO{}
}

func (*XMLDAOFactory) CreateOrderDetailDAO() OrderDetailDAO {
	return &XMLDetailDAO{}
}
