Python设计模式(8)-抽象工厂

# coding=utf-8


这种方式反倒把事情做复杂了   可取之处在于有了更高层次的抽象

class IEmployee:
    def insert_employee(self):
        pass


class ICompany:
    def insert_company(self):
        pass


# mysql版本的数据库访问
class EmployeeMysql(IEmployee):
    def insert_employee(self):
        print "插入员工mysql数据库"


class CompanyMysql(ICompany):
    def insert_company(self):
        print "插入公司mysql数据库"


class EmployeeMSSQL(IEmployee):
    def insert_employee(self):
        print "插入员工sqlserver数据库"


class CompanyMSSQL(ICompany):
    def insert_company(self):
        print "插入公司sqlserver数据库"


class IFactory:
    def insert_employee(self):
        pass

    def insert_company(self):
        pass


class FactoryMySQL(IFactory):
    def insert_employee(self):
        temp = EmployeeMysql()
        return temp

    def insert_company(self):
        temp = CompanyMysql()
        return temp


class FactoryMSSQL(IFactory):
    def insert_employee(self):
        temp = EmployeeMSSQL()
        return temp

    def insert_company(self):
        temp = CompanyMSSQL()
        return temp


if __name__ == "__main__":
    factory = FactoryMSSQL()
    employee = factory.insert_employee()
    insert_company = factory.insert_company()
    employee.insert_employee()
    insert_company.insert_company()
