IFactory.java类（顶层）

package AbstractFactory;

public interface IFactory {
    public IUser createUser();
    public IDepartment createDepartment();
}

---

IUser.java类（下层）

package AbstractFactory;

public interface IUser {
    public void insert();
    public void getById();
}

---

IDepartment.java类（下层）

package AbstractFactory;

public interface IDepartment {
    public void insert();
    public void getDepartmentById();
}

---

AccessUser.java类

package AbstractFactory;

public class AccessDepartment implements IDepartment {

    @Override
    public void insert() {
        // TODO Auto-generated method stub
        System.out.println("insert department into sqlserver.");
    }

    @Override
    public void getDepartmentById() {
        // TODO Auto-generated method stub
        System.out.println("get department in ssqlserver by id.");
    }

}

---

AccessDepartment.java类

package AbstractFactory;

public class AccessDepartment implements IDepartment {

    @Override
    public void insert() {
        // TODO Auto-generated method stub
        System.out.println("insert department into sqlserver.");
    }

    @Override
    public void getDepartmentById() {
        // TODO Auto-generated method stub
        System.out.println("get department in ssqlserver by id.");
    }

}

---

AccessFactory.java类

package AbstractFactory;

public class AccessDepartment implements IDepartment {

    @Override
    public void insert() {
        // TODO Auto-generated method stub
        System.out.println("insert department into sqlserver.");
    }

    @Override
    public void getDepartmentById() {
        // TODO Auto-generated method stub
        System.out.println("get department in ssqlserver by id.");
    }

}

---

FactoryTest.java类

package AbstractFactory;

public class FactoryTest {

    public static void main(String[] args) {
        // TODO Auto-generated method stub
        IFactory factory = new AccessFactory();
        IUser user = factory.createUser();
        IDepartment department = factory.createDepartment();
        user.insert();
        user.getById();
        department.insert();
        department.getDepartmentById();
    }

}

说明：

需要一个顶级接口、两个下层接口、两个实现下层接口的具体实现的类、1个顶层接口具体实现的类（用于创建下层接口具体实现的类）、主方法调用

IFactory factory = new AccessFactory();向上转型1次（顶层接口）（顶层接口中有两个抽象方法，下层的向上转型是同级别的）
IUser user = factory.createUser();向上转型1次（下层接口）
IDepartment department = factory.createDepartment();向上转型1次（下层接口）
user.insert();最后调用子类方法返回结果
user.getById();最后调用子类方法返回结果
department.insert();最后调用子类方法返回结果
department.getDepartmentById();最后调用子类方法返回结果
