IFactory.java类（顶层）
- 1 package AbstractFactory;

- 3 public interface IFactory {
- 4 public IUser createUser();
- 5 public IDepartment createDepartment();
- 6 }
IUser.java类（下层）
- 1 package AbstractFactory;

- 3 public interface IUser {
- 4 public void insert();
- 5 public void getById();
- 6 }
IDepartment.java类（下层）
- 1 package AbstractFactory;
- 2
- 3 public interface IDepartment {
- 4 public void insert();
- 5 public void getDepartmentById();
- 6 }
AccessUser.java类
- 1 package AbstractFactory;
- 2
- 3 public class AccessDepartment implements IDepartment {
- 4
- 5 @Override
- 6 public void insert() {
- 7 // TODO Auto-generated method stub
- 8 System.out.println("insert department into sqlserver.");
- 9 }
- 10
- 11 @Override

- 13 // TODO Auto-generated method stub
- 14 System.out.println("get department in ssqlserver by id.");
- 15 }
- 16
- 17 }
AccessDepartment.java类
- 1 package AbstractFactory;
- 2
- 3 public class AccessDepartment implements IDepartment {
- 4
- 5 @Override
- 6 public void insert() {
- 7 // TODO Auto-generated method stub
- 8 System.out.println("insert department into sqlserver.");

- 11 @Override

- 13 // TODO Auto-generated method stub
- 14 System.out.println("get department in ssqlserver by id.");
- 15 }

AccessFactory.java类
- 1 package AbstractFactory;

FactoryTest.java类
- 1 package AbstractFactory;
- 2
- 3 public class FactoryTest {
- 4
- 5 public static void main(String[] args) {
- 6 // TODO Auto-generated method stub
- 7 IFactory factory = new AccessFactory();
- 8 IUser user = factory.createUser();
- 9 IDepartment department = factory.createDepartment();
- 10 user.insert();
- 11 user.getById();
- 12 department.insert();
- 13 department.getDepartmentById();
- 14 }
- 15
- 16 }
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
