java重构方式

这里只是简单例子，以动物方式，如何实现重构

1、入口

public class TestMain {
    @Autowired
    private Animal animal;

    @Test
    public void animal(){
        animal.printAnimal();
    }
}

2、判断那个类的执行

@Service
public class Animal {
   @Autowired
   private AnimalFactory animalFactory;

   public void printAnimal(){
       IAnimal pag = animalFactory.getAnimal("pag");
       pag.isAnimal();
   }
}

3、创建一个工厂，返回不同的类

@Service
public class AnimalFactory {
    @Autowired
    private List<IAnimal> isAnimal;

    public IAnimal getAnimal(String animal){
        for(IAnimal iAnimal : isAnimal){
            if(iAnimal.isSupport(animal)){
                return iAnimal;
            }
        }
        throw new RuntimeException("没有该动物类型");
    }
}

4、所需要的接口

public interface IAnimal {
    public boolean isSupport(String adimalType);

    public void isAnimal();
}

5、执行类

public class Dog implements IAnimal {

    @Override
    public boolean isSupport(String adimalType) {
        return adimalType.equals("dog") ? true : false;
    }

    @Override
    public void isAnimal() {
        System.out.println("动物是狗!!!!");
    }
}

@Service
public class Pag implements IAnimal{

    @Override
    public boolean isSupport(String adimalType) {
        return adimalType.equals("pag") ? true : false;
    }

    @Override
    public void isAnimal() {
        System.out.println("动物是猪！！！！");
    }
}
