题目

某网络游戏程序中有如下几个类。
Equip类（装备类）

public class Equip {//装备
    private String name;//装备名称
    private String type;//装备类型，头盔，铠甲等
    private Long speedPlus;//速度增效
    private Long attackPlus;//攻击增效
    private Long defencePlus;//防御增效

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public String getType() {
        return type;
    }

    public void setType(String type) {
        this.type = type;
    }

    public Long getSpeedPlus() {
        return speedPlus;
    }

    public void setSpeedPlus(Long speedPlus) {
        this.speedPlus = speedPlus;
    }

    public Long getAttackPlus() {
        return attackPlus;
    }

    public void setAttackPlus(Long attackPlus) {
        this.attackPlus = attackPlus;
    }

    public Long getDefencePlus() {
        return defencePlus;
    }

    public void setDefencePlus(Long defencePlus) {
        this.defencePlus = defencePlus;
    }

    @Override
    public String toString() {
        return "Equip{" +
                "name='" + name + '\'' +
                ", type='" + type + '\'' +
                ", speedPlus=" + speedPlus +
                ", attackPlus=" + attackPlus +
                ", defencePlus=" + defencePlus +
                '}';
    }
}

Player类(玩家类 )

public class Player { //玩家
    private Equip armet;//头盔
    private Equip loricae;//铠甲
    private Equip boot;//靴子
    private Equip ring;//指环
    
    //升级装备
    public void updateEquip(Equip equip){
        if ("指环".equals(equip.getType())){
            System.out.println(ring.getName()+"升级为"+equip.getName());
            this.ring = equip;
        }
    }

    public Equip getArmet() {
        return armet;
    }

    public void setArmet(Equip armet) {
        this.armet = armet;
    }

    public Equip getLoricae() {
        return loricae;
    }

    public void setLoricae(Equip loricae) {
        this.loricae = loricae;
    }

    public Equip getBoot() {
        return boot;
    }

    public void setBoot(Equip boot) {
        this.boot = boot;
    }

    public Equip getRing() {
        return ring;
    }

    public void setRing(Equip ring) {
        this.ring = ring;
    }

    @Override
    public String toString() {
        return "Player{" +
                "armet=" + armet +
                ", loricae=" + loricae +
                ", boot=" + boot +
                ", ring=" + ring +
                '}';
    }
}

玩家的装配

装备 战神头盔 连环锁子甲 波斯追风靴 蓝魔指环
速度增效 2 6 8 8
攻击增效 4 4 2 12
防御增效 6 15 3 2

（1）编写程序代码，以如下格式输出蓝魔指环的属性。

蓝魔指环[速度增效:8;攻击增效:12;防御增效:2]

（2）使用aop实现如下功能。

现举行免费升级指环的活动，可以免费将任意指环升级为”紫色梦幻”指环，新的装备名称为”紫色梦幻+原指环名”，而且将在原指环的基础上再加上6点攻击，6点防御。
提示：
使用前置通知增强，判断要升级的装备是否为指环，如果是，则需按需求修改传入的参数的名称，以及攻击增效和防御增效属性。

使用xml
applicationContext.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:aop="http://www.springframework.org/schema/aop"
       xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/aop https://www.springframework.org/schema/aop/spring-aop.xsd">

    <bean class="com.work1.Player">

        <property name="ring" ref="ring"/>
    </bean>
    <bean id="armet" class="com.work1.Equip">
        <property name="name" value="战神头盔"/>
        <property name="type" value="头盔"/>
        <property name="speedPlus" value="2"/>
        <property name="attackPlus" value="4"/>

        <property name="speedPlus" value="6"/>
        <property name="attackPlus" value="4"/>
        <property name="defencePlus" value="15"/>
    </bean>
    <bean id="boot" class="com.work1.Equip">

        <property name="type" value="靴子"/>
        <property name="speedPlus" value="8"/>
        <property name="attackPlus" value="2"/>
        <property name="defencePlus" value="3"/>
    </bean>
    <bean id="ring" class="com.work1.Equip" scope="prototype">
        <property name="name" value="蓝魔指环"/>
        <property name="type" value="指环"/>
        <property name="speedPlus" value="8"/>
        <property name="attackPlus" value="12"/>

    </bean>
    <bean class="com.work1.BeforeBoost" id="aspect"/>
    <aop:config>
        <aop:pointcut id="myPointCut" expression="execution(* com.work1.Player.updateEquip(..))"/>
        <aop:aspect ref="aspect">
            <aop:before method="ringBeforeAdvice" pointcut-ref="myPointCut"/>
        </aop:aspect>
    </aop:config>
</beans>

切面类

@Component
public class BeforeBoost {

    public void myPointCut(){

    }

    public void ringBeforeAdvice(JoinPoint joinPoint){
        //获取目标对象方法参数
        Object[] args = joinPoint.getArgs();
        // 使用数组
        List<Object> equips =  Arrays.asList(args);
        /*System.out.println(equips);*/
        
        Object object = equips.get(0);
        Equip equip= (Equip) object;
        if(equip.getType().equals("指环")){
            System.out.println("获取传入目标方法的参数对象" + equip);
            String name = "紫色梦幻" + equip.getName();
            equip.setName(name);
            equip.setAttackPlus(equip.getAttackPlus()+6);
            equip.setDefencePlus(equip.getDefencePlus()+6);
//            System.out.println(equip.getAttackPlus());
            System.out.println("修改后的参数对象"+equip);
        }
        System.out.println("----------------------------------------");
    }
}

测试类

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = "classpath:applicationContext.xml")
public class EquipTest {
    @Autowired
    private Player player;

    @Autowired
    @Qualifier("ring")
    private Equip equip;
    @Test
    public void test1() {
        Equip ring = player.getRing();
        System.out.println(ring);
        player.updateEquip(equip);
        System.out.println(player);
    }
}

结果是

使用注解
applicationContext2.xml

切面类

@Aspect

    public void myPointCut(){

        //获取目标对象方法参数
        Object[] args = joinPoint.getArgs();
        // 使用数组
        List<Object> equips =  Arrays.asList(args);
        /*System.out.println(equips);*/
        
        Object object = equips.get(0);
        Equip equip= (Equip) object;
        if(equip.getType().equals("指环")){
            System.out.println("获取传入目标方法的参数对象" + equip);
            String name = "紫色梦幻" + equip.getName();
            equip.setName(name);
            equip.setAttackPlus(equip.getAttackPlus()+6);
            equip.setDefencePlus(equip.getDefencePlus()+6);
//            System.out.println(equip.getAttackPlus());
            System.out.println("修改后的参数对象"+equip);
        }
        System.out.println("----------------------------------------");

测试类

@RunWith(SpringJUnit4ClassRunner.class)
