JAVA设计模式之【建造者模式】
2024-08-31 12:15:09
建造者模式
建造者模式为客户端返回的不是一个简单的产品，而是一个由多个部件组成的复杂产品
角色
Builder抽象建造者
buildPartX
getResult
ConcreteBuilder具体建造者
Product产品角色
Director指挥者
复杂对象
指包含多个成员属性的对象，它们称为部件或零件
比如汽车，包含方向盘、发动机、轮胎等
1.角色类
package Builder;
/**
* Created by e550 on 2016/10/1.
*/
public class Actor {
private String type; // 角色
private String sex; // 性别
private String face; // 脸型
private String costume; // 服装
private String hairstyle; // 发型
public void setType(String type) {
this.type = type;
}
public void setSex(String sex) {
this.sex = sex;
}
public void setFace(String face) {
this.face = face;
}
public void setCostume(String costume) {
this.costume = costume;
}
public void setHairstyle(String hairstyle) {
this.hairstyle = hairstyle;
}
public String getType() {
return this.type;
}
public String getSex() {
return this.sex;
}
public String getFace() {
return this.face;
}
public String getCostume() {
return this.costume;
}
public String getHairstyle() {
return this.hairstyle;
}
}
2.角色构造抽象类
package Builder;
/**
* Created by jim on 2016/10/3.
*/
abstract class ActorBuilder {
protected Actor actor = new Actor();
public abstract void buildType();
public abstract void buildSex();
public abstract void buildFace();
public abstract void buildCostume();
public abstract void buildHairstyle();
public Actor createActor() {
return actor;
}
}
3.角色构造具体类，英雄角色
package Builder;
/**
* Created by e550 on 2016/10/3.
*/
public class HeroBuilder extends ActorBuilder{
public void buildType() {
actor.setType("英雄");
}
public void buildSex() {
actor.setSex("男");
}
public void buildFace() {
actor.setFace("英俊");
}
public void buildCostume() {
actor.setCostume("盔甲");
}
public void buildHairstyle() {
actor.setHairstyle("飘逸");
}
}
天使角色
package Builder;
/**
* Created by e550 on 2016/10/3.
*/
public class AngelBuilder extends ActorBuilder{
public void buildType() {
actor.setType("天使");
}
public void buildSex() {
actor.setSex("女");
}
public void buildFace() {
actor.setFace("漂亮");
}
public void buildCostume() {
actor.setCostume("白裙");
}
public void buildHairstyle() {
actor.setHairstyle("披肩长发");
}
}
恶魔角色
package Builder;
/**
* Created by e550 on 2016/10/3.
*/
public class DevilBuilder extends ActorBuilder{
public void buildType() {
actor.setType("恶魔");
}
public void buildSex() {
actor.setSex("妖");
}
public void buildFace() {
actor.setFace("丑陋");
}
public void buildCostume() {
actor.setCostume("黑衣");
}
public void buildHairstyle() {
actor.setHairstyle("光头");
}
}
4.角色控制器
package Builder;
/**
* Created by e550 on 2016/10/3.
*/
public class ActorController {
public Actor construct(ActorBuilder ab) {
Actor actor;
ab.buildType();
ab.buildSex();
ab.buildFace();
ab.buildCostume();
ab.buildHairstyle();
actor = ab.createActor();
return actor;
}
}
5.客户端执行
package Builder;
/**
* Created by e550 on 2016/10/3.
*/
public class Client {
public static void main(String args[]) {
ActorBuilder ab;
ab = new AngelBuilder();
ActorController ac = new ActorController();
Actor actor;
actor = ac.construct(ab);
System.out.println("类型:" + actor.getType());
System.out.println("性别:" + actor.getSex());
System.out.println("面容:" + actor.getFace());
System.out.println("服装:" + actor.getCostume());
System.out.println("发型:" + actor.getHairstyle());
}
}
执行结果
类型:天使
性别:女
面容:漂亮
服装:白裙
发型:披肩长发
