一、大致构造
1、导演者类
2、建造抽象类
3、产品抽象类
4、产品具体类
5、建造具体类
二、代码（建造模式，相当于将一堆零件组装成一个对象）
1、建造抽象类
Builder.java
package com.builderModel;
public interface Builder {
public void BuildPart1();
public void BuildPart2();
public Product getProduct();
}
2、产品标识类
package com.builderModel;
public interface Product {
}
3、具体产品类
Article.java
package com.builderModel;
public class Article implements Product {
private String title;
private String content;
public String getTitle() {
return title;
}
public void setTitle(String title) {
this.title = title;
}
public String getContent() {
return content;
}
public void setContent(String content) {
this.content = content;
}
@Override
public String toString() {
return "Article [title=" + title + ", content=" + content + "]";
}
}
AutoMessage.java
package com.builderModel;
public class AutoMessage implements Product {
private String from;
private String content;
public String getFrom() {
return from;
}
public void setFrom(String from) {
this.from = from;
}
public String getContent() {
return content;
}
public void setContent(String content) {
this.content = content;
}
@Override
public String toString() {
return "Message [from=" + from + ", content=" + content + "]";
}
}
4、具体产品构造者
ArticleBuilder.java
package com.builderModel;
public class ArticleBuilder implements Builder {
Article article = new Article();
@Override
public void BuildPart1() {
article.setTitle("hello");
}
@Override
public void BuildPart2() {
article.setContent("world");
}
@Override
public Product getProduct() {
return article;
}
}
AutoMessageBuilder.java
package com.builderModel;
public class AutoMessageBuilder implements Builder {
private AutoMessage message = new AutoMessage();
@Override
public void BuildPart1() {
message.setFrom("客户");
}
@Override
public void BuildPart2() {
message.setContent("你的网页出错了");
}
@Override
public Product getProduct() {
return message;
}
}
5、导演者类
Director.java
package com.builderModel;
public class Director {
private Builder builder = null;
public Director(Builder builder) {
this.builder = builder;
this.builder.BuildPart1();
this.builder.BuildPart2();
}
public Product getProduct() {
return this.builder.getProduct();
}
}
6、测试类
Test.java
package com.builderModel;
public class Test {
public static void main(String[] args) {
Builder builder = new AutoMessageBuilder();
Director director = new Director(builder);
AutoMessage autoMessage = (AutoMessage) director.getProduct();
System.out.println(autoMessage.toString());
}
}
