最近我遇到了一个引起我兴趣的建筑师模式.

所以,我有一个构建实体的EntityBuilder,但它没有返回实体.这是方法签名：

public void build();

相反,在build()方法内部,它将创建的新对象Entity传递给CacheImplementation实例以存储它.
注意：CacheImpl是在构建器的构造函数中注入的.

public void build(){
    //create new entity
    cacheImplementation.add(entity);
}

这听起来像是最佳做法吗？

稍后编辑0

public interface EntityBuilder {

    void setProperty0(PropertyObject propertyObject0);
    void setProperty1(PropertyObject propertyObject1);
    void setProperty2(PropertyObject propertyObject2);
    //...

    void build();
}

public class EntityBuilderImpl implements EntityBuilder {

    PropertyObject propertyObject0;
    PropertyObject propertyObject1;
    PropertyObject propertyObject2;
    //...

    // setters for all properties
    @Override
    public void build(){
        //create new entity
        cacheImplementation.add(entity);
    }
}

构建器按以下方式使用：

public class EntityProcessor{
  private EntityBuilderFactory entityBuilderFactory;//initialized in constructor

  void process(EntityDetails entityDetails){
       EntityBuilder entityBuilder = this.entityBuilderFactory.getNewEntitytBuilder();
       //..
       // entityBuilder.set all properties from entityDetails
       entityBuilder.build();
  }
}

注意：cacheImpl实例仅将实体存储在List<>中.每N秒访问一次.
