.一个栗子: var BicycleShop = function(){}; BicycleShop.prototype = { sellBicycle : function( model ){ var bicycle; switch(model){ case "The Speedster": bicycle = new Speedster(); break; case "The Lowrider": bicycle = new Lowrider(); break;…
Spring预备知识(适合中小型项目) 作用:集成和管理其他框架 工厂模式: A a = new A( ); 将类所要创建的对象写入工厂,统一进行管理 package com.spring; public class TestSimpleFactoryPattern { /** * 工厂模式:利用工厂模式调用两个类 */ public static void main(String[] args) { // TODO Auto-generated method stub CarFactory…
简单工厂模式是由一个方法来决定到底要创建哪个类的实例, 而这些实例经常都拥有相同的接口. 这种模式主要用在所实例化的类型在编译期并不能确定, 而是在执行期决定的情况. 说的通俗点,就像公司茶水间的饮料机,要咖啡还是牛奶取决于你按哪个按钮. e.g. var BicycleShop = function(){}; BicycleShop.prototype = { sellBicycle : function( model ){ var bicycle; switch( model ){ case…
