蓝色的C就是创建型模式 - 绿色的B就是行为型模式 - 橙色的S就是结构型模式 ![Image](https://pub-f29bf2b53160470c9a85250116509a24.r2.dev/post/2020-03-14-she-ji-mo-shi-mei-shi-jian-xue-yi-tu-dai-ni-gao-ding-23-zhon/004-fdcfe998.png) ### 责任链模式 ![Image](https://pub-f29bf2b53160470c9a85250116509a24.r2.dev/post/2020-03-14-she-ji-mo-shi-mei-shi-jian-xue-yi-tu-dai-ni-gao-ding-23-zhon/005-645fa31f.png) ### 命令模式 ![Image](https://pub-f29bf2b53160470c9a85250116509a24.r2.dev/post/2020-03-14-she-ji-mo-shi-mei-shi-jian-xue-yi-tu-dai-ni-gao-ding-23-zhon/006-a3db9d0c.png) ### 解释器模式 ![Image](https://pub-f29bf2b53160470c9a85250116509a24.r2.dev/post/2020-03-14-she-ji-mo-shi-mei-shi-jian-xue-yi-tu-dai-ni-gao-ding-23-zhon/007-a6dd68e8.png) ### 迭代器模式 ![Image](https://pub-f29bf2b53160470c9a85250116509a24.r2.dev/post/2020-03-14-she-ji-mo-shi-mei-shi-jian-xue-yi-tu-dai-ni-gao-ding-23-zhon/008-24511dc2.png) ### 中介者模式 ![Image](https://pub-f29bf2b53160470c9a85250116509a24.r2.dev/post/2020-03-14-she-ji-mo-shi-mei-shi-jian-xue-yi-tu-dai-ni-gao-ding-23-zhon/009-a62872f9.png) ### 备忘录模式 ![Image](https://pub-f29bf2b53160470c9a85250116509a24.r2.dev/post/2020-03-14-she-ji-mo-shi-mei-shi-jian-xue-yi-tu-dai-ni-gao-ding-23-zhon/010-705aabee.png) ### 观察者模式 ![Image](https://pub-f29bf2b53160470c9a85250116509a24.r2.dev/post/2020-03-14-she-ji-mo-shi-mei-shi-jian-xue-yi-tu-dai-ni-gao-ding-23-zhon/011-ecb68789.png) ### 状态模式 ![Image](https://pub-f29bf2b53160470c9a85250116509a24.r2.dev/post/2020-03-14-she-ji-mo-shi-mei-shi-jian-xue-yi-tu-dai-ni-gao-ding-23-zhon/012-f7865201.png) ### 策略模式 ![Image](https://pub-f29bf2b53160470c9a85250116509a24.r2.dev/post/2020-03-14-she-ji-mo-shi-mei-shi-jian-xue-yi-tu-dai-ni-gao-ding-23-zhon/013-ec5c59c6.png) ### 模版模式 ![Image](https://pub-f29bf2b53160470c9a85250116509a24.r2.dev/post/2020-03-14-she-ji-mo-shi-mei-shi-jian-xue-yi-tu-dai-ni-gao-ding-23-zhon/014-f16adead.png) ### 访问者模式 ![Image](https://pub-f29bf2b53160470c9a85250116509a24.r2.dev/post/2020-03-14-she-ji-mo-shi-mei-shi-jian-xue-yi-tu-dai-ni-gao-ding-23-zhon/015-3c02557a.jpg) ### 适配器模式 ![Image](https://pub-f29bf2b53160470c9a85250116509a24.r2.dev/post/2020-03-14-she-ji-mo-shi-mei-shi-jian-xue-yi-tu-dai-ni-gao-ding-23-zhon/016-e4230923.png) ### 桥接模式 ![Image](https://pub-f29bf2b53160470c9a85250116509a24.r2.dev/post/2020-03-14-she-ji-mo-shi-mei-shi-jian-xue-yi-tu-dai-ni-gao-ding-23-zhon/017-b006237e.png) ### 组合模式 ![Image](https://pub-f29bf2b53160470c9a85250116509a24.r2.dev/post/2020-03-14-she-ji-mo-shi-mei-shi-jian-xue-yi-tu-dai-ni-gao-ding-23-zhon/018-c0d0ae99.png) ### 装饰器模式 ![Image](https://pub-f29bf2b53160470c9a85250116509a24.r2.dev/post/2020-03-14-she-ji-mo-shi-mei-shi-jian-xue-yi-tu-dai-ni-gao-ding-23-zhon/019-94fd6c12.png) ### 门面模式 ![Image](https://pub-f29bf2b53160470c9a85250116509a24.r2.dev/post/2020-03-14-she-ji-mo-shi-mei-shi-jian-xue-yi-tu-dai-ni-gao-ding-23-zhon/020-bcc9155e.png) ### 享元模式 ![Image](https://pub-f29bf2b53160470c9a85250116509a24.r2.dev/post/2020-03-14-she-ji-mo-shi-mei-shi-jian-xue-yi-tu-dai-ni-gao-ding-23-zhon/021-f40c5e77.png) ### 代理模式 ![Image](https://pub-f29bf2b53160470c9a85250116509a24.r2.dev/post/2020-03-14-she-ji-mo-shi-mei-shi-jian-xue-yi-tu-dai-ni-gao-ding-23-zhon/022-7683b2d9.png) ### 抽象工厂模式 ![Image](https://pub-f29bf2b53160470c9a85250116509a24.r2.dev/post/2020-03-14-she-ji-mo-shi-mei-shi-jian-xue-yi-tu-dai-ni-gao-ding-23-zhon/023-75327bf4.png) ### 构造器模式 ![Image](https://pub-f29bf2b53160470c9a85250116509a24.r2.dev/post/2020-03-14-she-ji-mo-shi-mei-shi-jian-xue-yi-tu-dai-ni-gao-ding-23-zhon/024-ba2cc86e.png) ### 工厂方法模式 ![Image](https://pub-f29bf2b53160470c9a85250116509a24.r2.dev/post/2020-03-14-she-ji-mo-shi-mei-shi-jian-xue-yi-tu-dai-ni-gao-ding-23-zhon/025-62cfcc77.png) ### 原型模式 ![Image](https://pub-f29bf2b53160470c9a85250116509a24.r2.dev/post/2020-03-14-she-ji-mo-shi-mei-shi-jian-xue-yi-tu-dai-ni-gao-ding-23-zhon/026-16f1022c.png) ### 单例模式 ![Image](https://pub-f29bf2b53160470c9a85250116509a24.r2.dev/post/2020-03-14-she-ji-mo-shi-mei-shi-jian-xue-yi-tu-dai-ni-gao-ding-23-zhon/027-b88d1fe1.png) 完整PDF文件可以通过这个链接下载： -
