One problem with the factory method pattern is that the creation of the class depends on the factory class, that is to say, if you want to expand the program, you must modify the factory class, which violates the closure principle. Therefore, from the design point of view, there are certain problems, how to solve them? We use the abstract factory mode to create multiple factory classes, so that once new functions need to be added, we can directly add new factory classes without modifying the previous code. Because the abstract factory is not very easy to understand, let's look at the diagram first, and then it is easier to understand with the code.扬州画师郑板桥等众画友进京卖画，与宫廷御画师金敏之结怨。 　　乾隆慕惜日益崛起的扬州画派，微服南下扬州。南巡中乾隆为扬州画师的人品、画品所折服，并钦点郑板桥、金农京考，二人双双高中。但由于金敏之等佞臣作梗，二人不能入朝为官。一晃十年，郑板桥因破译了乾隆出的谜对而被任用为山东潍县知县。乾隆设"千叟宴"施恩天下名人雅士，"扬州八怪"均被邀进京，独不见郑板桥，乾隆龙颜震怒！潍县天灾水患，郑板桥开仓放粮，在抗旨上又添了一条死罪。金敏之又进谗言，但乾隆临乱思辨反将其贬为庶民。官场离乱，郑板桥思前想后写下了"难得糊涂"四字流芳民间……突然一愣，向吕馨说道：你不是很喜欢天启，怎么先关注起司马二的新书？司马二这次气势汹汹，新书肯定不差，所以有点好奇。The above design, as commented above, when executing the Resize method of SmartTest, if a rectangular object is passed in, when the height is greater than the width, the width will be automatically increased until it exceeds the height. However, if a square object is passed in, it will fall into a dead loop. The fundamental reason at this time is that rectangles cannot be the parent class of squares. Since there is a problem, they can be reconstructed so that both of them inherit from quadrilateral classes. The refactoring code looks like this:For the first point, we also often use it in our daily work, such as our Ajax request, which has a success and error callback function, and we can subscribe to Ajax success and error events. We don't care about the state of the object running asynchronously, we only care about success or error when we have to do something of our own ~在罗布奥特曼中，讲述的是和之前的奥特曼完全不一样的剧情。主人公一共有4个，分别是哥哥胜巳和弟弟勇海，女高中生妹妹，和父亲，他们一起经营着一家生活商品店。但是，命运往往都是不可捉摸的。就在看似平静的日子里，实则蕴藏着杀机。有一头怪兽，从天而降。而这头怪兽，也让原本平平淡淡的一家，完全改变了命运。
