Look at the code of the database connection pool:In real life, China's income tax is divided into enterprise income tax, foreign-invested enterprises or foreign-invested enterprises income tax and personal income tax. For these three types of income tax, each is calculated in a different way. Personal income tax has a personal income tax calculation method, while enterprise income tax has its corresponding calculation method. If we do not adopt the policy mode to realize such a requirement, we will define an income tax class, which has an attribute to identify the type of income tax and a CalculateTax () method to calculate the tax. In this method, we need to judge the tax type and calculate the income tax for different tax types through if-else statements. Such an implementation can indeed solve this scenario, but such a design is not conducive to expansion. If the system needs to add an income tax in the later period, it has to go back and modify the CalculateTax method to add an additional judgment statement, which clearly violates the principle of "open-closed". At this time, we can consider using the strategic mode to solve this problem. Since the tax method is the changing part of this scenario, we can naturally think of abstracting the tax method at this time, which is also the essence of the implementation of the strategic mode.在盛唐背景下，那个时代是人类、妖族并存的，然而，人类、妖族的混血儿李玄的出现打破了暂时平静的世界，一场大的阴谋正在滋生，藏在暗处的人蠢蠢欲动，期间，李玄、妖族女间谍苏犹怜、幻世恋人龙薇儿之间的也出现了情感的纠葛……彼时，已经是拯救人类的英雄的李玄却陷入了两难的境地，人族败，母亲死，妖族败，他便为人族叛徒。最终，李玄战胜石星御，破坏长安大阵，释放了被人族囚禁的妖族，一场战争被化解，人妖两族获得了暂时和平，但代价惨重，守护人妖两族，重建长安的责任落在了李玄身上。On March 5, 2014, during the media open day of the Second Session of the 12th National People's Congress, a female reporter did not win the opportunity to interview and left tears of regret after the meeting.　　品酒师许致因丈夫出轨而离婚，知名电视人雷达阴差阳错地帮助许致父亲、鸟研所研究员许北洋惩治了前女婿，自己却爱上许致，却因此遭到对女儿婚事变得格外谨慎的许北洋的残酷围剿。许北洋二女许葳和被父亲看做轻浮不成熟的男友王闯私自领证结婚，又搞出假怀孕事件，许北洋大发雷霆，亲自监督二人造人。法国的外甥女许诺回国找男友，先找了一个比许北洋还大一岁的老头，接着又和一个纨绔富二代罗士雄谈婚论嫁。按下葫芦起来瓢，让丧妻多年本就不擅长处理家务事的许北洋苦不堪言。女儿是父亲前世的小情人，女儿的出嫁让许北洋“醋”意满满，心碎无痕。为了女儿们的终身幸福，许北洋决意严格把关择婿事宜，想出各种刁钻办法考验三个女婿。雷达不堪其重，和王闯、罗士雄组成女婿联盟对抗岳父！一番博弈，许北洋终于理解和接纳了三个女婿，翁婿和解。Dogs go and do singing and stuff.
