Java Open source Fresh e-commerce platform-coupon design and architecture (source code can be downloaded)Description: Now the level of e-commerce, whether it is fresh electricity or other e-commerce, and so on, there will be a promotion of this system, the purpose is to increase order volume and visibility and so onSo for Java Open Source Fresh e-commerce platform, we use coupons to promote this way. (The s

front page load is not a lot, the limit of 10, the result is 30% of users can not use the coupon outside the display 2. In order to use, 30% of users will see several pages of coupons, it is also difficult to find Now let's take a logical relationship. 1. Do coupon interaction design to solve those problems? For: The interactive

, 30% of users cannot use out-of-display coupons. 2. for use, 30% of users will see several pages of coupons, which may be difficult to find. Now let's take a look at the logical relationship. 1. What problems do I need to solve in the interactive design of coupons? A: The coupon interaction design is designed to meet the convenience and simplicity of using more

Template methods (Template method) mode Prepare an abstract class, implement part of the logic in the form of concrete methods and concrete constructs, and then declare some abstract methods to force subclasses to implement the remaining logic. Different subclasses can implement these abstract methods in different ways, thus having different implementations of the remaining logic. This is the purpose of th

The template method allows the subclass to redefine certain steps of an algorithm without changing the structure of an algorithm.In l

that the instance must be created automatically and provided externally.　　AdvantagesThere is only one object in system memory, so system resources can be saved, and for some object singleton patterns that need to be created and destroyed frequently, the performance of the system can be improved.　　DisadvantagesThere is no abstraction layer, so the extension is difficult.Too heavy a duty to violate a single duty in a certain procedureTemplate design mo
