microservices design patterns

classes have the same behavior and state.4), ISP (Interface segregation Principle): interface separation principle;Client should not being forced to using a interface if it does not need it. Interface separation rules are designed to work with multiple specific functionsInterface to avoid the redundancy caused by the common interface.5), DIP (Dependency inversion Principle): dependency inversion principle;The high level modules should is depend on the low level modules but the should depend on

"/"; return NewChu ($a,$b); Break; Case"%"; return NewQuyu ($a,$b); Break; } } } $j= Gongchang::d uixiang (3,2, "%");//Test Echo $j->js ();//OutputOutput resultsSecond, the design of six major principles1. The open-close principle is that the design should have good support for the extension, and the modification should be strictly limited.2. On the Richter scale also, the subclass mu

What is the design pattern? In the process of Learning Object-oriented, we will always come into contact with the pattern from time to time! As our predecessors have mentioned, the design model is a summary of people's experience! In software development, we always encounter some reusable components,CodeSo that we can focus on Object-Oriented Reusable Technology. With the development of Reusable Technology,

design mode source code downloadDesign mode source code download1 Template Method modeThe Template method pattern defines the steps of an algorithm and allows a subcategory to provide its practice in one or more steps. Let the subcategory redefine some of the steps in the algorithm without changing the algorithm schema. ----WIKIPEDIAPersonal understandingTemplate method mode is relatively simple, generally is defined by the abstract class template me

Design mode one to 20 is Gof "design mode" content summary, and use PHP instructions to implement, Gof "design mode" refers to the code is C + +. Examples are not particularly typical.At present, I am in the framework of the development project, the use of the pattern has to the appearance mode, proxy mode, adapter and other modes, these are not for the pattern,

base classDo not let classes derive from specific classesA variable cannot hold a reference to a specific class6: Abstract Factory Method mode provides an interface for creating a family of related or dependent objects without having to specify a specific class.The factory method pattern uses inheritance: Delegate the creation of objects to subclasses, subclasses implement factory methods to create objects, and abstract factory method patterns use a

Talking about 23 design patterns from chasing mm-it's classic. Go to your blog and add them first. As a programmer, the design pattern is becoming increasingly popular. the attention of the net community. This change is very gratifying. the Java Community is ahead of us, but this situation may change one day. Talking about 23 Java

High-quality code design patterns for large. NET ERP Systems1 Cached cacheIn the system, a large number of cache design patterns are used to cache the data unchanged after the system is logged in, and not read directly from the database. Consuming some memory is much more cost-effective than reading data again from SQL

For Java programmers, mastering object-oriented design theory and some design patterns is an essential skill. To start programming without learning a theory is similar to learning a language without studying the alphabet. There's a lot of object-oriented theory, design patterns
