p>再调用createView方法,通过类的完整路径来构造View对象 Building Maintainable Software-java篇之Separate Concerns in Modules In a system that is both complex and tightly coupled, accidents are inevitable.—Charles Perrow’s Normal Accidentstheory in one sentenceGuideline:• Avoid large modules in order toachieve loose coupling between them.• Do this by assigning responsibilities to separate modules and hiding implementation details behind interfaces• This improves maintainability because changes in a loosely coupled codebase are much easier to oversee and execute than changes in a tightly coupled codebase.Remember that the concept of a module translates to a class in object-oriented languages such as Java.MotivationThe biggest advantage of keeping classes small is that it provides a direct path towardloose coupling between classes. Loose coupling means that your class-level design willbe much more flexible to facilitate future changes. By “flexibility” we mean that youcan make changes while limiting unexpected effects of those changes. Thus, loosecoupling allows developers to work on isolated parts of the codebase without creatingchange ripples that affect the rest of the codebase. A third advantage, which cannot beunderestimated, is that the codebase as a whole will be much more open to less experienced developers.Small, Loosely Coupled Modules Allow Developers to Work on Isolated Parts of the CodebaseWhen a class is tightly coupled with other classes, changes to the implementation ofthe class tend to create ripple effects through the codebase. For example, changing theinterface of a public method leads to code changes everywhere the method is called.Besides the increased development effort, this also increases the risk that class modifications lead to bugs or inconsistencies in remote parts of the codebase.Small, Loosely Coupled Modules Ease Navigation Through the CodebaseNot only does a good separation of concerns keep the codebase flexible to facilitatefuture changes, it also improves the analyzability of the codebase since classes encapsulate data and implement logic to perform a single task. Just as it is easier to namemethods that only do one thing, classes also become easier to name and understandwhen they have one responsibility. Making sure classes have only one responsibility isalso known as the single responsibility principle.Small, Loosely Coupled Modules Prevent No-Go Areas for New DevelopersClasses that violate the single responsibility principle become tightly coupled and accumulate a lot of code over time. As with the UserService example in the introductionof this chapter, these classes become intimidating to less experienced developers, andeven experienced developers are hesitant to make changes to their implementation. Acodebase that has a large number of classes that lack a good separation of concerns isvery difficult to adapt to new requirements.How to Apply the GuidelineIn general, this guideline prescribeskeeping your classes small (by addressing onlyone concern) and limiting the number of places where a class is called by code outside the class itself. Following are three development best practices that help to prevent tight coupling between classes in a codebase.Split Classes to Separate ConcernsDesigning classes that collectively implement functionality of a software system is themost essential step in modeling and designing object-oriented systems. In typicalsoftware projects we see that classes start out as logical entities that implement a single functionality but over time gain more responsibilities. To prevent classes from getting a large class smell, it is crucial that developers take action if a class has more than one responsibility by splitting up the class.Hide Specialized Implementations Behind InterfacesWe can also achieve loose coupling byhiding specific and detailed implementationsbehind a high-level interface.Replace Custom Code with Third-Party Libraries/FrameworksA third situation that typically leads to tight module coupling are classes that providegeneric or utility functionality. Classic examples are classes called StringUtils andFileUtils. Since these classes provide generic functionality, they are obviously calledfrom many places in the codebase. In many cases this is an occurrence of tight coupling that is hard to avoid. A best practice, though, is to keep the class sizes limitedand to periodically review (open source) libraries and frameworks to check if theycan replace the custom implementation. Apache Commons and Google Guava arewidespread libraries with frequently used utility functionality. In some cases, utilitycode can be replaced with new Java language features or a company-wide sharedlibrary.读书笔记:Building Maintainable Software: Ten Guidelines for Future-Proof Codeby Joost VisserCopyright © 2016 Software Improvement Group, B.V.
