摘要：原则1：DRY（Don't repeat yourself）即不要写重复的代码，而是用“abstraction”类来抽象公有的东西。如果你需要多次用到一个硬编码值，那么可以设为公共常量；如果你要在两个以上的地方使用一个代码块，那么可以将它设为一个独立的方法。SOLID设计原则的优点是易于维护，但要注意，不要滥用，duplicate 不是针对代码，而是针对功能。这意味着，即使用公共代码来验证OrderID和SSN，二者也不会是相同的。使用公共代码来实现两个不同的功能，其实就是近似地把这两个功能永远捆绑到了一起，如果OrderID改变了其格式，SSN验证代码也会中断。因此要慎用这种组合，不
