添加ViewComponentParam属性，它可以告知MonoRail把参数作为属性绑定到你的视图组件上——减少了重复的代码规则。
Added ViewComponentParam attribute which tells MonoRail to bind the arguments as properties on your view component - reducing repetitive code rules.
正如我在命令式版本中所做的一样，我将重复的代码提取到其factors类中，并且为便于阅读，将factors方法的名称改为of，如清单8所示。
Just as I did with the imperative versions, I extract the duplicated code into its own factors class, changing the name of the factors method to of for readability, as shown in Listing 8.
一旦运行了cpd，您的eclipse根目录下就会创建出一个report文件夹，其中包含一个叫做cpd. txt的文件，文件中列示了所有重复的代码。
Once you've run CPD, a report folder is created in your Eclipse root directory containing a file called cpd.txt, which lists all duplicate code. An example of the cpd.txt file is shown in Figure 9.
还有另一个重要的原则，在第一个案例中我们不介意有一些重复的代码，如果能够明确如何消除重复代码，我们愿意这么做，但现在还没有，我们仍然希望能找到清晰的解决方案。
Another important principle is that in the first case we don't mind having some duplicate code. If it's clear how to eliminate duplication, we do, but we are willing to wait for clarity.
