Tapestry用来对服务进行配置的方式

对服务进行配置需要用到contribute，然后+serviceId。

看一下代码：

public static void arbitraryMethodName(MappedConfiguration<String,FileServicer> configuration)
{
    configuration.add("doc", new WordFileServicer());
    configuration.add("ppt", new PowerPointFileServicer());
}

其中可能最令人不解的就是MappedConfiguration了。

There are three different styles of configurations (with matching contributions):

有三种不同形式的configuration

• Unordered Collection – Contributions are simply added in and order is not important.
  • 　　不排序的集合， 配置简单的追加进去，顺序一点也不重要。
    • 　　Configuration<Runnable> configuration
• Ordered List – Contributions are provided as an ordered list. Contributions must establish the order by giving each contributed object a unique id, by establishing forward and backward dependencies between the values.
  • 　　排序的集合
    • 　　OrderedConfiguration<Runnable> configuration
• Map – Contributions provide unique keys and corresponding values.
• 　　映射表
• 　　MappedConfiguration<String,FileServicer> configuration
