本文探讨了在Tapestry框架中如何通过AppModule进行默认配置的设置，并尝试将这些配置值注入到组件中以便使用。同时，提出了当前实现方式中存在的问题及寻求更佳实践方案。

in AppModule.java

public static void contributeApplicationDefaults(
           MappedConfiguration<String, String> configuration)
   {
       configuration.add("tutor.file-system-root", "/Users/pbeshai/tmproot/");
       configuration.add("tapestry.supported-locales", "en");
       configuration.add("tapestry.start-page-name", "Login");
   }

And hopefully be able to inject that value into components where
necessary. Is there a more advised way of doing this?

Unfortunately, I am unable to retrieve this value in my component
(from simple lack of know-how).

I thought it might be similar to
@Inject
@Value("${tutor.file-system-root}")
private String _fileSystemRoot;

public String getFileSystemRoot() { return _fileSystemRoot; }
