The framework supports internationalization (i18n) in the following places:
Resource bundles are searched in the following order:
For more, see the LocalizedTextUtil class.
There are several ways to access the message resources, including
text tag, and the
getTextfrom a Tag
To display i18n text, use a call to
getText in the property tag, or any other tag, such as the UI tags. (The
getText technique is especially useful for labels of UI tags.)
The text tag retrieves a message from the default resource bundle.
The i18n tag pushes an arbitrary resource bundle on to the value stack. Other tags within the scope of the i18n tag can display messages from that resource bundle.
The key attribute of most UI tags can be used to retrieve a message from a resource bundle:
Essentially, the i18n Interceptor pushes a locale into the ActionContext map upon every request. The framework components that support localization all utilize the ActionContext locale. See I18n Interceptor for details.
A global resource bundle could be specified programatically, as well as the locale.
See Formatting Dates and Numbers for more details and examples.
Struts 1 users should be familiar with the application.properties resource bundle, where you can put all the messages in the application that are going to be translated. Struts 2, though, splits the resource bundles per action or model class, and you may end up with duplicated messages in those resource bundles. A quick fix for that is to create a file called ActionSupport.properties in com/opensymphony/xwork2 and put it on your classpath. This will only work well if all your actions subclass XWork2's ActionSupport.
