使用JSF Facelets的国际化(i18n):Java类中的消息 [英] Internationalization (i18n) using JSF Facelets: Messages in Java-classes

问题描述

我已经在我的项目中成功实施了i18n.现在我被卡在豆子里了...

I have successfully implemented i18n in my project. Now I'm stuck in my Bean...

private String pageTitle;
public List<Product> getProductsByCategory(String category) {
  if(validate(category)) {
    pageTitle = category;
    return service.getProductsByCategory(String category);
  } else {
    pageTitle = "Random products";
    return service.getRandomProducts();
  }
}

如您所见，我想让我的pageTitle依赖于所提供方法的结果.一切都很好，但是考虑到国际化，这还不是很好.我尝试使用Properties.load(new FileInputStream)方法，但是考虑到文件名为base.properties，base_en_US.properties等，此方法不起作用.

As you can see, I would like to let my pageTitle depend on the result of the provided method. All fine, but this is not fine considering internationalization. I have tried using a Properties.load(new FileInputStream) approach, but this does not work considering the files are name base.properties, base_en_US.properties and so on.

有人知道这种情况下的最佳实践吗?预先感谢！

Does anyone know the best practice in this kind of situation? Thanks in advance!

推荐答案

您需要使用与JSF相同的方式来装载资源束:使用

You need to use the same way as JSF is under the covers using to load resource bundles: using the ResourceBundle API. Here's an example assuming that the base name is com.example.i18n.base (exactly the value as you'd use in <f:loadBundle> in view or <resource-bundle> in faces-config.xml)

ResourceBundle bundle = ResourceBundle.getBundle("com.example.i18n.base",
    FacesContext.getCurrentInstance().getViewRoot().getLocale());
String pageTitle = bundle.getString("page.title");
// ...
