感谢这篇文章,https://stackoverflow.com/a/28047512/1227941我现在正在使用CDI使msg在我的@Named bean中可用,如下所示:
@RequestScoped
public class BundleProducer {
@Produces
public PropertyResourceBundle getBundle() {
FacesContext context = FacesContext.getCurrentInstance();
return context.getApplication().evaluateExpressionGet(context, "#{msg}", PropertyResourceBundle.class);
}
}
使用注射方式:
@Inject
private PropertyResourceBundle bundle;
问题:如果我有更多属性文件:ui.properties
,admin.properties
...该怎么办?
答案 0 :(得分:2)
我只是使用分类器注释来选择要注入的包。从我的一个小项目中偷来的:
注释:
@Qualifier
@Target({ ElementType.TYPE, ElementType.METHOD, ElementType.FIELD, ElementType.PARAMETER })
@Retention(RetentionPolicy.RUNTIME)
public @interface Bundle {
@Nonbinding
public String value() default "";
}
生产者方法(根据您的情况进行适当调整):
@Produces @Bundle ResourceBundle loadBundle(InjectionPoint ip) {
String bundleName = ip.getAnnotated().getAnnotation(Bundle.class).value();
ResourceBundle res = ResourceBundle.getBundle(bundleName);
return res;
}
还有注射:
@Inject @Bundle("ui")
private ResourceBundle uiResources;
