GWT 2 CssResource 如何

Question

我有一个 GWT 1.7 应用程序，我想将它升级到 GWT 2 Milestone 2。该应用程序使用 2 个大的外部 CSS 文件。在 GWT 1.7 中，我有一个公用文件夹，并将 CSS 文件放在该文件夹中，我的应用程序编译并运行良好。现在对于 GWT 2，我创建了一个 ResourceBundle 类并将所有图像 Sprite 和 CSS 如下所示:

public interface ResourceBundle extends ClientBundle {

 public static final ResourceBundle INSTANCE = GWT.create(ResourceBundle.class);

 @Source("com/web/tech/public/stylesheet1.css")
 public Css stylesheet1();

 @Source("com/web/tech/public/stylesheet2.css")
 public Css stylesheet2();

 @Source("com/docobo/keswick/keswickweb/public/images/organisnew.gif")
 public ImageResource add_org();

.....
}

Css 类是一个扩展 CssResource 的空类:

public interface Css extends CssResource{

}

然后在我的 onModuleLoad() 中我使用:

StyleInjector.inject(ResourceBundle.INSTANCE.stylesheet1().getText());
StyleInjector.inject(ResourceBundle.INSTANCE.stylesheet2().getText());

编译时出现以下错误:

     Rebinding com.docobo.keswick.keswickweb.client.ClientResources.ResourceBundle
            Invoking <generate-with class='com.google.gwt.resources.rebind.context.InlineClientBundleGenerator'/>
               Creating assignment for gxt_gray()
                  Replacing CSS class names
                     [ERROR] The following unobfuscated classes were present in a strict CssResource:
                        [ERROR] x-tab-scroller-left
                        [ERROR] x-tab-strip-disabled
                        [ERROR] ......loads of other styles

Fix by adding String accessor method(s) to the CssResource interface for obfuscated classes, or using an @external declaration for unobfuscated classes.

当我在 CSS 文件中的所有样式类之上使用 @external 时，按照上述说明，我收到以下错误:

Answer 1

试试 @NotStrict .例子:

@NotStrict
@Source("com/web/tech/public/stylesheet1.css")
public Css stylesheet1();
