GWT 2 CSS资源如何

我有一个GWT1.7应用程序，我想将其升级到GWT2里程碑2。该应用程序使用2个大的外部CSS文件。在GWT1.7中，我有一个公用文件夹，并将CSS文件放在该文件夹中，我的应用程序编译后运行良好。现在，对于GWT 2，我创建了一个ResourceBundle类，并将所有图像精灵和CSS放在下面：

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类是扩展CssResource的空类：

public interface Css extends CssResource{

}

然后在onModuleLoad（）中，我使用：

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.

解决了。 正如Thomas@Google组-->不得将@external置于样式的“上方”

此链接中的示例，css将如下所示：

@external .legacySelectorA, .legacySelectorB;
.obfuscated .legacySelectorA { .... }
.obfuscated .legacySelectorB { .... }

/* @external also accepts tail-globs */
@external .myProject-*;
.myProject-text {}
.myProject-foo {}

尝试使用

@NotStrict

。例如：

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

@NotStrict

是“不建议用于新代码”：

@external .legacySelectorA, .legacySelectorB;
.obfuscated .legacySelectorA { .... }
.obfuscated .legacySelectorB { .... }

/* @external also accepts tail-globs */
@external .myProject-*;
.myProject-text {}
.myProject-foo {}

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