我有一个资源类

public interface  Resources extends ClientBundle {
      public static final Resources INSTANCE =  GWT.create(Resources.class);

      @Source("logo.png")
      ImageResource logo();


}

我在 GWT XML 编辑器中没有收到任何错误，但是，GWT 设计器不会加载。一个当我运行它时，我也会得到一个异常。

onModuleLoad() threw an exception

很难说是不是你的问题，但你的代码应该是：

<g:Image resource='{res.logo}'/>

（即resource，不是url）

确保你的 gwt.xml 文件中有这个继承标签，使用 ClientBundle 时需要它：

<inherits name="com.google.gwt.resources.Resources" />
