我正在尝试在 GWT 中使用 ClientBundle 来加载消息。

这是我的代码：gwt.xml

<?xml version="1.0" encoding="UTF-8"?>
<module rename-to='StockWatcher'>
    <!-- Inherit the core Web Toolkit stuff.                        -->
    <inherits name='com.google.gwt.user.User'/>

    <!-- We need the JUnit module in the main module,               -->
    <!-- otherwise eclipse complains (Google plugin bug?)           -->
    <inherits name='com.google.gwt.junit.JUnit'/>

    <!-- Inherit the default GWT style sheet.  You can change       -->
    <!-- the theme of your GWT application by uncommenting          -->
    <!-- any one of the following lines.                            -->
    <inherits name='com.google.gwt.user.theme.standard.Standard'/>
    <!-- <inherits name='com.google.gwt.user.theme.chrome.Chrome'/> -->
    <!-- <inherits name='com.google.gwt.user.theme.dark.Dark'/>     -->

    <!-- Other module inherits                                      -->

    <!-- Specify the app entry point class.                         -->
    <entry-point class='ro.gebs.master.client.StockWatcher'/>

    <!-- Specify the paths for translatable code                    -->
    <source path='client'/>
    <source path='shared'/>
    <source path='resources'/>

</module>

扩展 ClientBundle 的接口：

public interface Resources extends ClientBundle {
    Resources IMPL = (Resources) GWT.create(Resources.class);

    @Source("ro/gebs/master/resources/blogger.png")
    ImageResource blogger();
    @Source("ro/gebs/master/resources/delicious.png")
    ImageResource delicious();
    @Source("ro/gebs/master/resources/facebook.png")
    ImageResource facebook();
}

在这里，我尝试在我的 EntryPoint 类中使用图像：

ImageResource[] icons = new ImageResource[]{
                Resources.IMPL.blogger(),
                Resources.IMPL.delicious(),
                Resources.IMPL.facebook()
        };

我得到的错误是：

这些图像被放置在一个名为“resources”的包中，但我从错误中了解到的行GWT.create()似乎是问题所在。

尝试如下所示的相对位置

@Source("../resources/blogger.png")
ImageResource blogger();
@Source("../resources/delicious.png")
ImageResource delicious();
@Source("../resources/facebook.png")
ImageResource facebook();

项目结构

ro/gebs/master
            |
            |__resources
            |          |
            |          |__blogger.png
            |
            |__client
                     |
                     |__StockWatcher.java

确保图像以正确的名称和扩展名放置在正确的位置。

删除Resources{module}.gwt.xml 中的路径条目。它不需要。

<source path='resources'/>
