Question

我编写了一个生成器类，为我们的DTO创建了一个简单的适配器。基本上，所有生成的代码都是查看DTO的所有方法来查找getter，并创建一个getProperty（String）方法来根据其属性名称检索属性。

在编译器尝试编译GWT.create（）语句之前，一切似乎都没问题，然后我得到＆＃34;必须是一个类＆＃34;错误。

感激不尽的任何帮助。

下面的大量内容解释问题。

谢谢，

这是我的.gwt.xml部分：

<generate-with class="com.kn.tls.acsuk.mobile.generator.ModelAdaptorFactoryGenerator" >
    <when-type-is class="com.kn.tls.acsuk.mobile.generator.ModelAdaptorFactory"/>
</generate-with>

这是控制台输出的一部分，显示正在运行的生成器：

这是导致构建失败的日志的后一部分：

在创建RebindResult类时，您应该使用生成的类的限定源名称而不是接口。

我期待这样的事情：

return new RebindResult(RebindMode.USE_ALL_NEW_WITH_NO_CACHING,
                        packageName + "." + generatedClassName);

其中generatedClassName是生成的类的名称。

看起来你正在使用界面的名称。

GWT：Rebind结果必须是一个类
