Java GWT:重新绑定结果必须是类

java gwt

Java GWT:重新绑定结果必须是类,java,gwt,Java,Gwt,我已经编写了一个生成器类，它为我们的DTO创建了一个简单的适配器。基本上，生成的代码所做的就是查看DTO的所有方法以找到getter，并创建一个getProperty（String）方法以根据属性名称检索属性在编译器尝试编译GWT.create（）语句之前，一切似乎都正常，然后我得到了“必须是类”错误感谢您的帮助下面有很多东西来解释这个问题谢谢埃德这是my.gwt.xml的一部分： <generate-with class="com.kn.tls.acsuk.mobile.ge

我已经编写了一个生成器类，它为我们的DTO创建了一个简单的适配器。基本上，生成的代码所做的就是查看DTO的所有方法以找到getter，并创建一个getProperty（String）方法以根据属性名称检索属性

在编译器尝试编译GWT.create（）语句之前，一切似乎都正常，然后我得到了“必须是类”错误

感谢您的帮助

下面有很多东西来解释这个问题

谢谢

这是my.gwt.xml的一部分：

创建RebindResult类时，应该使用生成类的限定源名称，而不是接口的限定源名称

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

看起来您使用的是接口的名称。

这不正确。GWT.create（）需要传入您在.GWT.xml文件中配置的任何内容（在我的示例中，它应该查找ModelAdapterFactory）。generate（）方法需要返回字符串，而不是重新绑定的结果。这取决于您如何实现生成器。使用“generateIncrementally”将返回重新绑定结果。在使用SDM的上下文中使用generate方法不是最好的主意。
