延迟绑定失败错误

Question

我无法解决此异常。我正在尝试在 GWT 展示中的 gwt 中实现单元格表。以下是我的例外。

我在下面的部分到达这里..

   interface DatabaseConstants extends Constants {
        String[] contactDatabaseCategories();
    }
    DatabaseConstants constants = GWT.create(DatabaseConstants.class);

Answer 1

这可能是一些事情，首先检查您有一个 DatabaseConstants.properties 文件来存储值，然后确保键 contactDatabaseCategories 存在并且具有逗号分隔的值列表。也可能必须将常量创建为独立类

更新

将接口移至它自己的 .java 文件 在 .java 文件的同一级别创建一个名为 DatabaseConstants.properties 的文本文件 里面可以放

contactDatabaseCategories=Category1,Category2

这应该会停止该错误并为您提供一个值以获取更多信息，请查看constants
