java - RapidClipseX、MicroStreamDB : How to assign MicroStream Table to RapidClipseX Grid?

Question

我尝试使用 RapidClipseX 和 MicroStreamDB。 我生成了一个存储，在不同的表对象中导入了不同的数据。 现在我想读取数据并在 RapidClipseX Grid 组件中将其可视化。

通过使用 MicroStreamDB，我没有像 Hibernate 中那样的 DAO 对象。 我仍然不知道该怎么做。 RapidClipseX 文档中也没有可用的示例，Microstream 文档中也没有任何可用示例。

我尝试使用以下分配，它仍然填充网格。 但它用大约 6000 行填充网格，这仍然是表中的行数。但每一行的内容相同，仍然是 db-table 中最后保存的行。 (我仍然通过文本编辑器检查 MicrostreamDB 是否存储了正确的数据。--> 是的，它已经存储了)

private void grid_onAttach(final AttachEvent event)
{
    final dataRoot               root    = dbHandler.getRoot();
    this.grid.setDataProvider(DataProvider.ofCollection(root.getAllUmsClassifications()));
}

这是我使用的表的类:

import static javax.persistence.GenerationType.IDENTITY;
import java.util.Date;
import javax.persistence.Column;
import javax.persistence.GeneratedValue;

我目前还没有使用过它。不幸的是，没有更新的文档。我无法将我们的应用程序迁移到 X，因为 X 没有图表。
