数据导入组件导入报错

报如下错
No import configurations found for entity
简单跟了一下代码,发现需要在表ImportConfiguration中做配制,不知道怎么配制方法
SELECT e FROM ddcdi$ImportConfiguration e where e.entityClass = :propertyValue0

能说一下操作步骤吗?

1.直接把dataimport组件引入项目
2.加入如下代码,跑程序,报上面的错

public class RkdBrowse extends StandardLookup<Rkd> implements WithImportWizard { //

    @Inject
    protected CollectionContainer<Rkd> rkdsDc;

    @Inject
    protected GroupTable<Rkd> rkdsTable;

    @Override
    public Map<String, Object> getDefaultValues() {
        return null;
    }

    @Inject
    protected ButtonsPanel buttonsPanel;

    @Override
    public ListComponent getListComponent() {
        return rkdsTable;
    }

    @Override
    public CollectionContainer getCollectionContainer() {
        return rkdsDc;
    }

    @Override
    public ButtonsPanel getButtonsPanel() {
        return buttonsPanel;
    }

参考这部分文档来给实体配置导入参数:
