如何添加上传excel功能，并绑定数据库entity，老版的cuba 项目
CUBA 有一个数据导入组件，支持直接上传 excel 并绑定数据库实体：

好的，在试图安装数据导入插件组件时，电脑是联网的，marketplace刷不出来如何处理？
目前使用的是cuba studio
嗯。好像确实有问题，已经跟 studio 团队反馈了。可以先尝试手动安装：
https://doc.cuba-platform.cn/manual-7.2-chs/app_components_usage.html#app_components_usage_manual_edit
你好，导入时有个service注册问题需要怎么处理，帮忙看一下

你看看程序启动的日志，是否有报什么错？
启动日志没有报错的，数据库关联实体有什么注解要加吗
实体类没有什么注解需要加的。但是你贴这个图的实体带了 @Component 是有什么特殊用法吗？一般实体不需要作为 bean 的
没有特殊用法，就是根据上面的报错才临时加的，加不加都是报同样的错误
方便上传一下整个日志文件吗？
好的，这是我在本地调式的日志
