我正在嘗試將這個官方 Vaadin 視頻教程（實作后端推送通知）中所做的事情集成到我的 Spring Boot 專案中。我發現一些問題試圖了解如何將 Vaadin 框架正確集成到我現有的 Spring Boot 專案pom.xml檔案中，以便擁有作業所需的所有依賴項。
所以基本上這是視頻教程鏈接：https ://www.youtube.com/watch?v=M5sbGvW3S4I
這是本教程示例代碼的相關 GitHub 鏈接：https ://github.com/marcushellberg/fusion-push-notifications
這是我已經存在的 Spring Boot 專案的pom.xml，我需要在其中插入 Vaadin 框架和相關的示例專案依賴項（需要實作所需的行為）

但這似乎行不通，我的pom.xml的這個新版本出現了很多錯誤
我錯過了什么？如何嘗試將 Vaading 框架正確添加到我原來的 Spring Boot 專案中？
uj5u.com熱心網友回復：
我認為唯一真正缺少的是vaadin.version...
<properties>
<java.version>11</java.version>
<vaadin.version>19.0.8</vaadin.version> <!-- missing -->
</properties>
但是您應該避免混合使用彈簧版本，這有時會導致一些問題。示例：spring-boot-starter-parent:2.4.5和spring-boot-starter-aop:2.6.3
