如何正确地将 Vaadin 框架添加到我的 Spring Boot 项目中？

Question

我正在尝试将此官方 Vaadin 视频教程（实施后端推送通知）中的内容集成到我的 Spring 引导项目中。我发现一些问题试图了解如何将 Vaadin 框架正确集成到我现有的 Spring 引导项目 pom.xml 文件中，以便拥有工作所需的所有依赖项.

基本上这就是视频教程 link：https://www.youtube.com/watch?v=M5sbGvW3S4I

这是本教程示例代码的相关 GitHub link：https://github.com/marcushellberg/fusion-push-notifications

这是我已经存在的 Spring 引导项目的 pom.xml，我需要在其中插入 Vaadin 框架和相关的示例项目依赖项（需要实施所需的行为）

但它似乎不起作用，我在 pom.xml

的这个新版本上遇到了很多错误

我错过了什么？我怎样才能尝试将 Vaading 框架正确添加到我原来的 Spring 启动项目？

Answer 1

我认为唯一缺少的是 vaadin.version...

    <properties>
        <java.version>11</java.version>
        <vaadin.version>19.0.8</vaadin.version> <!-- missing -->
    </properties>

但是你应该避免混用 spring 版本，这有时会导致一些问题。示例：spring-boot-starter-parent:2.4.5 和 spring-boot-starter-aop:2.6.3
