springboot3整合javafx解决bean注入问题

springboot整合javafx时候，很多问题就在于controller没有被spring容器管理，无法注入bean，在这里提供一套自己的解决思路

 

执行逻辑

这里仅仅提供一个演示，我点击按钮之后，从service层返回一个文本并显示

项目结构

创建一个springboot项目

 

关键代码

springboot启动类中

FXApplication启动类中

全部代码

仅作示例，自行修改

VideoClassificationApplication

application.yaml

这里也就是你自己平时用的连接数据库的配置，还想看我的？

hello.fxml 一个简单的页面

TestServiceImpl

}

TestService

public interface TestService {String test();
