引言

springboot开发项目现在是java开发的主流，springboot也集成了很多功能，如aop和表单检测，比常规的单体Javafx项目或者maven项目要好用多，springboot开发Javafx项目主要有两种方式，一种是直接继承实现CommandLineRunner，还有一种是实现AbstractJavaFxApplicationSupport，本文将详细说明。

1，CommandLineRunner

在使用SpringBoot构建项目时，我们通常有一些预先数据的加载。那么SpringBoot提供了一个简单的方式来实现–CommandLineRunner。
在主调用接口实现这个接口，在接口方法中启动javafx主类窗口，这样好处是最小程度侵入，适合将原javafx项目直接移植到springboot，在此基础上使用springboot的相关插件，十分方便。

ConsoleApplication.java

import com.yz.sample.MainApp;
import javafx.application.Application;
import org.springframework.boot.CommandLineRunner;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class ConsoleApplication implements CommandLineRunner {

     public static void main(String[] args) {
        SpringApplication.run(ConsoleApplication.class, args);
    }

    @Override
    public void run(String... args) throws Exception {
        Application.launch(MainApp.class, args);
    }
}

MainApp.java

import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.layout.AnchorPane;
import javafx.stage.Stage;

public class MainApp extends Application {

    @Override
    public void start(Stage primaryStage) throws Exception {
        AnchorPane anchorPane=new AnchorPane();

        Scene scene=new Scene(anchorPane);

        primaryStage.setScene(scene);
        primaryStage.show();
    }
}

启动springboot，并且打开fx窗口

2，继承实现 AbstractJavaFxApplicationSupport

springboot-javafx-support将Spring Boot与JavaFx 8链接在一起。让您所有的视图和控制器类都成为Spring Bean，并利用Spring Universe中的所有功能。

jar包集成

<dependencies>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter</artifactId>
        </dependency>
 
        <dependency>
            <groupId>de.roskenet</groupId>
            <artifactId>springboot-javafx-support</artifactId>
            <version>2.1.6</version>
        </dependency>
 
 
        <dependency>
            <groupId>de.roskenet</groupId>
            <artifactId>springboot-javafx-test</artifactId>
            <version>1.3.0</version>
            <scope>test</scope>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-test</artifactId>
            <scope>test</scope>
        </dependency>
    </dependencies>

spring-boot-starter和spring-boot-starter-test是springboot需要的，springboot-javafx-support和springboot-javafx-test是javafx整合springboot所需要的，其中test是测试需要的包。

AbstractJavaFxApplicationSupport是springboot-javafx-support的核心类，继承了javaFX的Application类，主类是需要继承AbstractJavaFxApplicationSupport这个类型，添加main方法和SpringBootApplication注解。使用launch方法代替SpringApplication.run

关于springboot-javafx-support 资料很多，这里就不再赘述直接放链接了，
