（三）创建基于maven的javaFX+springboot项目创建

创建基于maven的javafx+springboot项目有两种方式，第一种为通过非编码的方式来设计ui集成springboot；第二种为分离用户界面（ui）和后端逻辑集成springboot，其中用户界面为fxml文件。

maven依赖

        <dependency>
            <groupid>org.springframework.boot</groupid>
            <artifactid>spring-boot-starter-actuator</artifactid>
            <version>${spring.boot.version}</version>
        </dependency>
        <dependency>
            <groupid>org.springframework.boot</groupid>
            <artifactid>spring-boot-starter</artifactid>
            <version>${spring.boot.version}</version>
        </dependency>
        <dependency>
            <groupid>de.roskenet</groupid>
            <artifactid>springboot-javafx-support</artifactid>
            <version>${springboot-javafx-support.version}</version>
        </dependency>    

创建startmain类，并继承application

import javafx.application.application;
import javafx.geometry.insets;
import javafx.scene.group;
import javafx.scene.scene;
import javafx.scene.control.button;
import javafx.scene.control.label;
import javafx.scene.layout.gridpane;
import javafx.scene.layout.hbox;
import javafx.stage.stage;
import org.springframework.boot.commandlinerunner;
import org.springframework.boot.springapplication;

import java.util.objects;
import java.util.function.consumer;

/**
 *  maven构建javafx项目启动类
 */
public class startmain extends application implements commandlinerunner, consumer<stage> {

    /**
     * 窗口启动接口，原理：
     * 1. run(string... args)中给springstartmain赋值
     * 2. start(stage primarystage)中调用了springstartmain来操作primarystage
     * 3. 而springstartmain实际上是spring管理的startmain一个对象，因此accept方法中可以操作spring管理的任何对象
     */
    private static consumer<stage> springstartmain;
    private final button btnstart = new button("开 始");

    @override
    public void accept(stage stage) {

        final gridpane gridpane = new gridpane();
        gridpane.setprefwidth(700);
        gridpane.setpadding(new insets(10, 10, 10, 10));
        gridpane.setvgap(10);
        gridpane.sethgap(10);
        btnstart.setstyle("-fx-padding: 10;-fx-end-margin:20;");
        hbox hbox1 = new hbox();
        hbox1.getchildren().addall(btnstart);
        hbox1.setspacing(20);
        gridpane.addrow(2, new label(), hbox1);
        //页面
        group root = new group();
        scene scene = new scene(root, 720, 500);
        scene.setroot(gridpane);

        //设置标题
        stage.settitle("hello world");
        //stage的标题将会是hello
        stage.setscene(scene);
        stage.show();
    }

    @override
    public void start(stage primarystage) throws exception {
        springstartmain.accept(primarystage);
    }

    @override
    public void run(string... args) throws exception {
        springstartmain = objects.requirenonnull(this);
    }

    public static void main(string[] args) {
        //启动spring-boot
        springapplication.run(startmain.class, args);
        //启动窗口
        application.launch(args);
    }

}

项目结构如下：
