本文主要是介绍JavaFX 结合 spring boot，对大家解决编程问题具有一定的参考价值，需要的程序猿们随着小编来一起学习吧！

javafx 基于Java的桌面程序的开发技术

阅读此文档要求了解JavaFX的的基本结构

此文档含项目创建,代码介绍,构建安装包

创建项目

• 创建maven项目,调整pom.xml依赖

<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>2.1.9.RELEASE</version>
</parent>
<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>
</dependencies>

创建视图类与视图文件(fxml)

视图类

package com.example.view;

import de.felixroske.jfxsupport.AbstractFxmlView;
import de.felixroske.jfxsupport.FXMLView;

@FXMLView(value = "/view/demo.fxml")
public class DemoView extends AbstractFxmlView {
}

fxml

<?xml version="1.0" encoding="UTF-8"?>
<?import javafx.scene.control.Button?>
<?import javafx.scene.layout.FlowPane?>
<FlowPane
    xmlns:fx="http://javafx.com/fxml/1"
    xmlns="http://javafx.com/javafx/8"
    fx:controller="com.example.controller.DemoController">
    <children>
        <Button fx:id="button" onAction="#click"  text="测试按钮" />
    </children>
</FlowPane>

备注:javafx 启动过程较慢,此功能默认会加载一个动画

动画类

package com.example.splash;

import de.felixroske.jfxsupport.SplashScreen;

public class DemoSplash extends SplashScreen {
    @Override
    public boolean visible() {
        return super.visible();
    }

    @Override
    public String getImagePath() {
        return super.getImagePath();
    }
}

启动类

package com.example;

import com.example.splash.DemoSplash;
import com.example.view.DemoView;
import de.felixroske.jfxsupport.AbstractJavaFxApplicationSupport;
import javafx.stage.Stage;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.ConfigurableApplicationContext;

@SpringBootApplication
public class DemoApplication extends AbstractJavaFxApplicationSupport {
    public static void main(String[] args) {
        launch(DemoApplication.class, DemoView.class,new DemoSplash(), args);
    }
    @Override
    public void beforeInitialView(Stage stage, ConfigurableApplicationContext ctx) {
        stage.setTitle("标题");
        stage.setWidth(300);
        stage.setHeight(300);
    }
}

构建pom.xml

<build>
    <finalName>用例</finalName>
    <plugins>
        <plugin>
            <groupId>org.springframework.boot</groupId>
           <artifactId>spring-boot-maven-plugin</artifactId>
        </plugin>
        <plugin>
            <groupId>com.zenjava</groupId>
            <artifactId>javafx-maven-plugin</artifactId>
            <configuration>
               <mainClass>com.podigua.translate.TranslateApplication</mainClass>
               <appName>${project.build.finalName}</appName>
                <needMenu>false</needMenu>
                <needShortcut>true</needShortcut>
                <vendor>公司</vendor>
            </configuration>
        </plugin>
    </plugins>
</build>

说明

启动类

• 启动类需要继承AbstractJavaFxApplicationSupport

/**
* 1:启动类
* 2:视图类
* 3:启动动画类(SplashScreen)
*/
public static void launch(Class<? extends Application> appClass, Class<? extends AbstractFxmlView> view, SplashScreen splashScreen, String[] args){
    
}


/**
* 此处修改窗体信息
* @param stage
* @param ctx
*/
@Override
public void beforeInitialView(Stage stage, ConfigurableApplicationContext ctx) {
   stage.setTitle("标题");
   stage.setWidth(300);
   stage.setHeight(300);
}
/**
* 窗体图标
*/
public Collection<Image> loadDefaultIcons() {
    return Arrays.asList(new Image("图片"));
}

视图类

@FXMLView(value = "/view/demo.fxml")

value=fxml的路径,以/开头

控制类

@FXMLController
public class DemoController implements Initializable{
   
} 

启动动画

/**
* 动画路径
*/
@Override
public String getImagePath() {
    return super.getImagePath();
}
/**
*是否显示动画
*/
@Override
public boolean visible() {
    return false;
}

效果

打包

• 使用mvn jfx:native 进行打包
• 如何设置程序图标
  • mac:在src/main/deploy/package/macosx/${appName}.icns
  • windows:在src/main/deploy/package/windows/${appName}.ico
• 其他配置信息可以点击属性查看说明
