一、前言

一年一度的圣诞节来了让我们一起动动小手给平凡而普通的生活添加一笔色彩吧
看看谁敢说程序员不懂浪漫？程序员一天能new 1024个对象（GC 此时有话要说）

二、创意角度

从代码，项目标签，linux等多方面画一颗圣诞树，让圣诞变得花里胡哨！

三、java swing版效果展示

（播放有音乐）
在这里插入图片描述

四、java swing版实现步骤&代码

（基于jdk11）

main方法

package view;public class Main {// 程序入口，运行此处public static void main(String[] args) {try {new MyFrame();} catch (Exception e) {e.printStackTrace();}}
}

JFrame方法

package view;import javax.swing.*;public class MyFrame extends JFrame {MyPanel p;MyFrame() throws Exception {p = new MyPanel();add(p);setBounds(400, 200, 800, 800);setVisible(true);validate();setDefaultCloseOperation(MyFrame.EXIT_ON_CLOSE);}
}

Jpanel方法（核心实现）

package view;import javax.sound.sampled.AudioInputStream;
import javax.sound.sampled.AudioSystem;
import javax.sound.sampled.Clip;
import javax.swing.*;
import java.awt.*;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.io.File;
import java.net.MalformedURLException;
import java.net.URI;
import java.net.URL;public class MyPanel extends JPanel implements ActionListener {// 图片、音乐路径 音乐推荐wav格式 static final String MUSIC = "src/resouce/music.wav";static final String STAR_SHINE = "src/resouce/STAR_SHINE.png";static final String STAR_NOT_SHINE = "src/resouce/STAR_NOT_SHINE.png";static final String ON = "src/resouce/ON.png";static final String OFF = "src/resouce/OFF.png";int x, y;JButton onOff;Timer time;boolean flag;boolean color;File file = new File(MUSIC);URL url = null;URI uri = null;//   since jdk9 : Clip (jdk9 before : AudioClip)Clip clip = null;AudioInputStream ais = null;MyPanel() throws Exception {setLayout(null);ImageIcon icon = new ImageIcon(OFF);icon.setImage(icon.getImage().getScaledInstance(50, 50, 0));onOff = new JButton();onOff.addActionListener(this);onOff.setIcon(icon);onOff.setBorder(null);onOff.setContentAreaFilled(false);onOff.setBounds(0, 0, 50, 50);add(onOff);flag = true;color = true;time = new Timer(300, this);time.stop();try {uri = file.toURI();url = uri.toURL();} catch (MalformedURLException e1) {System.out.println(e1);}clip = AudioSystem.getClip();ais = AudioSystem.getAudioInputStream(file);clip.open(ais);}public void paintComponent(Graphics g) {x = 380;y = 100;if (color) {ImageIcon image1 = new ImageIcon(STAR_NOT_SHINE);g.drawImage(image1.getImage(), x - 3, y - 25, 28, 26, null);} else {ImageIcon image1 = new ImageIcon(STAR_SHINE);g.drawImage(image1.getImage(), x - 3, y - 25, 25, 25, null);}Color red = new Color(255, 0, 0);Color yellow = new Color(255, 241, 0);drawTree(1, 4, g);if (color) {drawDecoration(x + 22, y - 44, 6, yellow, g);drawDecoration(x, y - 22, 8, red, g);} else {drawDecoration(x + 22, y - 44, 6, red, g);drawDecoration(x, y - 22, 8, yellow, g);}x = 380 - 2 * 22;drawTree(3, 6, g);if (color) {drawDecoration(x + 22, y - 44, 10, yellow, g);drawDecoration(x, y - 22, 12, red, g);} else {drawDecoration(x + 22, y - 44, 10, red, g);drawDecoration(x, y - 22, 12, yellow, g);}x = 380 - 4 * 22;drawTree(5, 8, g);if (color) {drawDecoration(x + 22, y - 44, 14, yellow, g);drawDecoration(x, y - 22, 16, red, g);} else {drawDecoration(x + 22, y - 44, 14, red, g);drawDecoration(x, y - 22, 16, yellow, g);}x = 380 - 1 * 22;drwaRoot(g);}void drawTree(int from, int to, Graphics g) {Color c = new Color(9, 124, 37);g.setColor(c);for (int i = from; i <= to; i++) {for (int j = 0; j < (i * 2 - 1); j++) {g.fillRect(x, y, 20, 20);x += 22;}x = 380 - i * 22;y += 22;}}void drawDecoration(int tx, int ty, int num, Color c, Graphics g) {g.setColor(c);g.fillRoundRect(tx, ty, 18, 18, 18, 18);g.fillRoundRect(tx + num * 22, ty, 18, 18, 18, 18);}void drwaRoot(Graphics g) {Color c = new Color(131, 78, 0);g.setColor(c);for (int i = 0; i < 4; i++) {for (int j = 0; j < 3; j++) {g.fillRect(x, y, 20, 20);x += 22;}x = 380 - 1 * 22;y += 22;}}public void actionPerformed(ActionEvent e) {if (e.getSource() == onOff) {if (flag) {ImageIcon icon = new ImageIcon(ON);icon.setImage(icon.getImage().getScaledInstance(50, 50, 0));onOff.setIcon(icon);try {clip.start();} catch (Exception exc) {exc.printStackTrace();}flag = false;clip.setLoopPoints(0, -1);time.restart();} else {ImageIcon icon = new ImageIcon(OFF);icon.setImage(icon.getImage().getScaledInstance(50, 50, 0));onOff.setIcon(icon);flag = true;time.stop();clip.stop();}} else if (e.getSource() == time) {repaint();color = !color;}}
}

目录结构、资源路径：

音乐推荐wav格式，且开关图片、星星图片、音乐可以自由替换，替换后注意文件名保持一致或在代码里面将相应文件名更改。
静态资源、代码地址：

五、springboot项目banner版效果展示

想想你把这个效果提交到git dev分支之后，同事启动项目时会不会觉得小惊喜呢
在这里插入图片描述

六、springboot项目banner版实现步骤

在resources目录下新建banner.txt文件文件名必须是这个，这是springboot的机制，根据名字读取。（和我们的application.yml处于同级目录）
将符号文字复制进去，启动项目即可。同样的符号文字也是可以随意替换的我们可以在网上找更好看的符号或者动手能力强的同学可以自己设计
