二、创意角度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）
三、java swing版 效果展示从代码，项目标签，linux等多方面 画一颗圣诞树，让圣诞变得花里胡哨！
（播放有音乐）
（基于jdk11）

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：

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

我们首先找到张圣诞树图片
图片需要转换成pnm格式 可以利用在线转换网站或者工具进行转换 ， 转换后的文件名字 重命名 例如叫 merry.pnm
将图片上传至linux,
centos使用ascillview merry.pnm命令
Ubuntu使用aview merry.pnm命令
注： 使用命令前需要先安装aa-lib,aview,ImageMagick等环境 ，
具体教程可以在我博客主页搜索 : 如何实现将图片用代码打印出来
