前言
在swing界面开发的时候，为了给我们的界面改变的更加美观，所以要给界面添加背景图片，这里我总结了一个demo进行操作这些元素，包括背景图片的添加，JtextPane添加背景图片不覆盖文字，还有Swing界面启动的时候替换左上角的图标。
直接上demo代码

总结
这个演示代码的内容精简，拿来即用型，这里我也分享了我的该demo的源码，里面包含了图片与具体项目结构。
链接：https://pan.baidu.com/s/1JhlH6OLByeC6m2uugtOOzA
提取码：f91a
这里首先要说明一个问题：有的时候你替换背景图片的时候重启项目的时候，会在添加图片的那一行报空指针异常，这个问题就在于，你的图片新添加的，没有加载到类目录上面，你需要将的你的项目build一下，或者最简单的方法就是将你的IDEA进行restart操作一下，他就将图片加载到类路径下。
