夹娃展示目录结构

夹娃展示目录结构

最后是酱紫

夹娃代码

其实网上都有,拿下来改两下就能用,肯定有人会问我为嘛不用jtree,俩原因,一是最开始是想做成log的样子而不是权限树,可以剪切出来处理,还是蛮方便的,所以是使用的JTextArea,换成JTextPane则是因为想着加个图标,后面没找到合适的小图标,大图标布局太*了,二是jtree没有内部逻辑,扩展起来挺麻烦,而JTextPane自己写了内部逻辑,改成jtable更容易 代码片.

MARKDOWN是要比富文本方便点

然后说下脚本

就以windows脚本为例啦,其实很简单,打好的假包朝一个固定路径一甩,然后就可以当dll来用啦 代码片.

echo off
cls

set curdir1=%~dp0
set curdriv1=%~d0

cd %curdir1%
%curdriv1%

java -jar "D:\pqy\shortcut\runinpath\wdgl.jar" %curdir1%

完鸟

以前从来不粘完整代码的,最多就是粘点snippet,今天破例一次,因为夹娃代码是在网上下下来的,只是稍微改了下而已,尊重他人劳动成果,附上他的连接https://wenda.so.com/q/1528356215218392
