原文:使用java将bing的每日壁纸设置为ubuntu壁纸
源代码下载地址:http://www.zuidaima.com/share/1550463714806784.htm
早上起来浏览bing的时候突然有了想要把bing的每日壁纸设为ubuntu的桌面壁纸的想法,中午从机房回来后就开始写代码。先是解析xml,获取壁纸的下载地址,然后是下载壁纸,最后调用ubuntu的命令设置壁纸。
在我的ubuntu13.04上运行成功。建议将这个java文件编译然后打包成jar,修改/etc/rc.local 在exit 0 前添加该jar文件的运行命令,比如我的写成 java -jar /home/kongkongyzt/wallpaper.jar
这样每天开机就会自动换壁纸了。
代码量很小,不规范的地方很多,希望大家指出~~
