Ubuntu Server 18.04.4 LTS + Xvfb + JxBrowser 6.24.3

前段时间因为要爬取淘宝店铺商品相关信息,所以决定使用JxBrowser进行抓取,但是在Mac环境开发完成后在部署到服务器上运行时却遇到了问题。

参考官方:https://jxbrowser-support.teamdev.com/docs/guides/x-server-in-headless-linux.html,执行:sudo apt-get install xvfb安装Xvfb,然后执行:Xvfb :1 -screen 0 800x600x16启动Xvfb,然后执行:xvfb-run java -jar yourApplication.jar 时却出现了如下的一堆报错信息。

从上面报错信息中可以看出是因为缺少依赖而导致启动异常。一通谷歌之后最后确定只需要执行:apt -y install xvfb libxss1 libnss3 firefox,然后再运行:xvfb-run java -jar yourApplication.jar 就可以正常启动了。
