以上是二维码加字 logo的代码本地测试没问题但是部署到linux服务器上出现问题：

could not initialize class sun.awt.X11FontManager 问题的思考:
首先我本地是没问题的部署到linux服务器上有问题百度了一下相关，首先猜想是服务器上缺少字体文件，
随后从本地拿了宋体文件添加到服务器，复制到linux的/usr/share/fonts文件夹下面，然后运行fc-cache -fv命令将字体重载一下
source /etc/profile 或者reboot重启服务器
查看字体为中文的 fc-list :lang=zh
但是graphics.drawstring()仍然报错
这次报的是Handler processing failed; nested exception is java.lang.UnsatisfiedLinkError: /data/env/jdk1.7.0_80/jre/lib/i386/libfontmanager.so
百度相关可能是jdk版本冲突查看了linux为64位 jdk为32位估计问题在这重新安装了64位的jdk 问题得以解决
