Linux环境下"Font font = new Font("黑体", Font.BOLD, 18)"[BufferedImage~Graphics~drawString]中文乱码,windows下不会乱码,但在linux下nginx和tomcat部署后出现乱码、方框、问号等等，不能认清楚！！！
先说说系统：
Microsoft Windows [版本 10.0.10586]
(c) 2015 Microsoft Corporation。保留所有权利。
----------------------------------------------------------------------
CentOS release 6.5 (Final)
Kernel \r on an \m
----------------------------------------------------tomcat 8.0.28
好了，说怎么解决的吧步骤：
1：查看CentOS下”/usr/share/fonts“目录，查看新的系统则为空目录；无目录可手动创建fonts。
2：打开”C:\Windows\WinSxS\amd64_microsoft-windows-font-truetype-simsunb_31bf3856ad364e35_10.0.10586.0_none_1d80224ec6470747“等目录下，找到自己需要的字体的目录，那个文件夹也是见名知意了；
3：之后把挑选的字体，可以建个文件夹，一次传到Xftp等上传到服务器的”/usr/share/fonts“的目录下；
4：进入"cd /usr/share/fonts/windowsFonts"文件夹，注：windowsFonts为我挑选字体目录：
有楷体，黑体，简宋体，微软雅黑等，最后附上！
5：最后在此目录下，执行"#fc-cache -fv"，扫描字体目录并生成字体信息的缓存，然后应用程序就可以"立即"使用这些新安装的字体；
6：最终还是要重启tomcat了，字体生效！
执行命令 fc-cache -fv：
[root@timespacexstar windowsFonts]# fc-cache -fv
/usr/share/fonts: caching, new cache contents: 0 fonts, 1 dirs
/usr/share/fonts/windowsFonts: caching, new cache contents: 8 fonts, 0 dirs

或

/var/cache/fontconfig: cleaning cache directory
/root/.cache/fontconfig: not cleaning non-existent cache directory

包涵字体：
