Java生成水印new Font(“黑体”,Linux环境下 中文乱码

Linux环境下"Font font = new Font(“黑体”, Font.BOLD, 18)"\[BufferedImageGraphicsdrawString\]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  
本地是windows  
线上是centos

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。

Windos下C:\\Windows\\Fonts\\simhei.ttf  
黑体文件。

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：

注：如果没有fonts目录可以手动创建，“windowsFonts”为自定义文件夹名称。

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web sever，例如：tomcat，字体生效！

注：在ubuntu中需要安装：apt-get install fontconfig，侯执行以下命令！  
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  
/usr/share/X11/fonts/Type1: skipping, no such directory  
/usr/share/X11/fonts/TTF: skipping, no such directory  
/usr/local/share/fonts: skipping, no such directory  
/root/.fonts: skipping, no such directory  
/var/cache/fontconfig: cleaning cache directory  
/root/.fontconfig: not cleaning non-existent cache directory  
fc-cache: succeeded  
或
