解决Linux下图片水印乱码以及生成PDF乱码问题

1 问题定位

windows下面无问题，在linux下面出现问题，中文变成方框，经过排查发现linux下缺少字体，只需将widows字体上传到linux服务器进行配置加载就好

2 解决方案

2.1 方案一

2.1.1 安装字体库

[root@localhost ~]# yum -y install fontconfig

2.1.2 新建目录

[root@localhost ~]# /usr/share/fonts
 [root@localhost fonts]# mkdir chinese
 [root@localhost ~]# cd chinese

2.1.2 上传Windows字体文件

将C:\Windows\Fonts下面的所有文件，上传到服务器的/usr/share/fonts/chinese目录下

[root@localhost chinese]# ll
 total 185340
 -rwxr-xr-x 1 root root 980756 Jan 20 16:10 arialbd.ttf
 -rwxr-xr-x 1 root root 721144 Jan 20 16:10 arialbi.ttf
 -rwxr-xr-x 1 root root 717428 Jan 20 16:10 ariali.ttf
 -rwxr-xr-x 1 root root 1036584 Jan 20 16:10 arial.ttf
 -rwxr-xr-x 1 root root 167592 Jan 20 16:10 ariblk.ttf
 -rwxr-xr-x 1 root root 40340 Jan 20 16:10 Arvo-Regular.ttf
 -rwxr-xr-x 1 root root 131660 Jan 20 16:10 AxureHandwriting-BoldItalic.otf

 -rwxr-xr-x 1 root root 229408 Jan 20 16:10 comicbd.ttf

2.1.3 安装字体

[root@localhost chinese]# yum -y install ttmkfdir 

2.1.4 刷新字体缓存

进行这个操作之后，就不用重启机器了

[root@localhost chinese]# fc-cache

2.1.5 查看安装字体

[root@localhost ~]# fc-list

2.2 方案二

2.2.1 JDK目录

JDK目录 /opt/module/jdk1.8.0_144

[root@localhost jre]# echo $JAVA_HOME
 /opt/module/
 [root@localhost jre]# cd /opt/module/
 [root@localhost module]# ll
 total 12
 drwxr-xr-x 7 root root 4096 Jul 22 2017 jdk1.8.0_144
 [root@localhost module]#

2.2.2 创建目录

[root@localhost jre]# cd /opt/module/jdk1.8.0_144/jre/lib/fonts
 [root@localhost fonts]# mkdir fallback
 [root@localhost fonts]# cd fallback

2.2.3 上传Windows字体文件

将C:\Windows\Fonts下面的所有文件，上传到服务器的/opt/module/jdk1.8.0_144/jre/lib/fonts/fallback目录下

[root@localhost fallback]# ll
 total 185340
 -rwxr-xr-x 1 root root 980756 Jan 20 16:10 arialbd.ttf
 -rwxr-xr-x 1 root root 721144 Jan 20 16:10 arialbi.ttf
 -rwxr-xr-x 1 root root 717428 Jan 20 16:10 ariali.ttf
 -rwxr-xr-x 1 root root 1036584 Jan 20 16:10 arial.ttf
 -rwxr-xr-x 1 root root 167592 Jan 20 16:10 ariblk.ttf

 -rwxr-xr-x 1 root root 322864 Jan 20 16:10 bahnschrift.ttf
 -rwxr-xr-x 1 root root 229408 Jan 20 16:10 comicbd.ttf

2.3 方案三

如果能确定项目中使用的字体对应的字体文件，只需上传单个文件，比如宋体 对应的字体文件就是 simsun.ttc，这样只需操作一个文件的上传就可以完成问题解决

3 重启服务

重启应用服务，比如tomcat等
