字体的问题，翻看日志，分析日志，
下面三行报错代码：
java.awt.Font[family=Dialog,name=Bell MT,style=bold,size=50]
java.awt.Font[family=Dialog,name=Credit valley,style=italic,size=50]
java.awt.Font[family=Dialog,name=Bell MT,style=plain,size=50]
java.awt.Font[family=Dialog,name=Credit valley,style=plain,size=50]
java.awt.Font[family=Dialog,name=Credit valley,style=bold,size=50]
然后把name的三个字体在windows下找到，放到centos下，在/usr/share/fonts/ 下创建三个目录，分别把三个字体的文件存放进去，然后执行 fc-cache 重新加载字体；
[root@bogon fonts]# pwd
/usr/share/fonts
[root@bogon fonts]# ls
arial lyx tahoma Verdana
[root@bogon fonts]# fc-cache
问题解决，如果自己的电脑上找不到字体，去百度然后下载下来
