是因为使用的JDK不支持awt包下的字体

解决方法：

• 安装FontConfig组件即可

• 在线

yum install -y fontconfig
# 查看安装结果
fc-list
ls  /etc/fonts/
# 重启应用

• 离线

# 按顺序安装 rpm
rpm -ivh  fontpackages-filesystem-1.44-8.el7.noarch.rpm
rpm -ivh  dejavu-fonts-common-2.33-6.el7.noarch.rpm
rpm -ivh  dejavu-sans-fonts-2.33-6.el7.noarch.rpm
rpm -ivh  fontconfig-2.13.0-4.3.el7.x86_64.rpm
# 查看安装结果
fc-list
ls  /etc/fonts/
# 重启应用 todo yzd
