验证码报错

org.springframework.web.util.NestedServletException: Handler dispatch failed; nested exception is java.lang.InternalError: java.lang.reflect.InvocationTargetException

往下看是否有如下异常信息

Caused by: java.lang.NullPointerException: null
at java.desktop/sun.awt.FontConfiguration.getVersion(FontConfiguration.java:1262) ~[na:na]

如果有

解决 安装字体

yum install fontconfig
fc-cache
