org.quartz.SchedulerException: Couldn't get host name!

最近遇到一个问题，部署在服务器上的web项目启动的时候报错了

开始的时候还以为是项目中的配置错了才导致的，跟定时器有关系，然后把定时器注释掉了，发现问题还是存在

经过百度查询了之后，发现是服务器的配置出了错误，当初搭建服务器的时候没注意到，有两个配置文件里面少了参数
第一个文件：HOSTS，路径：vi /etc/hosts 下添加主机名称 ：ZHBA-DB

127.0.0.1   localhost  ZHBA-DB

第二个文件
网卡配置 ifcfg-eth0， 路径 vi /etc/sysconfig/network-scripts/ifcfg-eth0，添加以下参数

HOSTNAME=ZHBA-DB

然后项目正常启动完成
