起因
最近写一个项目,之前在eclipse里的tomcat启动是没问题的,最近不知怎么了,启动的时候ehcache会报一个错误,说java.net.UnknownHostException: bogon: bogon: nodename nor servname provided, or not known.下面是错误日志的全部内容:
11:46:56,905 ERROR localhost-startStop-1 [net.sf.ehcache.Cache:202] - Unable to set localhost. This prevents creation of a GUID. Cause was: bogon: bogon: nodename nor servname provided, or not known

虽然报错了,但是不影响程序正常使用.
解决
这个bogon怎么都没找到我的程序里哪里有这个东西.网上查了一下,好像和路由映射有关系.最后查一篇文章,说这个问题只有mac会遇到.处理方法就是对bogon做个DNS解析指向127.0.0.1.
修改文件/etc/hosts,在里面增加对127.0.0.1的解析.
127.0.0.1 bogon localhost
保存生效后,再启动tomcat就没这个问题了.
