Caused by: java.net.UnknownHostException: localhost.localdomain: localhost.localdomain的问题解决

在hosts文件增加如下配置即可，下面的方法适合上面提示的错误，无论是Tomcat问题还是MongoDB等等的问题都可以完美解决。

vi /etc/hosts
127.0.0.1       localhost localhost.localdomain localhost4 localhost4.localdomain4 
127.0.0.1       localhost localhost.localdomain localhost6 localhost6.localdomain6
