docker环境hosts配置错误导致的tomcat无法正常启动
1 问题描述项目部署在linux（包括虚拟机）环境、window环境是上，tomcat启动正常，但是在迁移到docker环境，出现服务无法正常启动现象。
2 异常描述
2.1 应用日志
总结来说日志中体现的是重复加载，表现形式如下：
1)定时器重复
ERROR com.*.acl.schedule.quartz.BaseQuartz(75) 启动com.*.acl.schedule.job.PowerInterceptVerifyJob
异常
org.quartz.ObjectAlreadyExistsException:Unable to store Job : 'PowerInterceptVerifyGroup.PowerInterceptVerifyJob',because one already exists with this identification.
2)类重复初始化
2016-08-2618:33:01,415 INFOcom.*.acl.common.constant.PowerHolder(62) 初始化powerHolder
2016-08-2618:33:03,350 INFOcom.*.acl.common.constant.RuleHolder(45) 初始化RuleHolder
2016-08-2618:33:03,355 INFOcom.*.acl.common.constant.RuleHolder(70) 初始化ruleHolder耗时5毫秒,加载数据3个
2016-08-2618:33:03,437 INFOcom.*.acl.common.constant.PowerHolder(62) 初始化powerHolder
2016-08-2618:33:06,895 INFOcom.*.acl.common.constant.PowerHolder(94) 初始化powerHolder耗时5480毫秒,加载数据3253个
2016-08-2618:33:06,897 INFOcom.*.acl.service.impl.AsyncAclServiceImpl(113) 计数器总数=0
2.2 tomcat日志
localhost.log异常如下：
Aug 29, 2016 7:12:24 PM org.apache.catalina.core.StandardContextloadOnStartup
SEVERE: Servlet in web application []threw load() exception
java.net.UnknownHostException: c01.test.aclservice.hgh.*.com: Name orservice not known
at java.net.Inet6AddressImpl.lookupAllHostAddr(Native Method)
at java.net.InetAddress$1.lookupAllHostAddr(InetAddress.java:901)
3 解决方案
按照tomcat的错误提醒，配置正确的hosts
