2016-10-11 19:35:49.724 sun.management.Agent error System.err: 错误: 代理抛出异常错误 2016-10-11 19:35:49.726 sun.management.Agent error System.err: : java.net.MalformedURLException: Local host name unknown: java.net.UnknownHostException: xiaoming-macbook.local: xiaoming-macbook.local: nodename nor servname provided, or not known Disconnected from server

解决方案：

打开/etc/hosts 文件 增加127.0.0.1 xiaoming-macbook.local
