启动idea加载pom时，readingmavenprojectreadingpom.xml

现象：

启动idea加载pom时，reading maven project reading pom.xml

原因：

在idea的help菜单下点击，show log in finder,看日志，无法链接网路（实际正常）

java.net.ConnectException: Connection refused

继续看日志，maven无法请求localhost

java.rmi.RemoteException: Cannot start maven service; nested exception is: 

java.rmi.ConnectException: Connection refused to host: localhost; nested exception is: 

java.net.ConnectException: Connection refused 

解决：

hosts，添加 127.0.0.1 localhost
