注意事項(xiàng)
1.服務(wù)接口要繼承java.rmi.Remote接口田篇，聲明方法必須 throws
java.rmi.RemoteException，否則會(huì)拋異常
2.接口實(shí)現(xiàn)類(lèi)繼承UnicastRemoteObject類(lèi)箍铭，構(gòu)造方法需要throws RemoteException泊柬，同時(shí)將實(shí)現(xiàn)類(lèi)聲明為public
3.實(shí)現(xiàn)類(lèi)最好實(shí)現(xiàn)Serializable接口，實(shí)現(xiàn)方法中throws java.rmi.RemoteException
