??????我們的項(xiàng)目用到了xmlrpc,不過還是用的2.x版本的。由于xmlrpc3.x地推出。提供了NULL,Serializable等的支持，將原來的Hashtable改成了Map,Vector改成了List。都是不錯(cuò)的進(jìn)步。所以我們決定從xmlrpc2.x升級(jí)到xmlrpc3.x.
??????在spring里面有幾個(gè)ServiceExporter，org.springframework.remoting.rmi.RmiServiceExporter、org.springframework.remoting.caucho.HessianServiceExporter、org.springframework.remoting.caucho.BurlapServiceExporter。不過沒有xmlrpc的serviceExporter，原來我們是自己封裝的XmlRpcServer,用servlet提供服務(wù)。(eg:http://localhost:8080/community/service/xmlrpc)沒有和spring集成雖然用了spring。
??? 考慮到spring的便利以及配置的同意我決定將xmlrpcService放入spring中。xmlrpc3.x和xmlrpc2.x的代碼基本上沒有一樣的。改了很多東西。除了類型變化之外，還添加了對(duì)異常的支持。詳細(xì)信息請(qǐng)參照xmlrpc3.x源代碼。

然后我們的service地址就是這樣的http://localhost:8080/service/xmlrpc3/account
希望對(duì)大家有用，這里提供project下載。包含一個(gè)client程序。com.jdkcn.xmlrpc.Client
點(diǎn)擊下載完整代碼
