我们的项目用到了xmlrpc,不过还是用的2.x版本的。由于xmlrpc3.x地推出。提供了NULL,Serializable等的支持，将原来的Hashtable改成了Map,Vector改成了List。都是不错的进步。所以我们决定从xmlrpc2.x升级到xmlrpc3.x.
在spring里面有几个ServiceExporter，org.springframework.remoting.rmi.RmiServiceExporter、org.springframework.remoting.caucho.HessianServiceExporter、org.springframework.remoting.caucho.BurlapServiceExporter。不过没有xmlrpc的serviceExporter，原来我们是自己封装的XmlRpcServer,用servlet提供服务。(eg:http://localhost:8080/community/service/xmlrpc)没有和spring集成虽然用了spring。
考虑到spring的便利以及配置的同意我决定将xmlrpcService放入spring中。xmlrpc3.x和xmlrpc2.x的代码基本上没有一样的。改了很多东西。除了类型变化之外，还添加了对异常的支持。详细信息请参照xmlrpc3.x源代码。

spring配置文件
<bean id="accountService" class="com.jdkcn.service.impl.AccountServiceImpl">
</bean>
<bean name="rpcAccountService" class="com.jdkcn.xmlrpc.XmlRpcServiceExporter">
<property name="service">
<ref bean="accountService"/>
</property>
<property name="serviceName">
<value>jdkcn.accountService</value>
</property>
<property name="enabledForExtensions">
<value>true</value>
</property>
<property name="serviceInterface">
<value>com.jdkcn.service.AccountService</value>
</property>
</bean>然后映射一个地址就可以通过xmlrpc访问服务了
<bean id="urlMapping" class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping">
<property name="mappings">
<props>
<prop key="/account">rpcAccountService</prop>
</props>
</property>
</bean>
web.xml
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>
classpath:spring/global.xml
</param-value>
</context-param>
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
<servlet>
<servlet-name>service</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>service</servlet-name>
<url-pattern>/service/xmlrpc3/*</url-pattern>
</servlet-mapping>
然后我们的service地址就是这样的http://localhost:8080/service/xmlrpc3/account
