1.客户端是否有进行配置.例如:

<bean id="smsRMI" class="org.springframework.remoting.rmi.RmiProxyFactoryBean">
    <property name="serviceUrl" value="rmi://localhost:1099/smsService"/>
    <property name="serviceInterface" value="com.service.SmsService"/>
    <property name="lookupStubOnStartup" value="false"/>
    <property name="refreshStubOnConnectFailure" value="true"/>
</bean>

2.客户端调用时是否有加载相关配置文件.例如:

ApplicationContext context = new ClassPathXmlApplicationContext("spring-config-client.xml");
SmsService smsService = (SmsService) context.getBean("smsRMI");
