普通接口与实现类
public interface DemoService
{
String sayHello(String msg);
}
public class DemoServiceImpl implements DemoService
{
@Override
public String sayHello(String msg)
{
return "hello " + msg;
}
}

</beans>dubboRMI与springRMI相互调用注意点
端口须匹配
<dubbo:service path="hello"> 与 springRMI配置<property name="serviceName" value="hello" /> 要一致, dubbo默认为接口全路径
