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; }}

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
