api 的接口

public interface ISumService {
    Integer sum(Integer a,Integer b);
}

provider

public class SumService implements ISumService {
    @Override
    public Integer sum(Integer a, Integer b) {
        return a+b;
    }
}

public class App 
{
    public static void main( String[] args ) throws IOException {
        ClassPathXmlApplicationContext context=
                new ClassPathXmlApplicationContext("dubbo-server.xml");
        context.start();

        System.in.read();

    }
}
