api 的接口

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

provider

public class SumService implements ISumService {@Overridepublic 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();} }
