既然是开发案例，显然不会扯那么多老婆舌，有不清楚这两个东东的请自行百度。
开发环境
JDK1.7、Maven、Eclipse、SpringBoot1.5.1、Dubbo2.8.4
项目结构

User.java 一定要实现序列化接口
public class User implements Serializable {
private static final long serialVersionUID = -1L;
private String username;
private Integer age;
public User(String username, Integer age) {
this.username = username;
this.age = age;
}
public String getUsername() {
return username;
}
public void setUsername(String username) {
this.username = username;
}
public Integer getAge() {
return age;
}
public void setAge(Integer age) {
this.age = age;
}
}
IUserService.java 接口
public interface IUserService {
void saveUser(User user);
}
UserServiceImpl.java 实现
@Service("userService")
public class UserServiceImpl implements IUserService {
@Override
public void saveUser(User user) {
System.out.println("保存用户:"+user.getUsername());
}
}

SpringbootDubboApplication.java 测试类
@SpringBootApplication
@ComponentScan(basePackages={"com.itstyle.dubbo"})
@ImportResource({"classpath:dubbo.xml"})
public class SpringbootDubboApplication implements CommandLineRunner {
@Autowired
private IUserService userService;
public static void main(String[] args) {
SpringApplication.run(SpringbootDubboApplication.class, args);
}
@Override
public void run(String... args) throws Exception {
User user = new User("张三",19);
userService.saveUser(user);
}
}此时，我们运行SpringbootDubboApplication类，如下结果说明成功：
然后使用ZooInspector查看zookeeper信息，会发现注册了一个提供者：
