public class House {

    private String id;

    private String name;

    private String address;

    public String getId() {

        return id;

    }

    …//其它

经理写接口：

public interface HouseService {

    public List<House> getAllHouses();

}

小弟写实现类：

@Override

    public List<House> getAllHouses() {

        List<House> houseList = new ArrayList<House>();

        //1    光头强的家    森林188号

        //2    熊大的家    森林树洞一期3楼

        House h1 = new House();

        House h2 = new House();

        h1.setId("1");

        h1.setName("光头强的家");

        h1.setAddress("森林188号");

        h2.setId("2");

        h2.setName("熊大的家");

        h2.setAddress("森林树洞一期3楼");

        houseList.add(h1);

        houseList.add(h2);

        return houseList;

    }
