实体类：

package com.spring.model;

public class DogPet {

    private int id;
    private String name;
    private int age;
    private String kind;
    private String sex;
    private String health;
    public int getId() {
        return id;
    }
    public void setId(int id) {
        this.id = id;
    }
    public String getName() {
        return name;
    }
    public void setName(String name) {
        this.name = name;
    }
    public int getAge() {
        return age;
    }
    public void setAge(int age) {
        this.age = age;
    }
    public String getKind() {
        return kind;
    }
    public void setKind(String kind) {
        this.kind = kind;
    }
    public String getSex() {
        return sex;
    }
    public void setSex(String sex) {
        this.sex = sex;
    }
    public String getHealth() {
        return health;
    }
    public void setHealth(String health) {
        this.health = health;
    }

    public String toString()
    {
        return id+"--"+name+"--"+kind+"--"+age+"--"+health;
    }
}

接口Service：

package com.spring.service;

public interface DogPetService {
    public void queryAllDogPets();
}

实现类ServiceImpl：

package com.spring.service.impl;

import java.util.List;

import javax.annotation.Resource;

import org.springframework.stereotype.Service;

import com.spring.service.DogPetService;
import com.spring.dao.DogPetDAO;
import com.spring.model.DogPet;

@Service("dogPetService")
public class DogPetServiceImpl implements DogPetService{

    private DogPetDAO dogPetDAO;

    public DogPetDAO getDogPetDAO() {
        return dogPetDAO;
    }

    @Resource(name="dogPetDAO2")
    public void setDogPetDAO(DogPetDAO dogPetDAO) {
        this.dogPetDAO = dogPetDAO;
    }

    @Override
    public void queryAllDogPets() {
        List<DogPet> list = dogPetDAO.queryAllDogPets();
        if(list != null)
        {
            for(DogPet d:list)
            {
                System.out.println(d.toString());
            }
        }
    }

}

Service调用的DAO类：

package com.spring.dao;

import java.util.ArrayList;
import java.util.List;

import org.springframework.stereotype.Service;

import com.spring.model.DogPet;

@Service(value="dogPetDAO2")
public class DogPetDAO {

    public List<DogPet> queryAllDogPets()
    {
        List<DogPet> list = new ArrayList<DogPet>();

        DogPet d1 = new DogPet();
        d1.setId(1111);
        d1.setName("dog1");
        d1.setAge(4);
        d1.setKind("buladuo");
        d1.setSex("B");
        d1.setHealth("good");
        DogPet d2 = new DogPet();
        d2.setId(2222);
        d2.setName("dog2");
        d2.setAge(3);
        d2.setKind("buladuo");
        d2.setSex("G");
        d2.setHealth("good");

        list.add(d1);
        list.add(d2);

        return list;
    }
}
