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 com.spring.service.DogPetService;import com.spring.dao.DogPetDAO;import com.spring.model.DogPet;public class DogPetServiceImpl implements DogPetService{        private DogPetDAO dogPetDAO;    public DogPetDAO getDogPetDAO() {        return dogPetDAO;    }        @Resource(name="dogPetDAO1")    public void setDogPetDAO(DogPetDAO dogPetDAO) {        this.dogPetDAO = dogPetDAO;    }    @Override    public void queryAllDogPets() {        List
     
       list = dogPetDAO.queryAllDogPets();        if(list != null)        {            for(DogPet d:list)            {                System.out.println(d.toString());            }        }    }        }
     

Service的调用DAO类：

package com.spring.dao;import java.util.ArrayList;import java.util.List;import com.spring.model.DogPet;public class DogPetDAO {        public List
     
       queryAllDogPets()    {        List
      
        list = new ArrayList
       
        ();                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;    }}
       
      
     

配置文件:

test类：

package com.spring.test;import org.junit.Test;import org.springframework.context.ApplicationContext;import org.springframework.context.support.ClassPathXmlApplicationContext;import com.spring.service.DogPetService;public class ResourceTest {        @Test    public  void queryAllDogPets()    {        ApplicationContext ctx = new ClassPathXmlApplicationContext("beans.xml");        DogPetService dogPetService = (DogPetService)ctx.getBean("dogPetService");        dogPetService.queryAllDogPets();    }}
