    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;
        }
    }
