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<DogPet> 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<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;
}
}
