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.Component; import com.spring.service.DogPetService;
import com.spring.dao.DogPetDAO;
import com.spring.model.DogPet; @Component("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.Component; import com.spring.model.DogPet; @Component("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;
}
}
