实体类:
package com.spring.model; import javax.persistence.Entity; import javax.persistence.Id; import javax.persistence.Table; @Entity @Table(name="t_dog") public class DogPet { private int id; private String name; private int age; private String kind; private String sex; private String health; @Id 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.Controller; import com.spring.service.DogPetService; import com.spring.dao.DogPetDAO; import com.spring.model.DogPet; @Controller(value="DogPetService") public class DogPetServiceImpl implements DogPetService{ private DogPetDAO dogPetDAO; public DogPetDAO getDogPetDAO() { return dogPetDAO; } @Resource(name="dogPetDAO") 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:
package com.spring.dao; import java.util.List; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.beans.factory.annotation.Qualifier; import org.springframework.orm.hibernate3.HibernateTemplate; import org.springframework.stereotype.Component; import com.spring.model.DogPet; @Component public class DogPetDAO { private HibernateTemplate hibernateTemplate; public List<DogPet> queryAllDogPets() { List<DogPet> list = hibernateTemplate.find("from DogPet"); return list; } public HibernateTemplate getHibernateTemplate() { return hibernateTemplate; } @Autowired public void setHibernateTemplate(@Qualifier(value="hibernateTemplate") HibernateTemplate hibernateTemplate) { this.hibernateTemplate = hibernateTemplate; } }
