ssh环境搭建——spring与hibernate整合

首先分为三个部分，一：引入jar包。二：编写entity类dao类以及service类。三：引入.hbm.xml配置文件，编写公共类1.引入数据源2.创建sessionfactory2.1加载mappinglocation映射3.事务管理器3.1事务通知3.2aop配置4.测试

第一步：首先第一步引入jar包,在导入spring的jar包的同时导入如下hibernate的jar包

第二步：

1.实体类

package cn.itcast.pojo;


public class User {
private Long id;
private String userName;
private int age;
private String tel;
private  String Address ;
public Long getId() {
return id;
}
public void setId(Long id) {
this.id = id;
}
public String getUserName() {
return userName;
}
public void setUserName(String userName) {
this.userName = userName;
}
public int getAge() {
return age;
}
public void setAge(int age) {
this.age = age;
}
public String getTel() {
return tel;
}
public void setTel(String tel) {
this.tel = tel;
}
public String getAddress() {
return Address;
}
public void setAddress(String address) {
Address = address;
}
@Override
public String toString() {
return "User [id=" + id + ", userName=" + userName + ", age=" + age
+ ", tel=" + tel + ", Address=" + Address + "]";
}


}

2.dao类

public class UserDao extends HibernateDaoSupport implements IUserDao{


@Override
public void save(User user) {
getHibernateTemplate().save(user);

}


@Override
public void update(User user) {
getHibernateTemplate().update(user);

}


@Override
public void delete(Serializable id) {
User d=findById(id);
if(d!=null)
{
  getHibernateTemplate().delete(id);
}
}


@Override
public User findById(Serializable id) {

return getHibernateTemplate().get(User.class, id);
}

@Override
public List<User> getAll() {

return getHibernateTemplate().loadAll(User.class);
}

}

这里要注意的是继承了hibernateDaosupport类

3.service类

public class UserService implements IUserService {
   IUserDao userDao;
public IUserDao getUserDao() {
return userDao;
}


public void setUserDao(IUserDao userDao) {
this.userDao = userDao;
}


@Override
public void save(User user) {

userDao.save(user);
}


@Override
public void update(User user) {

userDao.update(user);
}


@Override
public void delete(Serializable id) {
userDao.delete(id);

}


@Override
public User findById(Serializable id) {

return userDao.findById(id);
}


@Override
public List<User> getAll() {

return userDao.getAll();
}


}

注意一定要给set方法

第三步

 <!-- 声明一个字符串 -->
<!-- 所有模块共用模块 -->
<!-- 1.数据源 -->

<property name="password" value="root"></property>
<property name="initialPoolSize" value="2"></property>
<property name="maxPoolSize" value="6"></property>

<!-- 2.spring对sessionfactory创建支持 -->
<!-- 普通配置 -->
<bean id="sessionFactory"
class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
<property name="dataSource" ref="dataSource"></property>
<property name="hibernateProperties">
<props>
<prop key="hibernate.dialect">org.hibernate.dialect.MySQLDialect</prop>
<prop key="hibernate.show_sql">true</prop>

</property>
</bean>

   <aop:advisor advice-ref="txAdvice" pointcut-ref="pt"/>
</aop:config>
 
</beans>     

同时引入

<import resource="bean-public.xml"/>
<import resource="bean-dao.xml"/>
<import resource="bean-service.xml"/>

四：测试

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration("/bean.xml")
public class Test_Spring_Hibernate{
    @Resource
private IUserService userService;
  @Test
public void save() {
User user=new User();
user.setId(1L);
user.setAge(10);
user.setTel("13423567834");
user.setAddress("东北大学");
user.setUserName("zxl");
userService.save(user);
}

}
