十四、Spring中hibernateTemplate的使用
最后更新于：2022-04-01 11:38:35
HibernateTemplate的配置和使用：
1、配置bean文件：因为要用到sessionFactory索性就都复制了过来.也方便大家看

<!-- placeholder 占位符 -->

</bean>
<!-- 配置dataSource -->

<property name="url" value="${jdbc.url}" />
<property name="username" value="${jdbc.username}" />
<property name="password" value="${jdbc.password}" />
</bean>
<!-- 将配置好的dataSource注入到SessionFactory中-->
<bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
<property name="dataSource" ref="dataSource"/>
<property name="mappingResources">
<list>
<value>com/spring/model/user.hbm.xml</value>

<property name="hibernateProperties">
<value>
hibernate.dialect=org.hibernate.dialect.MySQLDialect
hibernate.show_sql=true
hibernate.hbm2ddl.auto=create
</value>
</property>
</bean>
<!-- 声明式事务管理,事务需要数据源，从sessionFactory中拿到
这是一个AOP的应用 -->
<bean id="transactionManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager">
<property name="sessionFactory" ref="sessionFactory" />
</bean>
<!-- 配置事务要管理的方法 -->
<tx:advice transaction-manager="transactionManager" id="txManager">
<tx:attributes>
<tx:method name="save"/>
</tx:attributes>
</tx:advice>
<!-- 配置aop设置切面和织入点逻辑 -->
<aop:config>
<aop:pointcut id="entryPointMethod" expression="execution(public * com.spring.service..*.*(..))"/>
<aop:advisor
advice-ref="txManager"
pointcut-ref="entryPointMethod"
/>
</aop:config>
<!-- 配置一个hibernateTemplate -->
<bean id="hibernateTemplate" class="org.springframework.orm.hibernate3.HibernateTemplate">
<property name="sessionFactory" ref="sessionFactory"></property>
</bean>
</beans>

2、使用@resource注入,然后调用save方法:
~~~
@Component("userDaoImpl")
public class UserDaoImpl implements UserDao{
@Resource
private HibernateTemplate hibernateTemplate;
public HibernateTemplate getHibernateTemplate() {
return hibernateTemplate;
}
public void setHibernateTemplate(HibernateTemplate hibernateTemplate) {
this.hibernateTemplate = hibernateTemplate;
}
@Override
public void save(User u) {
try {
hibernateTemplate.save(u);
} catch (HibernateException e) {
e.printStackTrace();
}
}
}
