Hibernate cannot work without transaction. Preferred way to use a transaction manager.
没有事务，Hibernate 无法工作。使用事务管理器的首选方式。
Easy way to just call
打电话的简单方法
session.beginTransaction();
Criteria crit = session.createCriteria();
crit.list();
session.getTransaction().commit();
回答by Suganthan Madhavan Pillai
If you missed out this line in your code please add before writing criteria query
如果您错过了代码中的这一行，请在编写标准查询之前添加
Transaction tx = session.beginTransaction();
finally
最后
tx.commit();

DAO implementation beans are usually annotated with @Repository. In your case you are used a @Component. This stereotype doesn't have a transaction support.
DAO 实现 bean 通常用@Repository. 在您的情况下，您使用的是@Component. 这种构造型没有事务支持。
Communication with the database using Hibernate is made in the scope of transaction. An open current transaction is required to perform database operations.
使用 Hibernate 与数据库的通信是在事务范围内进行的。需要一个打开的当前事务来执行数据库操作。
Configuration fixes:
配置修复：
<bean id="txManager" class="org.springframework.orm.hibernate4.HibernateTransactionManager">
<property name="sessionFactory" ref="sessionFactory"/>
</bean>
and if you use tx:annotation-driventag then you have to annotate your methods or classes with @Transactionalannotation.
如果你使用tx:annotation-driven标签，那么你必须用注释来注释你的方法或类@Transactional。

getCurrentSession(): Obtains the current session.
getCurrentSession(): 获取当前会话。
Creates a new session, different from the contextual session
创建一个新的会话，不同于上下文会话
openSession(): Returns: The created session.
openSession(): 返回： 创建的会话。
回答by Ashutosh S
Steps needed :
需要的步骤：
Get session in this way :
Session session = HibernateUtil.getSessionFactory().getCurrentSession();Intialize Transaction
Transaction tx = session.beginTransaction();- Write Criteria to fetch list from Database.
Close the initialized transaction.
tx.close();
以这种方式获取会话：
Session session = HibernateUtil.getSessionFactory().getCurrentSession();初始化事务
Transaction tx = session.beginTransaction();- 写入标准以从数据库中获取列表。
关闭初始化的事务。
tx.close();
