我正在开发 Spring MVC 项目。我直接使用休眠。No Session found for current thread我的项目中发生了错误。我知道在 stackoverflow 和网络上的其他地方，这个错误很常见。但我还没有找到解决我问题的有效方法。
我在正确配置 Hibernate 会话工厂时遇到了未解决的问题。我在这里进行了描述：我可以使用在 DispatcherServlet Context 中声明的 Hibernate Session Factory 而不是 hibernate.cfg.xml？但最后我使用的是hibernate.cfg.xml文件以及在 DispatcherServlet 上下文文件中定义的 Hibernate Session Factory。我做了一些简单的操作，比如在数据库中持久化类。一切都很好。
目前我的项目与Spring MVC Hibernate有很多共同点。我为我的类添加了一些注释，并创建了一些新的服务类。
我的 ServletDispatcher 上下文文件包含以下定义：
<annotation-driven />
<context:annotation-config />
<context:component-scan base-package="finances.webapp" />
<!-- Data source -->
<beans:bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
<beans:property name="driverClassName" value="com.mysql.jdbc.Driver" />
<beans:property name="url" value="jdbc:mysql://localhost/finances" />
<beans:property name="username" value="root" />
<beans:property name="password" value="root" />
</beans:bean>
<!-- Data source end -->
<!-- Hibernate session factory -->
<beans:bean id="sessionFactory" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">
<beans:property name="dataSource">
<beans:ref bean="dataSource" />
</beans:property>
<beans:property name="configLocation" value="classpath:hibernate.cfg.xml" />
</beans:bean>
<!-- Hibernate session factory end -->
<beans:bean id="transactionManager" class="org.springframework.orm.hibernate4.HibernateTransactionManager">
<beans:property name="sessionFactory" ref="sessionFactory" />
</beans:bean>
<beans:bean id="transactionInterceptor" class="org.springframework.transaction.interceptor.TransactionInterceptor">
<beans:property name="transactionManager" ref="transactionManager" />
<beans:property name="transactionAttributes">
<beans:props>
<beans:prop key="save">PROPAGATION_REQUIRED</beans:prop>
</beans:props>
</beans:property>
</beans:bean>
在我的 pom.xml 文件中，根据 ORM，我只有这两个依赖项：
<!-- Hibernate -->
<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-entitymanager</artifactId>
<version>4.1.4.Final</version>
</dependency>
<!-- EJB -->
<dependency>
<groupId>javax.ejb</groupId>
<artifactId>ejb-api</artifactId>
<version>3.0</version>
<scope>provided</scope>
</dependency>
也许问题就在这里？但是我之前缺少包裹没有任何问题。
这是来自我的控制器的代码：
UsersEntity user2 = new UsersEntity("qwerty", "qwerty", true);
usersService.addUser(user2);
No Session found for current thread调用addUser()方法时出现问题。
我的 DAO 课程：
@Repository
public class UsersHome {
@Autowired
private SessionFactory sessionFactory;
public void persist(UsersEntity transientInstance) {
sessionFactory.getCurrentSession().persist(transientInstance);
}
}
我的服务：
@Service
public class UsersService {
@Autowired
private UsersHome usersHome;
@Transactional(propagation = Propagation.REQUIRED)
public void addUser(UsersEntity user) {
usersHome.persist(user);
}
}
当我在UsersHome课堂上更改方法主体时，此代码已停止工作。以前我一直在我的行动之前开始会话，在我行动之后结束会话。但是使用注释和事务它应该工作吗？请给我一些建议。
