在更改会话的访问方法后，“找不到当前线程的会话”
我正在开发Spring MVC项目。 我直接使用Hibernate。 在我的项目中发生No Session found for current thread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问题的方法。
正确配置Hibernate Session Factory时遇到了未解决的问题。 我在这里描述过： 我可以使用在DispatcherServlet Context中声明的Hibernate Session Factory而不是hibernate.cfg.xml吗？ 但最后我使用的是hibernate.cfg.xml文件以及DispatcherServlet Context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。
此时我的项目与Spring MVC Hibernate有很多共同之处。 我在我的类中添加了一些注释，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：
PROPAGATION_REQUIRED
在我的pom.xml文件中，根据ORM，我只有这两个依赖项：
org.hibernate hibernate-entitymanager 4.1.4.Final javax.ejb ejb-api 3.0 provided
也许问题在这里？ 但是我之前没有丢包的问题。
这是我的控制器的代码：
UsersEntity user2 = new UsersEntity("qwerty", "qwerty", true); usersService.addUser(user2);
在调用addUser()方法期间No Session found for current thread的问题。
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类中更改方法体时，此代码已停止工作。 以前我在行动之前开始会议，在我的行动结束后开始会议。 但是使用注释和交易应该有用吗？ 请给我一些建议。

我的root-context.xml文件：
我的整个spring-config.xml文件：
<!----> <!----> <!----> <!--/WEB-INF/tiles-definitions.xml--> <!----> <!----> <!----> <!----> <!----> <!----> PROPAGATION_REQUIRED PROPAGATION_REQUIRED
尝试删除“transactionInterceptor”，您已经设置了@Transaction属性，并且还有标记persist()方法添加到transactionInterceptor键
PROPAGATION_REQUIRED
也许它有帮助。
编辑：我重新创建了您的配置，它的工作原理。
这个spring配置：
这是hibernate配置：
org.hibernate.dialect.H2Dialect true update
pom.xml中的依赖项
3.1.0.RELEASE 4.1.4.Final org.hibernate hibernate-entitymanager ${org.hibernate.version} org.hibernate hibernate-core ${org.hibernate.version} org.hibernate hibernate-annotations 3.5.6-Final javax.ejb ejb-api 3.0 provided org.springframework spring-core ${org.springframework.version} org.springframework spring-context ${org.springframework.version} org.springframework spring-tx ${org.springframework.version} org.springframework spring-jdbc ${org.springframework.version} org.springframework spring-orm ${org.springframework.version} org.springframework spring-aop ${org.springframework.version} org.springframework spring-webmvc ${org.springframework.version} cglib cglib 2.2.2 com.h2database h2 1.3.168 org.testng testng 6.1.1 test
unit testing：
public class TestPersist { @org.testng.annotations.Test public void testPersistence() throws Exception { ApplicationContext ctx = new ClassPathXmlApplicationContext("spring-context.xml"); Assert.assertNotNull(ctx); UsersService userService = ctx.getBean(UsersService.class); Assert.assertNotNull(userService); UsersEntity user2 = new UsersEntity(); user2.setEnable(true); user2.setLogin("querty"); user2.setName("user2"); userService.addUser(user2); } }
和unit testing输出：
