Spring Transaction Hibernate @Transaction 注解不适用于@Autowired

Question

Spring Transaction Hibernate @Transaction 注解无法正确使用 @Autowired。如果我创建Dao`` element byxml(UserDao2 userDao2)`，

Service 类中的事务注解正在工作，如果它在尝试 getCurrentSesion 时通过 Dao 类中的 @Repository 注解表示：

org.hibernate.HibernateException: No Session found for current thread
    at org.springframework.orm.hibernate4.SpringSessionContext.currentSession(SpringSessionContext.java:97) ~[spring-orm-3.2.8.RELEASE.jar:3.2.8.RELEASE]
    at org.hibernate.internal.SessionFactoryImpl.getCurrentSession(SessionFactoryImpl.java:993) ~[hibernate-core-4.2.11.Final.jar:4.2.11.Final]

看来@Transactional 注释与会话工厂的链接不好

库版本：

<jdk.version>1.6</jdk.version>
<spring.version>3.2.8.RELEASE</spring.version>
<spring.security.version>3.2.3.RELEASE</spring.security.version>
<hibernate.version>4.2.11.Final</hibernate.version>

UserDao2（如果我通过 xml 创建 @Repository，我会删除它）

@Repository
public class UserDao2Impl implements UserDao2 {
  private static Logger log = LoggerFactory.getLogger(UserDao2Impl.class);

  @Autowired
  @Qualifier("sesionHibernate")
  private SessionFactory sesionHibernate;

  @SuppressWarnings("unchecked")
  public Usuario findByUserName(String username) {
    try {
      log.info("findByUserName" + sesionHibernate);

      List<Usuario> users = new ArrayList<Usuario>();
      System.out.println(sesionHibernate+"\n----------");

      users = sesionHibernate.getCurrentSession().createQuery("from Usuario where nombre=?").setParameter(0, username).list();
      // users = sesionHibernate.getCurrentSession().createQuery("from Usuario
      // where nombre=?").setParameter(0, username).list();

      if (users.size() > 0) {
        return users.get(0);
      } else {
        return null;
      }

    } catch (Exception e) {
      log.error("findByUserName ", e);
      return null;
    }
  }

Usuario2ServiceImpl如果有@Transacional的服务

@Service 
@Transactional
public class Usuario2ServiceImpl implements Usuario2Service {
  private static Logger log = LoggerFactory.getLogger(Usuario2ServiceImpl.class);

  //Qualifier("userDaoImpl")
  @Autowired
  private UserDao2 userDao2;       

  @Override
  public com.web.entity.Usuario getUsuariodetalles(final String nombreUsuario) throws UsernameNotFoundException {
    log.info("getUsuariodetalles - 1");
    System.out.println("ssss"+userDao2);
    com.web.entity.Usuario usuario = userDao2.findByUserName(nombreUsuario);    

    log.info("getUsuariodetalles - 2");
    return usuario;   
  }

Answer 1

您是否尝试将@Transactional 注释放在服务层方法中，您已将其放在类上。我认为它应该工作。

Answer 2

我在 Tomcat 中通过在下一行输入 spring-database.xml 解决了这个问题：

<context:load-time-weaver aspectj-weaving="autodetect"/>

但它在 JBoss 中不起作用，这是我需要部署最终版本的地方。其他解决方案？

在 Jboss 中，我需要在 xml（Service 和 Dao）中创建这两个东西，保持事务性注释。但是如果使用@Repository 或@Service 创建它们（dao 和服务），我将无法工作。

解决方案，我添加到 mvc-dispatcher-servlet.xml, mvc:interceptors 配置以打开与 org.springframework.orm.hibernate4.support.OpenSessionInViewInterceptor 的会话。只需要在属性中定义sessionFactory即可。
