org.hibernate.HibernateException：当前没有会话绑定到执行上下文

标签： hibernate session spring-security dao sessionfactory

我正在尝试将Spring Security与Hibernate集成。我是这两种技术的新手，所以我几乎肯定会在这里采取太多步骤，但我正处于我想从数据库中验证用户身份的地步。我认为这肯定是一个Spring Security问题的Hibernate问题，但我提到它给出一些上下文。以下是错误消息和代码。有谁能发现什么？

配置DAO和事务管理：

<bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
    <property name="configLocation">
        <value>classpath:hibernate.cfg.xml</value>
    </property>
</bean>

<bean id="transactionManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager">
    <property name="sessionFactory" ref="sessionFactory" />
</bean>

<bean id="hibernateUserDAO" class="com.vicinity.dao.hibernate.HibernateUserDAO">
    <property name="sessionFactory" ref="sessionFactory" />
</bean>

<bean id="userManagerTarget" class="com.vicinity.service.PersistentUserManager">
    <property name="userDAO" ref="hibernateUserDAO" />
</bean> 

<bean id="userManager" class="org.springframework.transaction.interceptor.TransactionProxyFactoryBean">
    <property name="transactionManager">
        <ref local="transactionManager" />
    </property>
    <property name="target">
        <ref local="userManagerTarget" />
    </property>
    <property name="transactionAttributes">
        <props>
            <prop key="loadUserByUsername">PROPAGATION_REQUIRED</prop>
        </props>
    </property>
</bean>

这是实现UserDetailsService的类，用于对用户进行身份验证。这会调用DAO，请参阅第userDAO.getUserByLogin(login);行：

@Service("userManager")
@Transactional(propagation = Propagation.REQUIRED, readOnly = true)
public class PersistentUserManager implements UserManager, UserDetailsService {

        @Override
        public UserDetails loadUserByUsername(String login) throws UsernameNotFoundException, DataAccessException {
            User user = userDAO.getUserByLogin(login);

            if (null == user) {
                logger.error("User with login: " + login + " not found in database");
                throw new UsernameNotFoundException("user not found in database");
            }

            org.springframework.security.core.userdetails.User springUser;

            springUser = new org.springframework.security.core.userdetails.User(user.getLogin(), user.getPassword(), true,
                    true, true, true, new ArrayList<GrantedAuthority>());

            return springUser;
        }
    }

这是从数据库中读取的DAO。请注意，我正在尝试利用'GenericDAO模式'：

@Repository("userDAO")
public class HibernateUserDAO extends GenericHibernateDAO<User, Long> implements UserDAO {

    public HibernateUserDAO() {
        super(User.class);
    }

    @Override
    public void createUser(User user) {
        super.makePersistent(user);
    }

    public User getUserByLogin(String login) {
        if (null == login) {
            throw new IllegalArgumentException("You must provide a username if you want to get the user.");
        }

        List<User> users = findByCriteria(Restrictions.eq("login", login));

        // TODO, might need to check here if there are more than one user with the same username
        if(users == null || users.size() == 0) {
            return null;
        } else {
            return users.get(0);
        }
    }
}

这是发生错误的类，行Criteria crit = getSessionFactory().getCurrentSession().createCriteria(getPersistentClass());：

public abstract class GenericHibernateDAO<T, ID extends Serializable> implements GenericDAO<T, ID> {

    private Class<T> persistentClass;

    private SessionFactory sessionFactory;

    @SuppressWarnings("unchecked")
    protected List<T> findByCriteria(Criterion... criterion) {
        Criteria crit = getSessionFactory().getCurrentSession().createCriteria(getPersistentClass());
        for (Criterion c : criterion) {
            crit.add(c);
        }
        return crit.list();
    }
}

我的hibernate配置（hibernate.cfg.xml）中有以下内容可能是相关的：

<property name="current_session_context_class">org.hibernate.context.ManagedSessionContext</property>

4 个答案:

答案 0 :(得分：2)

尝试使用此属性名称。

<property name="hibernate.current_session_context_class">
       org.hibernate.context.ManagedSessionContext</property>

但是，最好配置spring来负责会话和事务管理。您可以查看this。

答案 1 :(得分：0)

您是否配置了交易管理？ 

org.springframework.orm.hibernate3.HibernateTransactionManager

和

org.springframework.transaction.interceptor.TransactionProxyFactoryBean

答案 2 :(得分：0)

我认为问题是由

引起的 
springUser = new org.springframework.security.core.userdetails.User(user.getLogin(), user.getPassword(), true, true, true, true, new ArrayList<GrantedAuthority>());

Spring在DAO中使用了一个模板模式，所以当你执行getUserByLogin会话是由Spring创建的，当你退出这个方法时，会话就会关闭。所以当你再次user.getLogin()时没有附加会话，你得到错误。

尝试使用OpenSessionInViewFilter ....您可能需要在谷歌中搜索它（因为我自己也没有使用它，因此无法在此处显示代码）

另外你可以再做一件事，如果你从DAO本身返回springUser（即在getUserByLogin本身，那么它将使用相同的会话对象，它应该工作）

答案 3 :(得分：0)

我最近遇到了同样的错误，并且试图找出问题所在，试图找到问题。

就我而言，我使用的是OpenSessionInViewFilter文件中配置的web.xml，以及那里的Spring Security配置。

由于Spring Security和OpenSessionInViewFilter都是过滤器，因此应用它们的顺序取决于它们在web.xml文件中的显示顺序。

就我而言，我最初在Spring Security过滤器下面有OpenSessionInViewFilter。一旦我交换了他们的位置（即将OpenSessionInViewFilter置于Spring Security之上），一切正常！
