Question

每次插入/更新到DB时，我都会收到此警告。但是，我的数据仍然保存。尽管如此，我还是想从我的日志文件中删除它。

下面是我的日志文件：

[WARN] TapestryIOCModule.PerthreadManager Error invoking listener org.apache.tapestry5.internal.hibernate.HibernateSessionManagerImpl@41c045: Transaction not successfully started org.hibernate.TransactionException: Transaction not successfully started at org.hibernate.transaction.JDBCTransaction.rollback(JDBCTransaction.java:179) at org.apache.tapestry5.internal.hibernate.HibernateSessionManagerImpl.threadDidCleanup(HibernateSessionManagerImpl.java:65)

这是我的服务提示：

public HibernateSessionManager getSessionManager() {
    return sessionManager;
}

public void setSessionManager(HibernateSessionManager sessionManager) {
    this.sessionManager = sessionManager;
}

@Inject

public void setSessionFactory(SessionFactory sessionFactory) {
    this.sessionFactory = sessionFactory;
}

    if (getSessionManager() != null)
        return getSessionManager().getSession();
    else
        return sessionFactory.getCurrentSession();
}

@SuppressWarnings("rawtypes")

    Session session = getHibernateSession();

    if (!session.getTransaction().isActive())

    Criteria crit = session.createCriteria(clazz);

        crit.add(c);

    return crit.list();
}

public <T extends Serializable> T create(T entity) {
    Transaction tx = getHibernateSession().beginTransaction();
    getHibernateSession().saveOrUpdate(entity);
    tx.commit();
    return entity;
}

    getHibernateSession().saveOrUpdate(entity);
    tx.commit();
}

public <T extends Serializable> T merge(T entity) {
    Transaction tx = getHibernateSession().beginTransaction();
    getHibernateSession().merge(entity);
    tx.commit();
    return entity;
}

// USER

@Override
public User createOrUpdateUser(User user) {
    if (user.getId() == null || user.getId() == 0) {
        String encodePass = PasswordUtils.EncodePassword(user.getName(), user.getPassword());
        user.setPassword(encodePass);
    }

    if (user.getId() == null)
        return create(user);
    else
        return update(user);
}

@Override
public User getUserByID(Integer id) {
    return get(id, false, User.class);
}

我不知道这是否会影响我的应用程序性能。来自Stack Overflow的另一个问题相同的答案并没有帮助解决我的问题。我想知道我的情况是否不同。

您是否尝试过使用@CommitAfter注释，而不是在代码中显式启动和提交转换？

获取“事务未成功启动”
