得到“事務未成功啟動”

Question

每當我插入/更新到DB時，我都會得到此警告。 但是，我的數據仍然保存。 盡管如此，我還是想從我的日志文件中刪除它。

以下是我的日志文件：

[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)

這是我的服務暗示：

private HibernateSessionManager sessionManager;

public HibernateSessionManager getSessionManager() {
    return sessionManager;
}

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

@Inject
private SessionFactory sessionFactory;

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

public Session getHibernateSession() {
    if (getSessionManager() != null)
        return getSessionManager().getSession();
    else
        return sessionFactory.getCurrentSession();
}

@SuppressWarnings("rawtypes")
public Criteria createCriteria(Class clazz, Criterion... criterion) {
    Session session = getHibernateSession();

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

    Criteria crit = session.createCriteria(clazz);
    for (Criterion c : criterion)
        crit.add(c);

    return crit;    
}

@SuppressWarnings({ "unchecked", "rawtypes" })
public <T, ID extends Serializable> T get(ID id, boolean lock, Class clazz) {
    if (id == null)
        return null;

    T entity;
    Session session = getHibernateSession();

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

    if (lock)
        entity = (T) session.load(clazz, id);
    else
        entity = (T) session.get(clazz, id);

    return entity;
}

@SuppressWarnings("rawtypes")
public <T extends Serializable> List<T> findAll(Class clazz) {
    return findByCriteria(clazz);
}

@SuppressWarnings({ "rawtypes", "unchecked" })
public <T extends Serializable> List<T> findByCriteria(Class clazz, Criterion... criterion) {
    Session session = getHibernateSession();
    Criteria crit = session.createCriteria(clazz);
    for (Criterion c : criterion)
        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;
}

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

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

public <T extends Serializable> void createOrUpdate(T entity) {
    Transaction tx = getHibernateSession().beginTransaction();
    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);
}

我不知道這是否會影響我的應用程序性能。 來自Stack Overflow的另一個問題相同的答案並沒有幫助解決我的問題。 我想知道我的情況是否不同。

您是否嘗試過使用@CommitAfter注釋，而不是在代碼中顯式啟動和提交轉換？
