hibernate - 没有配置 CurrentSessionContext! : ThreadLocalSessionContext. 绑定(bind)( session )；没有正确绑定(bind)我的 session

Question

我正在使用 Hibernate 4.0.1.Final。

我在测试服务时无法绑定(bind) session 。我使用 ThreadLocalSessionContext.bind(session) 尝试绑定(bind) session ，以便 sessionFactory.getCurrentSession() 返回有效 session ，但它不起作用。

调用 sessionFactory.getCurrentSession() 会产生异常(如下)。在我的服务类(class)中，我有:

public class OrganizationServiceImpl extends AbstractTransactionService implements OrganizationService {

public void saveOrganization(final String eodbId,
                             final String parentEodbId,
                             final String name,
                             final String description,
                             final String organizationType,
                             final String url,
                             final String stateAbbrev) {
    Session session = null;
    try {
        session = startOperation();
        final State state = orgDao.findStateByAbbrev(stateAbbrev);

…

protected Session startOperation() throws HibernateException {
    final Session session = sessionFactory.openSession();
    ThreadLocalSessionContext.bind(session);
    tx = session.beginTransaction();
    return session;
}

这是调用此服务的 JUnit 测试......

@Before
public void setupOrgServiceTest() { 
    Configuration config = new Configuration()
        .setProperty("hibernate.dialect", "org.hibernate.dialect.HSQLDialect")
        .setProperty("hibernate.connection.driver_class", "org.hsqldb.jdbcDriver")
        .setProperty("hibernate.connection.url", "jdbc:hsqldb:mem:lyceaTestDb")
        .setProperty("hibernate.connection.username", "sa")
        .setProperty("hibernate.connection.password", "")
        .setProperty("hibernate.connection.pool_size", "1")
        .setProperty("hibernate.connection.autocommit", "true")
        .setProperty("hibernate.cache.provider_class", "org.hibernate.cache.HashtableCacheProvider")
        .setProperty("hibernate.hbm2ddl.auto", "create-drop")
        .setProperty("hibernate.show_sql", "true")
        .addAnnotatedClass(Organization.class)
        .addAnnotatedClass(State.class); 
    final ServiceRegistry serviceRegistry = new ServiceRegistryBuilder().applySettings(config.getProperties()).buildServiceRegistry();
    sessionFactory = config.buildSessionFactory(serviceRegistry);
    orgService = new OrganizationServiceImpl(sessionFactory);
}   // setupOrgSErviceTest

@Test
public void testSaveOrg() { 
    orgService.saveOrganization(testProps.getProperty("test.school.eodbId"),
                                testProps.getProperty("test.school.parent.eodbId"),
                                testProps.getProperty("test.school.name"), 
                                testProps.getProperty("test.school.description"), 
                                testProps.getProperty("test.school.org.type"), 
                                testProps.getProperty("test.school.url"), 
                                testProps.getProperty("test.school.state"));
}   // testSaveOrg

我在调用 sessionFactory.getCurrentSession() 时得到的异常是

您没有指定告诉 SessionFactory 使用 ThreadLocalSessionContext 的 Hibernate 属性。

setProperty("hibernate.current_session_context_class", "thread")

这意味着当您的 SessionFactory 被构建时，Hibernate 不会设置 currentSessionContext。当您调用 getCurrentSession() 时，Hibernate 无法从中检索当前 session 。

其他选项是 jta 和 managed。
