Spring和Hibernate 4：如果没有活动事务，get就无效

标签： spring hibernate spring-transactions spring-annotations

我使用Spring注释和hibernate来创建DAO。我使用的是Spring 3.2.5和hibernate 4.3.3。出于某种原因，我一直得到这个例外：

org.hibernate.HibernateException：如果没有活动事务，则get无效

以下是我的春季应用背景的相关部分：

<tx:annotation-driven transaction-manager="transactionManager" />

        <!-- Pick up the HibernateHouseDAO spring bean -->
        <context:component-scan base-package="jinvestor.jhouse.download" />

        <bean id="sessionFactory"
            class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">
            <property name="dataSource" ref="dataSource" />
            <property name="annotatedClasses">
                <list>
                    <value>jinvestor.jhouse.core.HouseEntity</value>
                </list>
            </property>
            <property name="hibernateProperties">
                <props>
                    <prop key="hibernate.dialect">org.hibernate.dialect.MySQLDialect</prop>
                    <prop key="hibernate.current_session_context_class">thread</prop>
<!--                    <prop key="hibernate.transaction.factory_class">org.hibernate.transaction.JDBCTransactionFactory</prop> -->
                </props>
            </property>
        </bean>

        <bean id="dataSource"
            class="org.springframework.jdbc.datasource.DriverManagerDataSource">
            <property name="driverClassName" value="${dataSource.driver}" />
            <property name="url" value="${dataSource.url}" />
            <property name="username" value="${dataSource.username}" />
            <property name="password" value="${dataSource.password}" />
        </bean>

        <bean id="transactionManager"
            class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
            <property name="dataSource" ref="dataSource" />
        </bean>

这是我的DAO：

@Repository("dao")
@Profile("mysql")
@Transactional
public class HibernateHouseDAO implements HouseDAO {

    private final SessionFactory sessionFactory;

    @Autowired
    public HibernateHouseDAO(SessionFactory sessionFactory) {
        this.sessionFactory = sessionFactory;
    }

    @Override
    public House load(long id) {

        // this throws a nosuch method error for openSession.
//      Session session = SessionFactoryUtils.getSession(sessionFactory, false);

        // this throws an error on the lack of a transaction.
        Session session = sessionFactory.getCurrentSession();
        HouseEntity entity = (HouseEntity) session.get(HouseEntity.class, id);
        return House.fromEntity(entity);
    }

    @Override
    public void save(House house) {
        sessionFactory.getCurrentSession().save(new HouseEntity(house));
    }

BTW @Transactional是spring，而不是javax.transaction。这是我的单元测试：

// MT stands for manual test
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations={"classpath:/applicationContext.xml"})
@ActiveProfiles(profiles={"test","mysql"})
public class HibernateHouseDAOMT extends HouseDAOTest {

    @Autowired
    private HouseDAO dao;

    @Override
    public HouseDAO getDao() {
        return dao;
    }
}

以下是我的SQL架构，以防您需要了解它：

create table homes (zpid BIGINT PRIMARY KEY NOT NULL, address VARCHAR(200) NOT NULL,squareFeet INT UNSIGNED,soldPrice INT UNSIGNED, latitude INT,longitude INT,lastSoldDate DATE, yearBuilt YEAR,acres FLOAT UNSIGNED,beds TINYINT UNSIGNED,baths TINYINT UNSIGNED, INDEX (address)) ENGINE = 'INNODB';

此外，我的所有代码都在github上，以防你想看到我没有在这里复制的内容。这是github上的项目根目录：

请帮助我开始工作。

=================== 更新：

切换到Hibernate事务管理器：

    <bean id="transactionManager"
        class="org.springframework.orm.hibernate4.HibernateTransactionManager">
        <property name="sessionFactory" ref="sessionFactory" />
    </bean>

以下是例外：

基于此，也许我错过了我的pom中的依赖，或者有一个坏的依赖。我会试着找出......

我使用的是mysql-connector-java版本5.1.29，也许这是不兼容的？

您正在使用Spring 3.2.5，它与您正在使用的最新Hibernate 4.3.3版本不兼容。 Hibernate 4.3确实决定更改ConnectionProvider返回的SessionFactoryImplementor.getConnectionProvider()的包。使用最新的Spring版本，或使用Hibernate 4.2，它应该运行得更好。
