我有一个服务需要会话来创建SQL查询然后执行它。就这些。我在顶级方法上有一个@Transactional
,但最终仍然会发生这种情况:
org.hibernate.HibernateException: No Hibernate Session bound to thread, and configuration does not allow creation of non-transactional one here

DaoRunner类是由Spring自动连接的,包含会话工厂。这是createSQLQuery方法:
public Query createSQLQuery(final String sql) {
return getCurrentSession().createSQLQuery(sql);
}
这是getCurrentSession()方法:
public Session getCurrentSession() throws HibernateException {
if (null == sessionFactory) {
throw new HibernateException(
"SessionFactory in DaoRunner is not wired.");
}
return sessionFactory.getCurrentSession();
}
我的顶级方法是:
@Transactional
public Result run() {
try {
String inputData = input.getInputData();
Result result = aClass.doSomething(inputData);
return result;
} catch (Exception e) {
String msg = ERROR_PREFIX + e;
StringWriter sw = new StringWriter();
e.printStackTrace(new PrintWriter(sw));
String stackTrace = sw.toString();
log.error(stackTrace);
throw new PermanentException(msg);
}
}
这是sessionFactory bean:
<bean id="AbstractSessionFactory"
class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean"
abstract="true">
<property name="packagesToScan">
<list>
<value>apackage</value>
</list>
</property>
<property name="exposeTransactionAwareSessionFactory">
<value>true</value>
</property>
</bean>
<bean id="sessionFactory"

<prop key="hibernate.c3p0.max_statements">50</prop>
<prop key="hibernate.connection.oracle.jdbc.ReadTimeout">60000</prop>
</props>
</property>
</bean>
<tx:annotation-driven transaction-manager="txManager" proxy-target-class="true" />
<bean id="txManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager">
<property name="sessionFactory" ref="sessionFactory" />
</bean>
请注意,我没有写过大部分内容。我添加了我的顶级方法和createSQLQuery()方法。

必须在IOC容器中注册的bean上调用用run
注释的@Transactional
方法。
要使此类成为bean,您可以在XML配置中注册它,或者只需在XML配置中使用@Component
注释和设置组件扫描来注释该类。然后从容器中注入bean并调用run
方法。
简单地说,需要从IOC容器中注入的bean调用run
方法。

您需要在spring配置中设置事务管理器,如下所示:
<!-- Enable Annotations for Transaction Management -->
<tx:annotation-driven transaction-manager="transactionManager" />
<!-- Creating TransactionManager, change class based on your requirement. -->
<bean id="transactionManager"
class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
<property name="dataSource" ref="dataSource" />
</bean>
