org.hibernate.HibernateException: No Session found for current thread
Solution 1
getCurrentSession()
only makes sense inside a scope of transaction.
You need to declare an appropriate transaction manager, demarcate boundaries of transaction and perform data access inside it. For example, as follows:
<bean id = "transactionManager" class = "org.springframework.orm.hibernate4.HibernateTransactionManager">
<property name = "sessionFactory" ref = "sessionFactory" />
</bean>
.
PlatformTransactionManager ptm = context.getBean(PlatformTransactionManager.class);
TransactionTemplate tx = new TransactionTemplate(ptm);
tx.execute(new TransactionCallbackWithoutResult() {
public void doInTransactionWithoutResult(TransactionStatus status) {
// Perform data access here
}
});

I came across same problem and got solved as below Added @Transactional on daoImpl class
Added trnsaction manager in configuration file:
<tx:annotation-driven/>
<bean id="transactionManager"
class="org.springframework.orm.hibernate4.HibernateTransactionManager">
<property name="sessionFactory" ref="sessionFactory"></property>
</bean>
Solution 3
I'll just add something that took me some time to debug : don't forget that a @Transactional annotation will only work on "public" methods.
I put some @Transactional on "protected" ones and got this error.
Hope it helps :)
http://docs.spring.io/spring/docs/3.1.0.M2/spring-framework-reference/html/transaction.html
Method visibility and @Transactional
When using proxies, you should apply the @Transactional annotation only to methods with public visibility. If you do annotate protected, private or package-visible methods with the @Transactional annotation, no error is raised, but the annotated method does not exhibit the configured transactional settings. Consider the use of AspectJ (see below) if you need to annotate non-public methods.

I'm getting the above exception with Spring3 and Hibernte4
The following is my bean xml file
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:context="http://www.springframework.org/schema/context" xmlns:tx="http://www.springframework.org/schema/tx" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.1.xsd"> <context:annotation-config/> <bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource"> <property name="driverClassName" value="com.mysql.jdbc.Driver"/> <property name="url" value="jdbc:mysql://localhost:3306/GHS"/> <property name="username" value="root"/> <property name="password" value="newpwd"/> </bean> <bean id="sessionFactory" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean"> <property name="dataSource" ref="dataSource"/> <property name="hibernateProperties"> <props> <prop key="dialect">org.hibernate.dialect.MySQL5Dialect</prop> </props> </property> <property name="packagesToScan"> <list> <value>com.example.ghs.model.timetable</value> </list> </property> </bean> <bean id="baseDAO" class="com.example.ghs.dao.BaseDAOImpl"/> </beans>
My BaseDAO class looks like this
public class BaseDAOImpl implements BaseDAO{ private SessionFactory sessionFactory; @Autowired public BaseDAOImpl(SessionFactory sessionFactory){ this.sessionFactory = sessionFactory; } @Override public Session getCurrentSession(){ return sessionFactory.getCurrentSession(); } }
The following code throws the exception in the title
public class Main { public static void main(String[] args){ ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext("dao-beans.xml"); BaseDAO bd = (BaseDAO) context.getBean("baseDAO"); bd.getCurrentSession(); } }
Does anyone have an idea about how to solve this problem?
