FUSE hibernate application throws No Session found for current thread exception

123 views Asked by At

I'm working on simple demonstration of Hibernate on FUSE server and I found this sample code example in this github location. I'm try to run this code in FUSE 6.3 with Hibernate 4 integration I was able to install all the required dependencies but when I try to perform database operation I getting following error.

org.hibernate.HibernateException: No Session found for current thread

This is my StudentImpl.java file content.

    public class StudentDaoImpl implements StudentDao{

    private static final transient Log LOG = LogFactory.getLog(StudentDaoImpl.class);

        /** The session factory. */

            throws HibernateException
        {

            // Prepare query
            q = this.sessionFactory.getCurrentSession().createQuery( findStudent );

            // Retrieve the Incidents from database
            List<Student> list = q.list();

        }


        /*

            this.sessionFactory.getCurrentSession().saveOrUpdate( Student );
        }


    }

According to the exception following is the line it throw the exception

return (Student) this.sessionFactory.getCurrentSession().get( Student.class, id );

This is the project structure I have.

enter image description here

Does anyone experienced this kind of issue on FUSE hibernate integration. I was able to install project without any issue. But when ever I try to perform database operation I getting this error.

Please can some expert help me to resolve this issue.

You can resolve it by changing following things.

Add following to schemaLocation in beans tag according to following post.

http://www.springframework.org/schema/tx
http://www.springframework.org/schema/tx/spring-tx-2.5.xsd  

In there you should add following lines as well. Based on following post.

<tx:annotation-driven/>
<context:annotation-config />
<context:component-scan base-package="com.vcc.poc"></context:component-scan>

Then add @Transactional annotation for the methods for example

    @Transactional
    public Student getStudent(int id)

Changed beans annotation should be similar to below.

<beans xmlns="http://www.springframework.org/schema/beans"
