@Transactional(propagation=Propagation.REQUIRED,readOnly=false)
public class StudentDaoImplHT implements StudentDao {
private HibernateTemplate ht;
public void setHt(HibernateTemplate ht) {
this.ht = ht;
}
@Transactional
@Override
public int save(Student st) {
int i=(Integer) ht.save(st);;
System.out.println(st.getId());
System.out.println(st.getAddress());
System.out.println(st.getEmail());
System.out.println(st.getName());
return i; }
@Override
public boolean update(Student st) {
ht.saveOrUpdate(st);
return true;
}
@Override
public boolean delete(Student st) {
//ht.delete(st);
return true;
}
@Override
public Student findByPK(int id ) {
Student std=(Student) ht.get(Student.class, id);
return std;
}
@Override
public List<Student> findByAllUsingHQL() {
List<Student> list=(List<Student>) ht.find("from Student");
return list;
}
@Override
public List<Student> findByAllUsingCriteria() {
DetachedCriteria dc=DetachedCriteria.forClass(Student.class);
//dc.setProjection(projection);
//ht.findByCriteria(criteria)
List<Student> list= (List<Student>) ht.findByCriteria(dc);
return null;
}
}

请确保您的hibernate.cfg.xml
中具有以下属性:
"hibernate.connection.autocommit" true"
property name="hibernate.connection.autocommit" true property
希望有帮助。
