Hi. I have a problem with cache of hibernate 4.0.1.Final.
I tried use session clear and evict but not working.
I want not to use cache.
I don't know how but when I don't use session close then the cache is clear.
Today I am doing this for do not use the cache.
This is my method:

Code:
   public List<MyClass> getByFilter(MyClass user){
      session = HibernateConnectionGoogleCloud.getInstanceGoogleCloud();
      List<MyClass> mList = new ArrayList<MyClass>();
      mList = null;
      
      try{
         List<MyClass> list = new ArrayList<MyClass>();

         Criteria criteria = session.createCriteria(MyClass.class);
         
         if(!user.getIdentificador().equals("")){
            criteria.add(Restrictions.eq("identificador", user.getIdentificador()));
         }
                  
         criteria.add(Restrictions.between("data", user.getBeginDate(), user.getEndDate()));
         list = criteria.list();
         
         if(list != null && list.size() > 0)
            mList = list;
         
      }catch (Exception e) {
         e.printStackTrace();
      }finally {
         //session.close();   
      }
      return mList;
   }


session close is commented = no cahce
session close is not commented = with cache

You have multiple options:

1. Either you use a StatelessSession
2. Or you use a read-only Session:

Code:
session.setReadOnly(true);


This way, nothing is going to store in the first-level cache.

As for the second-level cache, unless you explicitly configured it, it will not be activated.
