Hi,
1) I have got a Class User who accessed by Hibernate.

2) I have now a method getUser() who gets a specific user from DB (with hibernate).

3) I have a jsp file which shows the users settings. I am accessing these settings via getUser().getXXX. The User has round about 20 settings.

Do I access the Database 20 times or does HIbernate caches my specific user and I have not worry about to use the getUser() method to fill the setting.jsp?

Thnx
Alex

I you use a session-in-view pattern and configure everything correctly, there will be 1 query executed on the db.
After that, your user object is in the 1st level cache.
That cache is available for 1 transaction (more or less).

For more info, see: http://hibernate.org/42.html

Another fast and secure way to check how many database queries are sent to your db: Just have a look to your db logs or db monitor. Then you can retrace what happened exactly.

Hi

set show_sql=true to view all hibernate queries.
