问题 I have the following definitions for the Animal and Dog types.

How to enable hibernate query cache on a session level only?

问题 What if I have a query that gets called multiple times in a single thread, and I just want to cache that query (and its result) for that thread (or for that session since I'm using one session per thread), how can I do that ? Note: My 2nd level cache is turned on but it's used mostly for session.get(...). But I do not want to use it for my query cache because I only need it to live for the duration of my thread ( / session ). Thanks 回答1: The bottom line here is: you can either manually cache

Related to this question Premise: These are my assumptions, based on my reading, experience and understanding, they may be wrong, if they are, please comment and I'll edit the question. Query cache is good mostly along with 2nd level cache Query cache caches the identifiers results of queries + parameters Query cache is risky if the database was changed, and it wasn't reflected to the cache Question: I have an object that is not in the 2nd level cache. Due to some bad programming or other constraints, the code that loads the object is being called several time in the same hibernate session.

问题 So I have a Django project that doesn't use a database (the 'DATABASES' setting is commented out). I chose to use Django as there's a chance I will need the database functionality in the future.

Well, today I fired up the app and started the local server with no problems. I then tried to open the app
