StatelessSession being cast to Session in AbstractEntityPersister (Hibernate)

问题 I'm trying to do a simple save on a StatelessSession. Can someone spot what I'm doing wrong to end up in the Hibernate method that tries to do an invalid cast of StatelessSession to Session. I would appreciate any feedback. My example code: StatelessSession statelessSession = getSessionFactory().openStatelessSession(); Transaction tx = statelessSession.beginTransaction(); Object ret = null; try { ret = statelessSession.insert(obj); tx.commit(); statelessSession.close(); } catch (Throwable t)

Duplicate session creation & duplicate threads in AuthenticationProvider? Why?

阅读更多关于 Duplicate session creation & duplicate threads in AuthenticationProvider? Why?

问题 So I have some Spring Boot Security code, and for some reason although my STATELESS angular app sends a single GET request. The Spring Security seems to get two requests and start processing them in the same milliseconds on two threads (then I end up getting a unique user constraint as it tries to add same user twice to the DB). Is there something wrong with my spring security configuration where double-requests are happening? Spring Security should basically check ALL requests coming from

Initialize associated entity or collection fails with Stateless Session in NHibernate

问题 I'm trying to make an association with an entity from 3rd party dll. For some reasons, I have to use StatelessSession . With StatefullSession it works but not with Stateless. The idea is to allow 3rd party to add a table and have its data fetched when I query the main table. I have three projects: my main project, model project with the IExtender interface, and 3rd party project with Extender class (not referenced by the main project). My data schema: Table Data Id INT identity, more fields..

Lazy lookup of a dictionary value using a stateless session

问题 In my app, I set up a ternary dictionary mapping so that for a given user, I can retrieve "settings" for each instance of an object that belongs to the user. That is, I have something like: public class User { public virtual IDictionary<Baz, BazSettings> BazSettings { get; set; } //... So whenever I have a Baz object, I can lookup the current user's baz settings via currentUser.BazSettings[baz] . I would like to be able to use a stateless session to do this, but I get a

NodeJS - Framework for stateless sessions?

阅读更多关于 NodeJS - Framework for stateless sessions?

问题 Is there a framework to support fully client-managed sessions? In other words, instead of storing just the signed pid in the cookie (as Express does), store all context... so that you can manage state across clusters without the requirement to persist. 回答1: There is express middleware which supports this: https://github.com/expressjs/cookie-session cookieSession() Provides cookie-based sessions, and populates req.session. This middleware takes the following options: name - cookie name

Inserts of stateless session of NHibernate are slow

问题 It's been a couple of days that I'm working on improving NHibernate Insert performance. I'd read in many posts (such as this one) that stateless session can insert like 1000~2000 records per second.... However the best time that it could insert 1243 records is more than 9 seconds for me : var sessionFactory = new NHibernateConfiguration().CreateSessionFactory(); using (IStatelessSession statelessSession = sessionFactory.OpenStatelessSession()) { statelessSession.SetBatchSize(adjustmentValues
