Spring + Hibernate session management across multiple threads

耗尽温柔 提交于 2019-12-03 02:11:17
I am building a system, where each request from a client side spawns multiple threads on server side. Each thread then is using one or more DAOs (some DAOs can be used by more than one thread at the time). All DAOs are injected ( @Autowired ) to my thread classes by Spring. Each DAO receives SessionFactory injected as well. What would be proper way of managing Hibernate sessions across these multiple DAOs so I would not run into problems because of multithreaded environment (e.g. few DAOs from different threads are trying to use the same session at the same time)? Would be enough that I

SessionMap vs Map which is better for Session?

问题 Is there any advantages of using SessionMap over Map for a session in web application ? 1 advantage I found was you can invalidate a SessionMap but not Map . 回答1: The SessionMap is specifically designed for the purposes if you want to have access to the servlet session attributes. So, the user is able to keep a synchronized collection of objects in session and use it instead of HttpSession directly. This object is automatically injected by the servletConfig interceptor which is a part of the

Restore Emacs Session/Desktop

耗尽温柔 提交于 2019-11-30 05:15:07
I've been searching for how to restore an emacs session, with no luck. I'm looking to restore all previously open buffers, some of which might contain erc, shells, directory listings, files, etc. Every time I open emacs, I spend a considerable amount of time arranging my buffers; splitting them into rows and columns, opening a shell, arranging irc channels. It takes a while to get onto work. I've tried adding the following to my init.el (desktop-save-mode 1) And then using M-x desktop-save . This only seems to restore files that are open, not shells or anything else running within buffers. I

How to find out what open sessions my servlet based application is handling at any given moment

蹲街弑〆低调 提交于 2019-11-29 14:32:16
I need to write a servlet that, when called, gets information about a list of the currently opened sessions. Is there a way to do this? Implement HttpSessionListener , give it a static Set<HttpSession> property, add the session to it during sessionCreated() method, remove the session from it during sessionDestroyed() method, register the listener as <listener> in web.xml . Now you've a class which has all open sessions in the current JBoss instance collected. Here's a basic example: public HttpSessionCollector implements HttpSessionListener { private static final Set<HttpSession> sessions =

What is session management in Java?

怎甘沉沦 提交于 2019-11-28 17:16:30
问题 I have faced this question in my Interview as well. I do have many confusion with Session Scope & it management in java. In web.xml we do have the entry : <session-config> <session-timeout> 30 </session-timeout> </session-config> What does it indicate actually ? Is it scope of whole project ? Another point confusing me is how can we separate the session scope of multiple request in the same project? Means if I am logging in from a PC & at the same time I am logging in from another PC, does it
