问题 I'm using Hibernate with Spring on Tomcat. I've been reading and re-reading the oft pointed to JBoss wiki page on the topic, and that has been helpful. But it leaves me with some questions. The idea of starting a transaction for every request troubles me. I guess I could limit the filter to certain controllers -- maybe put all my controllers that need a transaction under a pseudo "tx" path or something.
