Spring中的EJB 3.0会话Bean等效于什么？

Question

它像使用@Transactional方法创建POJO一样简单吗？

Answer 1

Yes, spring beans are pojos. You have to declare it in applicationCotnext.xml or annotate it with @Service .

Answer 2

在Spring中，将其创建为普通bean，然后指定会话范围或@Scope批注。

Answer 3

Spring beans (ie properly declared) annotated with @Transactional are comparable to Local Session Beans. For Remote Session Beans, you would have to add some remoting to your Spring configuration (RMI, Web Services, Hessian, Burlap, HTTP invokers). But Spring remoting does not support out of the box security and transaction propagation (unlike EJBs).
