在我的REST Web服务的服务层中使用@EJB或@Inject注入EJB？

[英]Injecting EJB with @EJB or @Inject in the service layer for my REST web service?

I have created some EJB's, they are annotated with @Stateless . 我创建了一些EJB，并用@Stateless进行了注释。 To use these EJB's in the other EJB's I am currently using the @EJB annotation. 为了在其他EJB中使用这些EJB，我目前正在使用@EJB注释。 I have created another layer (over the service layer) for my REST web service (I am using JAX-RS) and I wonder if I should use @EJB or @Inject . 我为我的REST Web服务创建了另一层（在服务层之上）（我正在使用JAX-RS），我想知道应该使用@EJB还是@Inject 。 I know these two are different things - and they probably live in different containers? 我知道这两件事是不同的-它们可能生活在不同的容器中吗？ If I use @Inject do I get the same EJB that I would have gotten with @EJB . 如果使用@Inject ，我将得到与@EJB相同的EJB。 Or do I get an EJB from the CDI container? 还是从CDI容器中获取EJB？

I also guess that by using @Inject I don't get all the EJB features that I would have gotten from @EJB ? 我还猜想，使用@Inject并不能获得@EJB提供的所有EJB功能？

@Inject supports the injection of EJBs. @Inject支持EJB的注入。 There is no functional difference, CDI is doing a lookup to find the object using the standard JNDI locations. 没有功能上的差异，CDI正在使用标准JNDI位置进行查找以找到对象。 The @EJB annotation has some additional capabilities, mostly around remoting or non standard JNDI locations that wouldn't be supported OOTB by @Inject @EJB批注具有一些附加功能，主要围绕@Inject OOTB不支持的远程处理或非标准JNDI位置
