【问题描述】：
Wildfly 15.0.0 存在一个问题，即它没有为实现本地和远程接口的 EJB 创建 JNDI。我的课程如下：
本地接口：
@Local
public interface BlockingManagerRemote{
}
远程接口：
@Remote
public interface BlockingManagerLocal{
}
实现：
@Remote({BlockingManagerRemote.class})
@Local({BlockingManagerLocal.class})
@Stateless
public class BlockingManager
implements BlockingManagerRemote, BlockingManagerLocal {
}
我首先收到以下消息：
2019-03-13 12:09:57,459 INFO [org.jboss.as.ejb3.deployment] (MSC service thread 1-3) WFLYEJB0111: No jndi bindings will be created for EJB BlockingManager since no views are exposed
当尝试将该 EJB 注入另一个类时，如下所示：
@Remote({BusinessUserManagerRemote.class})
@Local({BusinessUserManagerLocal.class})
@Stateless
public class BusinessUserManager
implements BusinessUserManagerLocal, BusinessUserManagerRemote {
@EJB
private BlockingManagerLocal blockingManager;
}
我得到了这个例外：

同样的代码在 JBOSS EAP6 上运行。为什么 Wildfly 无法识别本地接口BlockingManagerLocal？
【问题讨论】：
-
在您的示例中，您在 BlockingManagerRemote 类上有 @Local，这只是此处发布的错误还是您的代码中的错误？我假设您的接口实际上也列出了一些方法？
-
是的，@Local 注解也在界面上。两个接口都包含方法，但我在问题中省略了它们。
-
请出示您的application.xml
-
我的评论你把@Local 放在你的遥控器上，反之亦然？
