Question

我在Wildfly 15.0.0中遇到问题，它没有为同时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{ 
}

远程界面：

@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

并且当尝试按如下方式将这个EJB插入另一个类中时：

@Remote({BusinessUserManagerRemote.class})
@Local({BusinessUserManagerLocal.class})
@Stateless
public class BusinessUserManager
        implements BusinessUserManagerLocal, BusinessUserManagerRemote {

    @EJB
    private BlockingManagerLocal blockingManager;

}

我收到此异常：

相同的代码正在JBOSS EAP6上运行。为什么Wildfly无法识别本地接口BlockingManagerLocal？

Answer 1

我认为您应该将接口实现为纯 Java 接口，并在 bean 实现中添加注释 @LocalBean 而不是 @Local。

应避免使用远程 EJB。我建议改用 Rest 接口。

Wildfly不为实现2个接口的bean创建JNDI绑定
