java - GlassFish 2.1 上的 EJB 依赖项未正确连接(注入(inject))

Question

出于某种原因，我应该使用旧的 EJB 容器 GlassFish 2.1.1。 (经过 Java EE 5 和 EJB 3.0 认证)。项目结构如下:

MDB:

@MessageDriven(
   mappedName = "jms/Queue",
   activationConfig = {
      @ActivationConfigProperty(propertyName = "destinationType", 
                                propertyValue = "javax.jms.Queue")    
})
public class TriggerMBean implements MessageListener {
     @EJB
     private TriggerProcessor triggerService; 

     public void onMessage(Message message) {
          //.......
          triggerService.process();
          //.......
     }
}

触发处理器:

@Stateless
public class TriggerProcessor {
    public void proceess() {
        //....
    }
}

我尚未创建部署描述符。据我了解，如果我使用注释和 EJB 版本从 3.0 开始，则没有必要

部署时出现以下异常:

我尝试使用 @EJB(beanName="TriggerProcessor") 和 public class TriggerProcessor {.. 注释 private TriggerProcessor triggerService; @Stateless(name="TriggerProcessor") 但没有帮助。

实际上，这在最新的 Glassfish 3.1 上完美运行。但正如我所说，我应该使用 GF 2.1.1。

感谢任何帮助!

它无法工作，因为 GlassFish 2 不支持 EJB 3.1。 TriggerProcessor 仅提供无接口(interface) View ，因为它不实现任何接口(interface)。您必须为 TriggerProcessor 提供一个接口(interface)，以便与 EJB 3.0 兼容。

仅 EJB 3.1 支持无接口(interface) View 。请参阅http://docs.oracle.com/cd/E19776-01/820-4496/beahm/index.html以及 JSR 318 规范的 1.2 EJB 3.1 中的新增功能 章节。
