重新部署EJB後的javax.ejb.NoSuchEJBException

2011-01-12 58 views

使用Glassfish 3.0.1 ...如果我有一個Web應用程序遠程訪問另一個應用程序中的EJB，並且包含該EJB的遠程應用程序被重新部署，我得到一個javax.ejb.NoSuchEJBException （請參閱下面的堆棧跟蹤）。重新部署EJB後的javax.ejb.NoSuchEJBException

不應該工作嗎？我可以看到使用完全相同的JNDI名稱成功部署了有問題的EJB。

有沒有其他方法可以解決這個問題，而不是重新啓動Web應用程序？應當指出的是，在這個特殊的例子，該堆棧跟蹤是，我訪問與CDI注入豆一個servlet：

public class StatusServlet extends HttpServlet { 

    @Inject 
    private StatusService statusService; 

    @Override 
    public void doGet(final HttpServletRequest req, final HttpServletResponse res) throws IOException { 
     res.getWriter().write(statusService.getStatus()); 
    } 
}

注射用下面的生產商做可以得到正確的EJB：

public class StatusServiceProducer extends AbstractServiceProducer { 

@EJB(name = "StatusService") 
private StatusService service; 

@Produces 
public StatusService getService(final InjectionPoint ip) { 
    return service; 
} 

}

生產者被用來使服務更容易包裝在代理中，並且更容易改變查找EJB的方式。

的StatusService接口和實現如下：

@Stateless(name = "StatusService") 
public class StatusServiceImpl implements StatusService { 
    private static final String OK = "OK"; 

    public String getStatus() { 
     // Some code 
     return OK; 
    } 
} 
public interface StatusService { 
String getStatus(); 
}

編輯：提供我自己可能solution。有更好的嗎？

StatusService的外觀如何？我相信CDI爲EJB創建代理，但在重新部署後，此代理不再工作。 AFAIK CDI不適合遙控。你不能只用@EJB而不是@Inject注入EJB？ – amorfis 2011-01-12 22:49:07

@amorfis：是的，你是對的......我們使用EJB，請參閱我添加的生產者代碼。關於最初的問題，我相信這是在這裏解釋：http://www.java.net/forum/topic/glassfish/glassfish/redeploy-tree-0另請參見：http://www.java.net/論壇/主題/ glassfish/glassfish/javaxejbnosuchejbexception-after-redeplo – Vetle 2011-01-13 08:21:29

從上Glassfish的論壇上discussion：

注入參考更新，只有當一個新的實例，它被注入由創建EJB容器。因此，如果您始終查找它，則會獲得帶有更新引用的實例，但是如果代碼保留在原始實例上，或者彙集了該實例，則注入的引用將保持陳舊。

所以根本問題就是對EJB的引用是陳舊。我已經發現了兩個解決問題的對策：

  1. 查一查每個請求的EJB（不使用CDI）
  2. 包裹的EJB在查找的EJB如果引用是陳舊的代理

第二種解決方案仍然可以使用CDI。您需要一個生產商和InvocationHandler。下面的代碼是我在我的項目中使用的代碼的簡化版本，它可能無法正確編譯，但它會顯示用於完成此項工作的想法和概念。因人而異。

首先，在使用EJB的代碼，你可以使用@Inject，如下：

public class Foo { 
    @Inject 
    MyEjb obj; 
}

其次，你需要一個製片人，僅僅返回EJB的包裝版本：

public class MyEjbProducer { 
    @EJB(name = "MyEjb") 
    private MyEjb obj; 

    @Produces 
    public MyEjb getEjb(final InjectionPoint ip) { 
     InvocationHandler handler = new MyInvocationHandler(obj, MyEjb.class); 
     return (MyEjb)Proxy.newProxyInstance(obj.getClass().getClassLoader(), obj.getClass().getInterfaces(), handler); 
    } 
}

三，調用處理程序需要測試NoSuchEjbException，再次查找該bean：

public class MyInvocationHandler implements InvocationHandler { 
    private MyEjb obj; 
    private Class lookupClass; 

    public MyInvocationHandler(MyEjb obj, Class lookupClass) { 
     this.obj = obj; 
     this.lookupClass = lookupClass; 
    } 

    public Object invoke (...) { 
     try { 
      return method.invoke(impl, args); 
     } catch (final InvocationTargetException e) { 
      if (e.getTargetException() instanceof NoSuchEJBException) { 
       // 1. look up EJB again 
       // 2. try calling invoke again      
      } 
     } 
    } 
}

此代碼並不完整。一些代碼，例如查找EJB並再次調用方法已被省略。

這樣做會起作用。另一種方法是做類似的事情，但在EJB中添加一個單獨的方法來檢查陳舊性，而不是使用用戶試圖調用的方法。

您認爲如何？有更好的解決方案嗎？

唯一的解決方案是不使用@EJB注入作爲servlet中的一個字段（它在類加載時被注入，所以應用程序啓動或首次使用servlet，而是爲每個請求請求一個新實例。 可悲的是，這並不意味着你不能使用@EJB注入註解，將有利用來處理EJB以舊的方式JNDI查找等
