悅目組件無法找到捆綁WCMUse（POJO）

顯然，爲了有我「用」類可見我悅目組件，所有我需要做的是使用在我的「使用」聲明中提供完整的類名（即包括包）。

<div data-sly-use.listChildren="com.t4g.aem.impl.usebeans.ListChildrenUseBean"><!-- Markup --></div>

我按照指示，建立和部署我的包。我編譯的課程在那裏（我打破了JAR來確定）。而且，Sightly引擎找不到我的課程。我試過WCMUse和WCMUsePojo。我已經嘗試了Sightly標記中的替代語法（我在這裏和那裏都找到了變體）。沒有什麼似乎適用於捆綁使用bean。

如果我將相同的類放入組件並更新包來匹配，一切正常。

我很想知道：

如果有人曾經得到實際上這個工作
如何得到它的工作

謝謝您的幫助。

我得到的例外是：

org.apache.sling.scripting.sightly.SightlyException: Identifier 
com.t4g.aem.impl.usebeans.ListChildrenUseBean cannot be correctly 
instantiated by the Use API 

[...] 

Caused by: org.apache.sling.scripting.sightly.SightlyException: Cannot 
find class com.t4g.aem.impl.usebeans.ListChildrenUseBean.

完整的異常跟蹤如下（這是很長的，不好意思）：

您的包是否在您的OSGI控制檯中處於活動狀態？你可以複製粘貼你的Java代碼（它的一部分）嗎？ – Bambara

我已經想通了（謝謝一些幫助）。關鍵是將你需要訪問的類添加到OSGi清單中的導出包中。這可以通過編輯bundle項目pom.xml並將它們添加到maven-bundle-plugin配置來完成。我會在下面發表一個答案。 – RIAGrande

通常，當您不能在AEM中實例化一個類時，它可能是您的包在OSGI控制檯中不處於「活動」狀態，如果您缺少依賴項或類不在包本身中，則可能發生這種情況。第二個選項非常少見，因爲大部分時間你將包含你在maven bundle插件中編寫的所有包，很高興你找到了答案。 – Bambara

這是我找到的解決方法，這要歸功於一些幫助我在別處收到。

爲避免此問題，您需要確保該包的OSGi清單的導入包（即依賴關係）和導出包（即您的「使用」類）反映了您希望暴露給Sightly腳本的類。這將允許菲利克斯知道它們並在需要的地方注入它們。

這是從我的測試代碼的配置剪斷的例子（即myproject的束/ pom.xml中）：

<plugin> 
    <groupId>org.apache.felix</groupId> 
    <artifactId>maven-bundle-plugin</artifactId> 
    <extensions>true</extensions> 
    <configuration> 
     <instructions> 
      <Bundle-SymbolicName>com.us.aem.sightly-stuff-bundle</Bundle-SymbolicName> 
      <Export-Package> 
       <!-- Let's export our primary package --> 
       com.us.aem.impl.usebeans 
       <!-- By default, don't export any other packages --> 
      </Export-Package> 
      <Import-Package> 

       <!-- JSR 250 && 330 --> 
       javax.annotation;version=0.0.0.1_007_JavaSE, 
       javax.inject, 

       <!-- JEE Servlet --> 
       javax.servlet, 
       javax.servlet.http, 

       <!-- Sling --> 
       org.apache.sling.api, 
       org.apache.sling.api.resource, 
       org.apache.sling.auth.core, 
       org.apache.sling.jcr.api, 
       com.day.cq.commons, 
       org.apache.sling.api.request, 
       com.adobe.cq.sightly, 
       com.day.cq.wcm.api, 
       org.slf4j 
      </Import-Package> 
     </instructions> 
    </configuration> 
</plugin>

爲什麼我忽略了這是，這一步是沒有必要的類的原因我習慣於創建捆綁包（例如，OSGi服務，例如Servlets，Schedulers等）。在這些應用中，我使用Felix SCR註釋，允許不同的插件獲取類並將其自動添加到清單中。（I相信這是org.apache.felix.maven-SCR-插件纔會這樣。）

的底線是一類是OSGi包外部可見，它需要在要註冊清單。有時我們使用org.apache.felix.scr.annotations，有時我們需要明確告訴我們的Maven構建它們。

希望這個答案可以幫助遇到同樣問題的人。一旦你知道缺少什麼，這一切都是有道理的。

謝謝！
