我一直在关注文档here
显然，为了让我的＆＃34;使用＆＃34;我的Sightly组件可以看到class，我需要做的就是在我的＆＃34;使用＆＃34;中使用完整的Class名称（即包括包）。言。
<div data-sly-use.listChildren="com.t4g.aem.impl.usebeans.ListChildrenUseBean"><!-- Markup --></div>
我已按照说明操作并构建并部署了我的捆绑包。我的编译类在那里（我破解了JAR以确定。）然而，Sightly引擎找不到我的类。我尝试过WCMUse和WCMUsePojo。我已经在Sightly标记中尝试了替代语法（我在这里和那里找到了变体）。似乎没有什么东西适用于捆绑的使用bean。
如果我将同一个类放入组件并更新包以匹配，一切正常。
我很想知道：
感谢您的帮助。
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.
完整的异常跟踪如下（它真的很长，抱歉）：

这是我找到的解决方案，感谢我在其他地方获得的一些帮助。
要避免此问题，您需要确保捆绑包的OSGi清单的import-package（即依赖项）和export-package（即您的＆＃34;使用＆＃34;类）反映您希望向Sightly脚本公开的类。这将使Felix能够了解它们并将它们注入到需要它们的任何地方。
以下是从我的测试代码配置（即myproject-bundle / pom.xml）中剪切的示例：
<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>
我忽略了这一点的原因是，这个步骤对于我用来创建捆绑的类（例如OSGi服务，如Servlet，Scheduler等）来说并不是必需的。在那些，我使用Felix SCR注释允许不同的插件获取类并自动将它们添加到清单中。 （我相信这是 org.apache.felix.maven-scr-plugin 。）
底线是，要使一个类在OSGi包外部可见，它需要在清单中注册。有时我们使用 org.apache.felix.scr.annotations ，有时我们需要明确告诉我们的Maven构建它们。
希望这个答案可以帮助遇到同样问题的人。一旦你知道什么是缺失的，那一切都是有道理的。
谢谢！
