自定义 SPA 页面模型错误 - 无法解析为类型

Question

我正在使用 AEM 6.5.11，需要扩展 SPA 页面模型并形成特定于项目的页面模型，并向其添加更多属性，例如与分析相关的属性（我将从该模型的 OSGi Config 中获取这些属性）。无论我使用可编辑模板设计属性还是使用 OSGi 配置，我意识到我需要一个模型来为我提供有效负载语言、路径、分析 URL、页面 1 级别等。所以我想实现这个自定义模型来控制我需要在页面上渲染的内容。

我们正在使用 Angular SPA，它位于 spa 页面组件的 customheaderlibs.html 下。

<sly data-sly-use.mypage="com.sample.core.models.BasePageModel" />
${mypage.analyticsUrl}

请注意 - 此标头 html 中的原始页面包含效果很好 -

<meta
    property="cq:pagemodel_root_url"
    content="${page.hierarchyRootJsonExportUrl}"
    data-sly-use.page="com.adobe.aem.spa.project.core.models.Page"/>

我通过扩展 com.adobe.aem.spa.project.core.internal.impl.PageImpl 并实现 Page 创建了我的页面模型。 WCM 核心组件、spa.project.core 1.3.10 和 uber-jar 6.5.11 都作为我的核心 pom.xml 的依赖项。

由于未解析的导入包，该捆绑包现在看起来处于已安装状态 - com.adobe.aem.spa.project.core.internal.impl -- 无法解析 如果我不扩展 PageImpl 并仅实现 AEM SPA 页面接口，则该捆绑包处于活动状态，但我的自定义页面模型无法解析并且页面无法加载。我还尝试删除 core/pom.xml 中我提到的导入包中 com.adobe.aem.spa.project.core.internal.impl paackage 的内容 - !com.adobe.aem.spa.project。 core.internal.impl Sample.core 包变得活跃，但这看起来不是真正的解决方案。页面未加载，我的自定义模型在运行时仍然无法工作。

Cannot get DefaultSlingScript: Compilation errors in org/apache/sling/scripting/sightly/apps/sample/components/page/customheaderlibs__002e__html.java: Line 61, column 2865 : com.sample.aem.core.models.BasePageModel cannot be resolved to a type

这就是我声明自定义 SPA 页面模型类的方式

import com.adobe.aem.spa.project.core.internal.impl.PageImpl;
import com.adobe.aem.spa.project.core.models.Page;

@Model(
        adaptables = {SlingHttpServletRequest.class, Resource.class},
        adapters = {Page.class, ContainerExporter.class},
        resourceType = BasePageModel.RESOURCE_TYPE,
        defaultInjectionStrategy = DefaultInjectionStrategy.OPTIONAL
)
@Exporter(
        name = ExporterConstants.SLING_MODEL_EXPORTER_NAME,
        extensions = ExporterConstants.SLING_MODEL_EXTENSION
)
public class BasePageModel extends PageImpl implements Page {
  
    protected static final String RESOURCE_TYPE = "sample/components/page";
  
    @Self
    private SlingHttpServletRequest request;

    @ScriptVariable
    @JsonIgnore
    private Resource resource;
    
    @ScriptVariable
    @JsonIgnore
    protected ResourceResolver resolver;

    @ScriptVariable
    protected com.day.cq.wcm.api.Page currentPage;

    @ScriptVariable
    protected Style currentStyle;
    
    private String analyticsUrl = "CUSTOM ANALYTICS URL";
    
    @Nullable
    public String getAnalyticsUrl() {
        return analyticsUrl;
    }
}

堆栈跟踪如下 -

我可以在我的案例中找到这个问题 - 想把它写下来分享。
我需要在 core/pom.xml 上导出模型。
