Apache Sling脚本解析规则如何工作？

Question

我的tst内容名称在页面中

sling:resourceType = news-portal/pages/test

页面结构(下/apps):

测试了

sling:resourceSuperType = news-portal/pages/news-repo-main-page

在浏览器中我键入以下URL:

http://localhost:4502/cf#/content/tst.selector.pdf.html

在此请求后,我看到了内容 selector.jsp

但我希望看到内容,selector.pdf.jsp 因为根据我的意见它更适合.

1. 你能解释它是如何工作的吗？

2. 有可以显示内容的URL selector.pdf.jsp吗？

3. 内容的选择是否影响测试是 sling:resourceType 代替sling:resourceSuperType还是一起？(我尝试测试但看不到感情)

PS

我知道答案在这里:

但我理解上有问题

UPDATE

我注意到,如果我创建以下结构并发送请求

http://localhost:4502/cf#/content/tst.selector.pdf.html

我看到了内容 pdf.jsp

Answer 1

在Sling中有两件事:内容(存储在下面/content)和代码(存储在下面/apps).内容仅包含属性数据.应该没有逻辑,没有JSP(或任何其他代码)和选择器信息/content.

另一方面,/apps子树包含用于呈现内容的脚本.此类脚本通常称为组件.sling:resourceTypeproperty(为一段数据设置,under /content)是内容和组件之间的链接.这就是内容如何说"应该使用以下组件来展示我"的方式.

sling:resourceSuperType有不同的功能.它是在组件资源(下/apps)上设置的属性,用于标记此组件应继承JSP和另一个组件.此属性允许创建组件层次结构.

根据评论中的链接,也可以在下面放入sling:resourceSuperType数据组件/content.在这种情况下,我们强制引用的组件sling:resourceType继承自引用的组件sling:resourceSuperType.我不知道任何用例,很难.

在您的情况下,请尝试创建以下结构:

• /content/test
  • sling:resourceType = news-portal/pages/test
• /apps/news-portal/pages/test
  • 组件主资源,没有特殊属性
• /apps/news-portal/pages/test/test.jsp
  • 主JSP文件
• /apps/news-portal/pages/test/selector.jsp
  • JSP用于选择器
• /apps/news-portal/pages/test/selector/pdf.jsp
  • 选择器+ pdf扩展名
