Java 通过Adobe Experience Manager中的UI删除数据库中未使用的DAM图像列表

我是Adobe Experience Manager的新手。我的任务是从数据库中检索未使用图像的列表，并需要通过UI将其删除

I found some code an adobe help blog that is how to delete a node or folder from jsp.

我给出了一个Select查询，其中显示了未使用图像的列表。在谷歌搜索之后，我对如何在adobe experience manager中使用QueryBuilder有了一些想法，但我不知道在下面的代码中将这个select查询放在哪里

SQLQuery = "Select * from [nt:file] 
            where isdesplay([/home/cam/Bwits/master/images/top_images]) 
            and NAME() LIKE 'cq5dam.thumbnail.140.100.png'";

下面的代码也是我从adobe支持网站获得的。对于普通Jsp，我知道如何检索文件列表，但现在对于使用adobe（AEM）api的Jsp中的相同文件，我不知道

要删除的节点路径： （例如，/content/testdelete/deletePage1'）
字符集：
命令：
强制删除： （对/错）

函数performDelete（）{
var响应=null；
var url=“/bin/wcmcommand”；
var pathbj=document.getElementById（'pathAJ'）；
if（pathbj）
{
var params=“path=”+encodeURIComponent（pathbj.value）+“&&u charset=utf-8&cmd=deletePage&force=false”；
var request=document.all？新的ActiveXObject（“Microsoft.XMLHTTP”）：新的XMLHttpRequest（）；
//警报（参数）；
打开（“post”、url、false）；
setRequestHeader（“内容类型”、“应用程序/x-www-form-urlencoded”）；
请求发送（params）；
var resp=request.responseText；
document.getElementById（'respText'）。innerHTML=resp；
}
}                               

现在，我必须借助SQL查询获取节点列表，并且需要从这个JSP中一次删除这些节点

请告诉我从数据库检索图像列表的sql查询的位置。

提前感谢您的合作

正如其他人所指出的，有几个论坛（主要是Adobe）发布了各种方法来解决这个问题。然而，本着多样性和丰富性的精神，我认为这个问题需要一个新的答案

下面的解决方案是基于JS的，但没有理由不能在任何其他语言（如Java、Ruby、bash（使用CURL）或PowerShell）中实现此逻辑。此外，这种方法不适用于从CSS和JS文件引用的DAM资产

I found some code an adobe help blog that is how to delete a node or folder from jsp.

以GooTrimxOOTB大坝库为例，考虑大部分资产在/Cyp/BAD/GraceTXXXX < /代码>文件夹

I found some code an adobe help blog that is how to delete a node or folder from jsp.

您需要构建一个递归迭代循环，该循环以线性方式一次一级遍历DAM库。这可以使用以下逻辑完成：

步骤1：枚举

I found some code an adobe help blog that is how to delete a node or folder from jsp.

通过以下HTTP调用获取内容的根级别文件夹结构：

I found some code an adobe help blog that is how to delete a node or folder from jsp.

http://localhost:4502/content/dam/geometrixx.1.json

I found some code an adobe help blog that is how to delete a node or folder from jsp.

这将返回如下结果：

I found some code an adobe help blog that is how to delete a node or folder from jsp.

{
   "jcr:primaryType":"sling:OrderedFolder",
   "jcr:mixinTypes":[
      "rep:AccessControllable"
   ],
   "jcr:createdBy":"admin",
   "jcr:title":"Geometrixx",
   "jcr:created":"Mon Feb 27 2017 13:54:20 GMT+0000",
   "portraits":{
      "jcr:primaryType":"sling:OrderedFolder",
      "jcr:createdBy":"admin",
      "jcr:title":"Portraits",
      "jcr:created":"Mon Feb 27 2017 13:54:20 GMT+0000"
   },
   "drm":{
      "jcr:primaryType":"sling:OrderedFolder",
      "jcr:createdBy":"admin",
      "jcr:created":"Mon Feb 27 2017 13:54:20 GMT+0000"
   },
   "banners":{
      "jcr:primaryType":"sling:OrderedFolder",
      "jcr:createdBy":"admin",
      "jcr:title":"Banners",
      "jcr:created":"Mon Feb 27 2017 13:54:20 GMT+0000"
   }
}

{
   "jcr:primaryType":"sling:OrderedFolder",
   "jcr:createdBy":"admin",
   "jcr:title":"Banners",
   "jcr:created":"Mon Feb 27 2017 13:54:20 GMT+0000",
   "banner-mono.png":{
      "jcr:primaryType":"dam:Asset",
      "jcr:createdBy":"admin",
      "jcr:created":"Mon Feb 27 2017 13:54:20 GMT+0000"
   },
   "banner-retro.png":{
      "jcr:primaryType":"dam:Asset",
      "jcr:createdBy":"admin",
      "jcr:created":"Mon Feb 27 2017 13:54:20 GMT+0000"
   },
   "banner-web20.png":{
      "jcr:primaryType":"dam:Asset",
      "jcr:createdBy":"admin",
      "jcr:created":"Mon Feb 27 2017 13:54:20 GMT+0000"
   }
}

步骤2：迭代

I found some code an adobe help blog that is how to delete a node or folder from jsp.

递归地遍历此结构，直到到达项目的DAM资源。例如，您在迭代时：

http://localhost:4502/content/dam/geometrixx/banners.1.json

您将得到如下结果：

I found some code an adobe help blog that is how to delete a node or folder from jsp.

{
   "jcr:primaryType":"sling:OrderedFolder",
   "jcr:mixinTypes":[
      "rep:AccessControllable"
   ],
   "jcr:createdBy":"admin",
   "jcr:title":"Geometrixx",
   "jcr:created":"Mon Feb 27 2017 13:54:20 GMT+0000",
   "portraits":{
      "jcr:primaryType":"sling:OrderedFolder",
      "jcr:createdBy":"admin",
      "jcr:title":"Portraits",
      "jcr:created":"Mon Feb 27 2017 13:54:20 GMT+0000"
   },
   "drm":{
      "jcr:primaryType":"sling:OrderedFolder",
      "jcr:createdBy":"admin",
      "jcr:created":"Mon Feb 27 2017 13:54:20 GMT+0000"
   },
   "banners":{
      "jcr:primaryType":"sling:OrderedFolder",
      "jcr:createdBy":"admin",
      "jcr:title":"Banners",
      "jcr:created":"Mon Feb 27 2017 13:54:20 GMT+0000"
   }
}

{
   "jcr:primaryType":"sling:OrderedFolder",
   "jcr:createdBy":"admin",
   "jcr:title":"Banners",
   "jcr:created":"Mon Feb 27 2017 13:54:20 GMT+0000",
   "banner-mono.png":{
      "jcr:primaryType":"dam:Asset",
      "jcr:createdBy":"admin",
      "jcr:created":"Mon Feb 27 2017 13:54:20 GMT+0000"
   },
   "banner-retro.png":{
      "jcr:primaryType":"dam:Asset",
      "jcr:createdBy":"admin",
      "jcr:created":"Mon Feb 27 2017 13:54:20 GMT+0000"
   },
   "banner-web20.png":{
      "jcr:primaryType":"dam:Asset",
      "jcr:createdBy":"admin",
      "jcr:created":"Mon Feb 27 2017 13:54:20 GMT+0000"
   }
}

因此，关键逻辑是获取文件夹节点的子节点并处理所有

dam:Asset

节点

步骤3：查找参考资料

一旦您点击了DAM资源，您就可以从中使用内置的引用查找器

http://localhost:4502/bin/wcm/references.json?path=

查找参考资料

http://localhost:4502/bin/wcm/references.json?path=/content/dam/geometrixx/banners/techsummit.jpg

I found some code an adobe help blog that is how to delete a node or folder from jsp.

将为您提供以下所有参考资料：

    {
   "pages":[
      {
         "srcPath":"/content/dam/geometrixx/banners/techsummit.jpg",
         "srcTitle":"Tech Summit",
         "path":"/content/geometrixx/en/events/techsummit",
         "title":"TechSummit",
         "references":[
            "/content/geometrixx/en/events/techsummit/jcr:content/image/fileReference",
            "/content/geometrixx/en/events/techsummit/jcr:content/par/image/fileReference"
         ],
         "published":false,
         "isPage":"true"
      }
   ]
}

包含空

步骤4：删除

I found some code an adobe help blog that is how to delete a node or folder from jsp.

删除只是节点路径上的HTTP删除请求。例如，如果要删除

/content/dam/geometrixx/banners/techsummit.jpg

dam资产，只需在以下位置发送HTTP删除请求：
