How to replace sling:resourceType value in bulk using query or script - aem

Question

How to replace sling:resourceType value in bulk using Query and Scipt.
For example I want to change sling:resourceType value
from app/component/linkButton to app/component/content/linkbutton1.
The component is being used on 20 pages, and I want change it using query rather than manually on each page.

Answer 1

the best choice for the purpose is groovy console .
Bellow script which do the job:
import javax.jcr.Node
getNode('/content/').recurse { resourceNode ->
if (resourceNode.hasProperty('sling:resourceType')) {
final def resourceType = resourceNode.getProperty('sling:resourceType').string
if (resourceType.equals('OLD_RESOURCE_TYPE')) {
println "changing " + resourceNode.path
resourceNode.setProperty('sling:resourceType', 'NEW_RESOURCE_TYPE')
resourceNode.save();
}
}
}

You can use the ACS AEM Tools open source project which includes AEM Fiddle. AEM Fiddle allows you to run scripts directly on the AEM instance without have to build.
If you use AEM Fiddle, navigate to http://localhost:4502/miscadmin#/etc/acs-tools/aem-fiddle, click the plus sign in the top right and select .java. Insert this code and run. Make sure you update the query's path.
import java.io.IOException;
import java.io.PrintWriter;
import java.util.Iterator;
import javax.jcr.query.Query;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServletResponse;
import org.apache.sling.api.SlingHttpServletRequest;
import org.apache.sling.api.SlingHttpServletResponse;
import org.apache.sling.api.resource.ModifiableValueMap;
import org.apache.sling.api.resource.Resource;
import org.apache.sling.api.resource.ResourceResolver;
import org.apache.sling.api.servlets.SlingAllMethodsServlet;
public class fiddle extends SlingAllMethodsServlet {
#Override
protected void doGet(SlingHttpServletRequest request, SlingHttpServletResponse response) throws ServletException, IOException {
response.setStatus(HttpServletResponse.SC_OK);
PrintWriter out = response.getWriter();
ResourceResolver resolver = null;
out.println("starting...");
try {
resolver = request.getResourceResolver();
if (resolver != null) {
Iterator<Resource> resources = resolver.findResources("/jcr:root/content/mysite//*[#sling:resourceType='app/component/linkButton']", Query.XPATH);
while (resources.hasNext()) {
Resource resource = resources.next();
ModifiableValueMap properties = resource.adaptTo(ModifiableValueMap.class);
properties.put("sling:resourceType", "app/component/linkButton1");
resolver.commit();
out.println(resource.getPath());
}
}
} catch(Exception e) {
response.setStatus(HttpServletResponse.SC_INTERNAL_SERVER_ERROR);
e.printStackTrace(out);
} finally {
if (resolver != null && resolver.isLive()) {
resolver.close();
resolver = null;
}
}
out.println("...finished");
}
}
If you'd rather use JSP as you've stated, the code is the same:
<%#include file="/libs/foundation/global.jsp"%><%
%><%#page session="false" contentType="text/html; charset=utf-8"
pageEncoding="UTF-8"
import="org.apache.sling.api.resource.*,
java.util.*,
javax.jcr.*,
com.day.cq.search.*,
com.day.cq.wcm.api.*,
com.day.cq.dam.api.*,
javax.jcr.query.Query,
org.apache.sling.api.resource.ModifiableValueMap"%><%
Iterator<Resource> resources = resourceResolver.findResources("/jcr:root/content/mysite//*[#sling:resourceType='app/component/linkButton']", Query.XPATH);
while (resources.hasNext()) {
Resource current = resources.next();
ModifiableValueMap props = current.adaptTo(ModifiableValueMap.class);
props.put("sling:resourceType", "app/component/linkButton1");
resourceResolver.commit();
%>
<%=current.getPath()%>
<%
}
%>

Another dirty method, but worked for me. :)
Package the path and download the zip file.
Extract to a folder.
Based on your operating system,
If using Windows, use Notepad++ to find an replace in all files under directory with your search pattern.
If linux, use find or sed commands to replace all occurrences inside a director

How about AEM ACS TOOLS?
It is bulk updating tool for sling:resourceType or cq:Template.

You can also have a look at sling pipes.
https://sling.apache.org/documentation/bundles/sling-pipes.html
this is the perfect solution for your problem
