Lock a page with current loggedin user in CQ - aem

Question

I have been working on a code to lock a page with the current logged-in user (author). I have attached a listener on the property changed event. The page is getting locked as admin instead of the current user.
Below is the code snippet that i am using to lock the page.
resourceResolver = resourceResolverFactory.getAdministrativeResourceResolver(null);
Resource res = resourceResolver.getResource(lockablePagePath);
if(res != null) {
LockManager lockManager = jrSession.getWorkspace().getLockManager();
Node lockableNode = jrSession.getNode(lockablePagePath + "/jcr:content");
if (lockManager.isLocked(lockableNode.getPath())) {
LOG.error("Page/Node is alrady Locked by ");
} else {
lockManager.lock(lockableNode.getPath(), true, false, 1000, userId);
//jrSession.save();
}
}
Kindly suggest.

You are mixing Sling (ResourceResolver) and JCR (Session) API here. Based on my experience I would recommend sticking to one (preferably Sling, as it's a higher level of abstraction).
The jrSession you're using most likely belongs to the admin user. You might need to impersonare (Session.impersonate(Credentials creds)) the user you want to lock the page.
Using Sling API, I would do something like this:
Map<String, Object> map = new HashMap<String, Object>();
map.put(ResourceResolverFactory.USER_IMPERSONATION, userId);
resourceResolver = resourceResolverFactory.getAdministrativeResourceResolver(map);
PageManager pageManager = resourceResolver.adaptTo(PageManager.class);
Page page = pageManager.getPage(lockablePagePath);
if (page.isLocked()) {
//log error
} else {
page.lock();
}
What I do here is, I retrieve an administrative resourceResolver that impersonates a given (current) user.
I've never tried it, but that's the way I'd approach the problem given the documentation.
