Creating a resource resolver

}
}
Creating a service
@Component(service = ResourceResolverService.class, immediate = true)
public class ResourceResolverServiceImpl implements ResourceResolverService {
private static final String SYSTEM_USER = "practiceService";
@Reference
ResourceResolverFactory resourceResolverFactory;
@Override
public ResourceResolver getResourceResolver() throws LoginException {
Map<String, Object> param = new HashMap<>();
param.put(ResourceResolverFactory.SUBSERVICE, SYSTEM_USER);
return resourceResolverFactory.getServiceResourceResolver(param);
}
@Component(service = ResourceResolverService.class, immediate = true)
public class ResourceResolverServiceImpl implements ResourceResolverService {
private static final String SYSTEM_USER = "practiceService";
@Reference
ResourceResolverFactory resourceResolverFactory;
@Override
public ResourceResolver getResourceResolver() throws LoginException {
Map<String, Object> param = new HashMap<>();
param.put(ResourceResolverFactory.SUBSERVICE, SYSTEM_USER);
return resourceResolverFactory.getServiceResourceResolver(param);
}
}
Using it in another class.
@Reference
ResourceResolverService resourceResolverService;
try (ResourceResolver resourceResolver = resourceResolverService.getResourceResolver()) {
// Code Implementation
} catch (Exception e) {
LOGGER.error("Exception occurred: {}", e.getMessage());
}
ResourceResolverService resourceResolverService;
try (ResourceResolver resourceResolver = resourceResolverService.getResourceResolver()) {
// Code Implementation
} catch (Exception e) {
LOGGER.error("Exception occurred: {}", e.getMessage());
}

Updating Node in CRX repository
Method 1, Programmatically Update AEM JCR nodes in JAVA with org.apache.sling.api.resource.ModifiableValueMap
@Reference
ResourceResolverService resourceResolverService;
ResourceResolverService resourceResolverService;
try (ResourceResolver resolver = resourceResolverService.getResourceResolver()) {
Resource resource = resolver.getResource("/content/sourcedcode/jcr:content");
if (Objects.nonNull(resource)) {
ModifiableValueMap map = resource.adaptTo(ModifiableValueMap.class);
map.put("newProperty", "value");
map.put("existingProperty", "value");
map.remove("existingProperty"); //remove
resolver.commit();
}
} catch (Exception e) {
e.printStackTrace();
}
Method 2, Programmatically Update AEM JCR nodes in JAVA with,
javax.jcr.Node
@Reference
ResourceResolverService resourceResolverService;
ResourceResolverService resourceResolverService;
try (ResourceResolver resolver = resourceResolverService.getResourceResolver()) {
Session session = resolver.adaptTo(Session.class);
Node contentNode = session.getNode("/content/sourcedcode/jcr:content");
if (Objects.nonNull(contentNode)) {
contentNode.setProperty("newProperty", "value");
contentNode.setProperty("existingProperty", "value");
contentNode.setProperty("existingProperty", (Value)null); //remove
session.save();
}
} catch (Exception e) {
e.printStackTrace();
}
Create the API service
This service create a sample page in Adobe Experience Manager(AEM).

if (properties != null) {
properties.put(propertyName, newValue);
resourceResolver.commit();
System.out.println("Page property updated successfully.");
} else {
System.out.println("Failed to adapt page resource to ValueMap.");
}
} else {
System.out.println("Page does not exist.");
}
}
