try with

@component(service = Filter.class, name = "Custom Logging Filter", property = {
SLING_FILTER_SCOPE + "=" + FILTER_SCOPE_REQUEST, Constants.SERVICE_RANKING + ":Integer=1",
SLING_FILTER_RESOURCETYPES + "testproject/components/page/myDetailsPage" })

add SLING_FILTER_RESOURCETYPES multiple times to support different resource types

@component(service = Filter.class, name = "Custom Logging Filter", property = {
SLING_FILTER_SCOPE + "=" + FILTER_SCOPE_REQUEST, Constants.SERVICE_RANKING + ":Integer=1",
SLING_FILTER_RESOURCETYPES + "testproject/components/page/myDetailsPage",

SLING_FILTER_RESOURCETYPES + "testproject/components/page/myDetailsPage1"})

 

import static org.apache.sling.engine.EngineConstants.*; for properties

 

Regards

Hi @karthikb1706130 ,

If I understood correctly you want to create a filter which is able to get all the request that comes from a specific resourcetype or list of resourcetype.

If this is your purpose, I think that it's better for you to use a servlet instead of a filter. In this way you can use also multiple resourcetype without problems [0].

 

A suggestion, don't use a filter if it's not required since this filter will be executed every time for each request (also the AEM default request) and then will evaluate the conditions.

Hi @karthikb1706130,

Looks like the resource type to be mentioned in sling.filter.resourceTypes is jcr:primaryType of the resource and not sling:resourceType

For your case, if the pages created using myDetailsPage is created/resides under one hierarchy, then we can restrict the filter using sling.filter.pattern property.

Sample below will apply the filter to pages under /content/learnings

dam:Asset type will not take effect given the pattern. Have just added to showcase the multiple resource types (similar to what @albinissac said)

 

@Component(service = Filter.class,
           property = {
                   EngineConstants.SLING_FILTER_SCOPE + "=" + EngineConstants.FILTER_SCOPE_REQUEST,
                   EngineConstants.SLING_FILTER_PATTERN + "=/content/learnings/(.*)",            
                   EngineConstants.SLING_FILTER_RESOURCETYPES + "=cq:Page",  
                   EngineConstants.SLING_FILTER_RESOURCETYPES + "=dam:Asset", 
                   Constants.SERVICE_RANKING + "=500",
           })
