The following code snippet shows how this could be done with anApache Camel route configuration:

public class SimpleRoute extends RouteBuilder {    @Override    public void configure() {        from("amqpConnection:topic:alfresco.repo.event2")            .id("CreatedFileRoute")            .log("${body}")             .choice()             .when() // When the following is true:                // The event type is node created                .jsonpath("$[?(@.type=='org.alfresco.event.node.Created' && " +                   // The node that was created is a file                "@.data.resource.nodeType=='cm:content' && " +                            // The file is located in the /Company Home/Testing/Inbound folder                "'5f355d16-f824-4173-bf4b-b1ec37ef5549' in @.data.resource.primaryHierarchy[:1])]")            // Unpack the data into JSON format              .unmarshal("publicDataFormat")            // Call a Spring Bean with the event data             .bean("eventHandlerImpl", "onReceive(*, COPY)")             .end();    }}

Thejsonpath expression uses several of the event data properties to filter out exactly the events we are interested in.

In this case a Spring Bean with IDeventHandlerImpl is called at the end of the route from where you could make the necessary ReST API calls.

Note that you can get to the property values before the update via therepoEvent.getData().getResourceBefore() call.You can compare those to the values retreived viarepoEvent.getData().getResource() and see what’s changed.

This code uses a customParentFolderFilter.

To create an SDK event handler project that uses Spring Integration followthese instructions.

The following code snippet shows how this could be done with anApache Camel route configuration:

public class SimpleRoute extends RouteBuilder {    @Override    public void configure() {        from("amqpConnection:topic:alfresco.repo.event2")            .id("ParentChildAssocDeletedRoute")            .log("${body}") // Log all incoming events on this topic, even those that we are not interested in            .choice()            .when() // When the following is true:            // The event type is parent-child assoc deleted            .jsonpath("$[?(@.type=='org.alfresco.event.assoc.child.Deleted' && " +                    // and the association type is fdk:images                    "@.data.resource.assocType=='fdk:images')]" )            // Unpack the data into JSON format            .unmarshal("publicDataFormat")            // Call a Spring Bean with the event data            .bean("parentChildAssocDeletedEventHandlerImpl", "onReceive(*, COPY)")            .end();    }}

Thejsonpath expression uses several of the event data properties to filter out exactly the events we are interested in.

In this case a Spring Bean with IDparentChildAssocDeletedEventHandlerImpl is called at the end of the route from where you could make the necessary ReST API calls.

The following code shows how this can be done with SDK 5 and plain Java event handlers:

import org.alfresco.event.sdk.handling.filter.AssocTypeFilter;import org.alfresco.event.sdk.handling.filter.EventFilter;import org.alfresco.event.sdk.handling.handler.OnPeerAssocCreatedEventHandler;import org.alfresco.event.sdk.model.v1.model.*;import org.slf4j.Logger;import org.slf4j.LoggerFactory;import org.springframework.stereotype.Component;/*** Sample event handler to demonstrate reacting to a peer-2-peer assoc being created.*/@Componentpublic class Peer2PeerAssocCreatedEventHandler implements OnPeerAssocCreatedEventHandler {    private static final Logger LOGGER = LoggerFactory.getLogger(Peer2PeerAssocCreatedEventHandler.class);    public void handleEvent(final RepoEvent<DataAttributes<Resource>> repoEvent) {        PeerAssociationResource resource = (PeerAssociationResource) repoEvent.getData().getResource();        LOGGER.info("A Peer-Peer association was created: Source {} -> Target {}", resource.getSource().getId(),                resource.getTarget().getId());    }    public EventFilter getEventFilter() {        return AssocTypeFilter.of("fdk:reviews"); // Make sure the Peer-Peer association is of type FDK Reviews    }}

This code uses theorg.alfresco.event.sdk.handling.filter.AssocTypeFilter event filter to specify what type of Peer-2-Peer association we are interested in.
