Neo4JRequest on spring-data-neo4j 4.1.0.M1

Question

Following reference documentation here there is the code to update a spatial index after node insert

final CloseableHttpClient httpClient = HttpClients.createDefault();

@Bean
ApplicationListener<AfterSaveEvent> afterSaveEventApplicationListener() {
return new ApplicationListener<AfterSaveEvent>() {
    @Override
    public void onApplicationEvent(AfterSaveEvent event) {
        Neo4jRequest<String> neo4jRequest = new DefaultRequest(httpClient);
        if(event.getEntity() instanceof Person) {
            Person person = (Person) event.getEntity();
            //Construct the JSON statements
            neo4jRequest.execute(endpoint,json);
            }
        }
    };
}

the problem si: where is Neo4JRequest interface ? it seems dissappeared from the package leaving no trace on the why and how.

does anybody have the same issue with index updating?

thanks

Unfortunately, this section in the docs was not updated for 4.1 M1. Here is how to do it in SDN 4.1 (see https://github.com/spring-projects/spring-data-neo4j/issues/332)

 @Bean
    ApplicationListener<AfterSaveEvent> afterSaveEventApplicationListener() {
        return new ApplicationListener<AfterSaveEvent>() {
            @Override
            public void onApplicationEvent(AfterSaveEvent event) {

                if(event.getEntity() instanceof Person) {
                    Person person = (Person) event.getEntity();
                    String json = "construct the JSON";

                    HttpPost httpPost = new HttpPost(Components.driver().getConfiguration().getURI() + "/db/data/index/node/" + indexName);

                    try {
                        httpPost.setEntity(new StringEntity(json.toString()));
                       HttpRequest.execute(httpClient, httpPost, Components.driver().getConfiguration().getCredentials());
                    } catch (Exception e) {
                       //handle this
                    } 

                }
            }
        };
    }
