is there an EL function to generate UUID using java in Gatling

I’m not sure if my proposition is optimal but I would do it in this way:

import io.gatling.javaapi.core.ScenarioBuilder;
import io.gatling.javaapi.core.Simulation;
import io.gatling.javaapi.http.HttpProtocolBuilder;

import java.util.Collections;
import java.util.Iterator;
import java.util.Map;
import java.util.UUID;
import java.util.function.Supplier;
import java.util.stream.Stream;

import static io.gatling.javaapi.core.CoreDsl.atOnceUsers;
import static io.gatling.javaapi.core.CoreDsl.scenario;
import static io.gatling.javaapi.http.HttpDsl.http;

public class FunWithFeederUUIDSimulation extends Simulation {

    HttpProtocolBuilder httpProtocol = http;

    Iterator<Map<String, Object>> feederUUID =
            Stream.generate((Supplier<Map<String, Object>>) () -> {
        String uuidString = UUID.randomUUID().toString();
        return Collections.singletonMap("uuidString", uuidString);
    }
  ).iterator();

    ScenarioBuilder scn =
            scenario("Scenario Name")
                    .feed(feederUUID)
                    .exec(session -> {
                        System.out.println("GeMi_session: " + session.toString());
                        System.out.println("GeMi_feederUUID_uuidString: " + session.get("uuidString"));
                        return session;
                    });

    {
        setUp(scn.injectOpen(atOnceUsers(10)).protocols(httpProtocol));
    }
}

Thank you @GeMi . I tried this similar code. But this one is working well.

I’ve filled a feature ticket for this: Core: add random generators to Gatling EL · Issue #4305 · gatling/gatling · GitHub

Contributions welcome.
