When I get request form path for example /bar is it possible in spring cloud gateway to call multiple microservices and integrate their result (for example JSON) and send as response of /bar ? How can i do it? thanks

You can use ProxyExchange to help you composition multiple responses.
An example given by Spring Cloud:
@RestController
@SpringBootApplication
public class GatewaySampleApplication {
@Value("${remote.home}")
private URI home;
@GetMapping("/test")
public ResponseEntity<?> proxy(ProxyExchange<byte[]> proxy) throws Exception {
return proxy.uri(home.toString() + "/image/png").get();
}
}
In this case it is only used to return the ResponseEntity, but you can use it however you like. In your case you can combine multiple ResponseEntities.
