Trying to execute simultaneously two REST web services via RestTemplate spring MVC

Question

I'm trying to execute two (or more) REST web services at the same time with restTemplate to improve performance so i want them to be executed simultaneously, how can i do this with spring MVC ?

I mean instead of first webservice + second webservice (2 sec + 2 sec) i will have the two web services running in 2 sec together...

@GetMapping("/findClient/{name}")
public String findClient(@PathVariable String name) {

    String result1 = restTemplate.getForObject("http://localhost:8080/api/getClient1/"+name,String.class);

    String result2 = restTemplate.getForObject("http://localhost:8080/api/getClient2/"+name,String.class);

    String result = result1 + result2;
    return result;
}
