Using sping's restTemplate with a timeout, how do I detect a timeout?

I've initialized my restTemplate as follows:

HttpClient httpClient = HttpClientBuilder.create().build();
HttpComponentsClientHttpRequestFactory requestFactory = new HttpComponentsClientHttpRequestFactory(httpClient);
requestFactory.setConnectTimeout(1000);
requestFactory.setReadTimeout(1000);
restTemplate = new RestTemplate(requestFactory);

and I'm calling it like so:

restTemplate.getForEntity(someString, String.class, SomeHashmapWithURLParameters)

How do I handle both timeouts? I assume an exception will be thrown? If so which specific exception can I catch, in order to specifically handle just timeouts. I'm handeling other exceptions in different ways.

In case of RestTemplate, when the request gets timed out, Spring will throw ResourceAccessException. Underlying exception under that instance will be java.net.SocketTimeoutException with message 'Read timed out'.
