You can use code similar to following for setting connection timeout:

RestTemplate restTemplate = new RestTemplate();
((SimpleClientHttpRequestFactory)restTemplate.getRequestFactory()).setConnectTimeout(2000);

If your wish to set read timeout, you can have code similar to following:

((SimpleClientHttpRequestFactory)restTemplate.getRequestFactory()).setReadTimeout(2000);

The time is given in milliseconds here. For more info, you can visit the documentation page.

RestTemplateBuilder introduced since Spring 1.4 could be used to set read and connect timeout settings for RestTemplate object. Here is sample code -

final RestTemplate restTemplate =
    new RestTemplateBuilder()
        .setConnectTimeout(Duration.ofMillis(connectTimeoutMillis))
        .setReadTimeout(Duration.ofMillis(readTimeoutMillis))
        .build();

This is the right way! Other responses rely on modifying HttpClient, which can fail in runtime (i.e: implementation would not be available in your JVM). The downside: RestTemplateBuilder belongs to Spring Boot. – BeardOverflow Dec 09 '20 at 08:59

I use this approach based on these threads

int DEFAULT_TIMEOUT = 5000;
RequestConfig requestConfig = RequestConfig.custom()
 .setConnectTimeout(DEFAULT_TIMEOUT)
 .setConnectionRequestTimeout(DEFAULT_TIMEOUT)
 .setSocketTimeout(DEFAULT_TIMEOUT)
 .build();

CloseableHttpClient httpClient = HttpClients.custom() .setDefaultRequestConfig(requestConfig) .build();

Spring RestTemplate Connection Timeout is not working

Java : HttpClient 4.1.2 : ConnectionTimeout, SocketTimeout values set are not effective
