How to handle timeout for service call

Question

I have a struts based application in which I am calling my Restful Web Service. My actual service invocation looks like below:

      RestTemplate restTemplate = new RestTemplate();
      ResponseEntity<String> response = restTemplate.exchange(testUrl, httpMethod, entity, String.class);

Call go through just fine but I want to handle the scenario if in case my service is down I want to timeout in like 1 minute instead of waiting for so long.

if you use spring RestTemplate, check https://stackoverflow.com/a/15093036/6743203 — Jay Smith, Jun 20 '17 at 04:24

You can go for Spring Rest template which provide methods for timeout handling:

For connect timeout:

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

For read timeout:

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

For more information please visit the documentation page: https://docs.spring.io/spring/docs/current/javadoc-api/org/springframework/http/client/SimpleClientHttpRequestFactory.html
