What is the default timeout value when using Spring's RestTemplate?
For e.g., I am invoking a web service like this:
RestTemplate restTemplate = new RestTemplate();
String response = restTemplate.getForObject("http://webservice.com/item/3455", String.class);
Is there any built-in timeout value for RestTemplate? I am not planning to change the timeout value, however, I want to ensure that there is a reasonable timeout for every request.
You can use ClientHttpRequestFactory param in the RestTemplate constructor:
private final int HTTP_CONNECT_TIMEOUT = 15000;
private final int HTTP_READ_TIMEOUT = 10000;
private ClientHttpRequestFactory getClientHttpRequestFactory() {
HttpComponentsClientHttpRequestFactory clientHttpRequestFactory = new HttpComponentsClientHttpRequestFactory();
clientHttpRequestFactory.setConnectTimeout(HTTP_CONNECT_TIMEOUT);
clientHttpRequestFactory.setReadTimeout(HTTP_READ_TIMEOUT);
return clientHttpRequestFactory;
}
When you need a new RestTemplate, create it like this example:
RestTemplate rt = new RestTemplate(getClientHttpRequestFactory());
