Spring Boot Rest API - Request Timeout

Spring Boot REST API - request timeout?

You need to return a Callable<> if you want spring.mvc.async.request-timeout=5000 to work.

@RequestMapping(method = RequestMethod.GET)
public Callable<String> getFoobar() throws InterruptedException {
    return new Callable<String>() {
        @Override
        public String call() throws Exception {
            Thread.sleep(8000); //this will cause a timeout
            return "foobar";
        }
    };
}

Spring Boot Application - what is default timeout for any rest API endpoint or a easy config to control all endpoint timeout

I agree all above options and tried below option in my spring boot application. It works perfectly fine now. Below is the code sample as a bean. Now just need to @Autowire RestTemplate wherever(java class) I need it.

   @Bean
    public RestTemplate restTemplate() {
        RestTemplate restTemplate = new RestTemplate();
        ((SimpleClientHttpRequestFactory) restTemplate.getRequestFactory()).setConnectTimeout(15000);
        ((SimpleClientHttpRequestFactory) restTemplate.getRequestFactory()).setReadTimeout(15000);

        return restTemplate;
    }
