apache http client org.apache.http.NoHttpResponseException: The target server failed to respond

Question

I am using apache http client to test my WS. I have write a get WS in jersey. URL for this WS is

http://localhost:8080/mobilestore/rest/sysgestockmobilews/g         


        

Answer 1

I went through the links from here and got to this answer: get NoHttpResponseException for load testing

That set me on the right track. To update the answer a bit here is the solution using the current http-client 4.5 API:

private final HttpComponentsClientHttpRequestFactory requestFactory = new HttpComponentsClientHttpRequestFactory(createHttpClient());

private CloseableHttpClient createHttpClient() {
    return HttpClients.custom().setRetryHandler((exception, executionCount, context) -> {
            if (executionCount > 3) {
                LOGGER.warn("Maximum tries reached for client http pool ");
                return false;
            }
            if (exception instanceof org.apache.http.NoHttpResponseException) {
                LOGGER.warn("No response from server on " + executionCount + " call");
                return true;
            }
            return false;
        }).build();
}

I also use spring-web there so I used the client as a parameter for RestTemplate factory since I want it to be used in the RestTemplate.
