In Spring RestTemplate example, we learned to access REST APIs inside Spring application. Apache HttpClient CloseableHttpResponse tutorial with examples Previous Next. CloseableHttpClient is an abstract class which is the base implementation of HttpClient that also implements java.io.Closeable. This example demonstrates how to process HTTP responses using a response handler. To make sure the connections don't die before reuse, we should configure the client with a Keep-Alive strategy (See Example 5.1.). As a result, HttpClient will retry the same request 10 times. In this tutorial, we will test the 'Dummy Sample Rest API' which is available here. .
