Java code example for HttpClient > 4.3

package com.example.teocodownloader;

import org.apache.http.conn.ssl.NoopHostnameVerifier;
import org.apache.http.impl.client.CloseableHttpClient;
import org.apache.http.impl.client.HttpClients;
import org.springframework.http.client.HttpComponentsClientHttpRequestFactory;
import org.springframework.web.client.RestTemplate;

public class Example {
    public static void main(String[] args) {
        CloseableHttpClient httpClient
                = HttpClients.custom()
                .setSSLHostnameVerifier(new NoopHostnameVerifier())
                .build();
        HttpComponentsClientHttpRequestFactory requestFactory
                = new HttpComponentsClientHttpRequestFactory();
        requestFactory.setHttpClient(httpClient);
        RestTemplate restTemplate = new RestTemplate(requestFactory);
    }
}

By the way, don't forget to add the following dependencies to the pom file:

    org.springframework.boot
    spring-boot-starter-web


    org.springframework.boot
    spring-boot-starter-security


    org.apache.httpcomponents
    httpclient

You could find Java code example for HttpClient < 4.3 as well.
