春天4.0.0与RestTemplate基本身份验证 [英] Spring 4.0.0 basic authentication with RestTemplate

问题描述

我目前正在与我们的本地报表系统第三方应用程序的集成。我想实现REST与基本身份验证，但在春季4.0.0面临的问题，来电。我有一个简单的解决方案是什么工作得很好：

I am currently working on integration of a third party application with our local reporting system. I would like to implement REST calls with basic authentication but facing issues in Spring 4.0.0. I have a simple solution what works nicely:

final RestTemplate restTemplate = new RestTemplate();
final String plainCreds = "username:password";
final byte[] plainCredsBytes = plainCreds.getBytes();
final byte[] base64CredsBytes = Base64.encodeBase64(plainCredsBytes);
final String base64Creds = new String(base64CredsBytes);

final HttpHeaders headers = new HttpHeaders();
headers.add("Authorization", "Basic " + base64Creds);
final HttpEntity<String> request = new HttpEntity<String>(headers);

final ResponseEntity<MyDto> response = restTemplate.exchange("myUrl", HttpMethod.GET, request, MyDto.class);
final MyDto dot = response.getBody();

但希望改写这个来使用 ClientHtt prequestFactory 以下列方式：

final RestTemplate restTemplate = new RestTemplate(createSecureTransport("username", "password"));

private ClientHttpRequestFactory createSecureTransport(final String username, final String password) {
    final HttpClient client = new HttpClient();
    final UsernamePasswordCredentials credentials = new UsernamePasswordCredentials(username, password);
    client.getState().setCredentials(new AuthScope(null, 9090, AuthScope.ANY_REALM), credentials);
    return new CommonsClientHttpRequestFactory(client);
}

这code未编译为 CommonsClientHtt prequestFactory 类不再在Spring 4.0.0存在。难道有人知道任何替代解决方案呢？我很新在这个世界上的REST因此任何帮助将AP preciated。

This code is not compiling as the CommonsClientHttpRequestFactory class not exists anymore in Spring 4.0.0. Do somebody know any alternative solution to this? I am quite new in this REST world therefore any help will be appreciated.

推荐答案

为什么不检查弹簧4的API，看看哪些类实现所需的接口，即<一个href=\"http://docs.spring.io/spring/docs/4.0.2.RELEASE/javadoc-api/org/springframework/http/client/ClientHtt$p$pquestFactory.html\"相对=nofollow> ClientHtt prequestFactory ？

Why not check the Spring 4 APIs to see which classes implement the required interface, namely ClientHttpRequestFactory?

正如你从Javadoc中看到，最有可能你想要的 HttpComponentsClientHtt prequestFactory ，它使用客户端从Apache的HttpComponents，继承老公地的HttpClient 。

As you'll see from the Javadoc, most likely you want HttpComponentsClientHttpRequestFactory, which uses the client from Apache's HttpComponents, the successor to the old commons HttpClient.
