我正在尝试编写一个集成测试，其中我们的测试使用简单启动一个嵌入式HTTPS服务器。我keytool并能够使用浏览器访问服务器(特别是Chrome，我确实收到了关于自签名证书的警告)。

然而，当我尝试使用弹簧RestTemplate连接时，我得到了一个ResourceAccessException：

代码语言：javascript
运行

在其他问题和博客 帖子中，我看到了用以下内容替换HostnameVerifier的建议

代码语言：javascript
运行
复制
private static final HostnameVerifier PROMISCUOUS_VERIFIER = ( s, sslSession ) -> true;

我已经在全球范围和RestTemplate本身上设置了它：

代码语言：javascript
运行
复制
HttpsURLConnection.setDefaultHostnameVerifier( PROMISCUOUS_VERIFIER );

...and在RestTemplate本身上：

代码语言：javascript
运行
复制
final RestTemplate restTemplate = new RestTemplate();
restTemplate.setRequestFactory( new SimpleClientHttpRequestFactory() {
    @Override
    protected void prepareConnection(HttpURLConnection connection, String httpMethod) throws IOException {
        if(connection instanceof HttpsURLConnection ){
            ((HttpsURLConnection) connection).setHostnameVerifier(PROMISCUOUS_VERIFIER);
        }
        super.prepareConnection(connection, httpMethod);
    }
});

然而，我仍然得到上述错误。我怎么才能绕过它？

  1. 在单元测试之外本地安装证书不是一个选项，因为它需要手动安装在每台dev机器和构建服务器上，并且会导致大量的繁文缛节。
  2. 我们需要SSL，因为我们正在测试位于RestTemplate之上的库，并且我们正在正确地配置它。

我使用的是Java 8(但可以使用7)和Spring4.0.3。

我希望我仍然有一个指向引导我朝这个方向前进的源的链接，但是这是最终为我工作的代码。通过查看JavaDoc for X509TrustManager，看起来TrustManager的工作方式是在成功验证时不返回任何内容，否则会引发异常。因此，对于零实现，它被视为一个成功的验证。然后删除所有其他实现。

代码语言：javascript
运行
复制
import javax.net.ssl.*;
import java.security.*;
import java.security.cert.X509Certificate;

public final class SSLUtil{

    private static final TrustManager[] UNQUESTIONING_TRUST_MANAGER = new TrustManager[]{
            new X509TrustManager() {
                public java.security.cert.X509Certificate[] getAcceptedIssuers(){
                    return null;
                }
                public void checkClientTrusted( X509Certificate[] certs, String authType ){}
                public void checkServerTrusted( X509Certificate[] certs, String authType ){}
            }
        };

    public  static void turnOffSslChecking() throws NoSuchAlgorithmException, KeyManagementException {
        // Install the all-trusting trust manager
        final SSLContext sc = SSLContext.getInstance("SSL");
        sc.init( null, UNQUESTIONING_TRUST_MANAGER, null );
        HttpsURLConnection.setDefaultSSLSocketFactory(sc.getSocketFactory());
    }

    public static void turnOnSslChecking() throws KeyManagementException, NoSuchAlgorithmException {
        // Return it to the initial state (discovered by reflection, now hardcoded)
        SSLContext.getInstance("SSL").init( null, null, null );
    }

    private SSLUtil(){
        throw new UnsupportedOperationException( "Do not instantiate libraries.");
    }
}

为了其他开发人员，他们发现了这个问题，并且需要另一种不仅适合单元测试的解决方案：

我在博客上找到了这 (不是我的解决方案！)归功于博客的所有者)。

代码语言：javascript
运行
复制
TrustStrategy acceptingTrustStrategy = (X509Certificate[] chain, String authType) -> true;

SSLContext sslContext = org.apache.http.ssl.SSLContexts.custom()
        .loadTrustMaterial(null, acceptingTrustStrategy)
        .build();

SSLConnectionSocketFactory csf = new SSLConnectionSocketFactory(sslContext);

CloseableHttpClient httpClient = HttpClients.custom()
        .setSSLSocketFactory(csf)
        .build();

HttpComponentsClientHttpRequestFactory requestFactory =
        new HttpComponentsClientHttpRequestFactory();

requestFactory.setHttpClient(httpClient);

RestTemplate restTemplate = new RestTemplate(requestFactory);

请参阅下面对@Sled代码的适度改进，该方法缺少一行，现在它通过了我的测试。在Spring 2应用程序中使用RestTemplate时，将禁用HTTPS证书和主机名欺骗，该应用程序使用默认的HTTP配置，而不是配置为使用Apache客户端。

代码语言：javascript
运行

public final class SSLUtils {

    private static final HostnameVerifier jvmHostnameVerifier = HttpsURLConnection.getDefaultHostnameVerifier();

    private static final HostnameVerifier trivialHostnameVerifier = new HostnameVerifier() {
        public boolean verify(String hostname, SSLSession sslSession) {
            return true;
        }
    };

    private static final TrustManager[] UNQUESTIONING_TRUST_MANAGER = new TrustManager[] { new X509TrustManager() {
        public java.security.cert.X509Certificate[] getAcceptedIssuers() {
            return null;
        }

        public void checkClientTrusted(X509Certificate[] certs, String authType) {
        }

        public void checkServerTrusted(X509Certificate[] certs, String authType) {
        }
    } };

    public static void turnOffSslChecking() throws NoSuchAlgorithmException, KeyManagementException {

        sc.init(null, UNQUESTIONING_TRUST_MANAGER, null);
        HttpsURLConnection.setDefaultSSLSocketFactory(sc.getSocketFactory());
    }
