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 void checkClientTrusted(
                java.security.cert.X509Certificate[] arg0, String arg1)
                throws CertificateException {
            // TODO Auto-generated method stub

        }
        public void checkServerTrusted(
                java.security.cert.X509Certificate[] arg0, String arg1)
                throws CertificateException {
            // TODO Auto-generated method stub

        }
    }
};

public static void main(String[] args) {
    TrustStrategy acceptingTrustStrategy = 

    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);
    String url = "https://api.stubhubsandbox.com/search/catalog/events/v3";
    RestTemplate rest = new RestTemplate();
    Map<String, String> mvm = new HashMap<String, String>();
    mvm.put("Authorization", "Bearer TOKEEEEEEEN");
    Object object = rest.postForObject(url, null, Object.class, mvm);
    System.err.println("done");

Answer 1

您可能已经注意到,Spring RestTemplate将所有与HTTP(S)相关的内容委托给底层实现ClientHttpRequestFactory.由于您使用的是HttpClient基于实现的实现,因此以下是有关如何为内部实现此功能的一些有用的SO链接HttpClient:

• 忽略Apache HttpClient 4.3中的SSL证书
• 如何忽略Apache HttpClient 4.0中的SSL证书错误

显然,从版本4.4开始,可以这样做:

CloseableHttpClient httpClient = HttpClients.custom().setSSLHostnameVerifier(NoopHostnameVerifier.INSTANCE).build();

为了绕过几个spring项目中的SSL检查,我总是重复使用我之前与spring的RestTemplate一起编写(或找到)的SSLUtils类.使用下面提供的类,您只需SSLUtil.turnOffSslChecking()在发送请求之前调用静态方法.

import javax.net.ssl.*;
import java.security.*;
import java.security.cert.CertificateException;
import java.security.cert.X509Certificate;

public final class SSLUtil{

    static {
        //for localhost testing only
        javax.net.ssl.HttpsURLConnection.setDefaultHostnameVerifier(
        new javax.net.ssl.HostnameVerifier(){

            public boolean verify(String hostname,
                    javax.net.ssl.SSLSession sslSession) {
                if (hostname.equals("localhost")) {
                    return true;
                }
                return false;
            }
        });
    }

    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.");
    }
}

试试看.希望这可行,并为您提供简单的解决方案.

将SSLContext和X509TrustManager以及HostnameVerifier实例添加到http ClientBuilders.例如,他们可以(举个例子)

1. HttpClientBuilder与HttpComponentsClientHttpRequestFactory
2. OkHttpClient.Builder与OkHttp3ClientHttpRequestFactory

这是Apache HttpClient和OkHttpClient的示例代码.它用于演示目的,但您可以使用它

Apache HttpClient

RestTemplate restTemplate = new RestTemplate(SSLClientFactory.getClientHttpRequestFactory(HttpClientType.HttpClient));

和OkHttpClient

RestTemplate restTemplate = new RestTemplate(SSLClientFactory.getClientHttpRequestFactory(HttpClientType.OkHttpClient));

SSLClientFactory是这里的自定义类

import java.security.KeyManagementException;
import java.security.NoSuchAlgorithmException;
import java.security.cert.CertificateException;
import java.security.cert.X509Certificate;
import java.util.concurrent.TimeUnit;

import javax.net.ssl.HostnameVerifier;
import javax.net.ssl.SSLContext;
import javax.net.ssl.SSLSession;
import javax.net.ssl.TrustManager;
import javax.net.ssl.X509TrustManager;

import org.apache.http.impl.client.HttpClientBuilder;
import org.springframework.http.client.ClientHttpRequestFactory;
import org.springframework.http.client.HttpComponentsClientHttpRequestFactory;
import org.springframework.http.client.OkHttp3ClientHttpRequestFactory;

import okhttp3.OkHttpClient;

public abstract class SSLClientFactory {

    private static boolean allowUntrusted = false;
    private static final long LOGIN_TIMEOUT_SEC = 10;
    private static HttpClientBuilder closeableClientBuilder = null;
    private static OkHttpClient.Builder okHttpClientBuilder = null;

    public enum HttpClientType{
        HttpClient,
        OkHttpClient
    } 


    public static synchronized ClientHttpRequestFactory getClientHttpRequestFactory(HttpClientType httpClientType){

        ClientHttpRequestFactory requestFactory = null;

        SSLContext sslContext = SSLClientFactory.getSSlContext();

        if(null == sslContext){
            return requestFactory;
        }

        switch (httpClientType) {

        case HttpClient:
            closeableClientBuilder = HttpClientBuilder.create();

            //Add the SSLContext and trustmanager
            closeableClientBuilder.setSSLContext(getSSlContext());
            //add the hostname verifier
            closeableClientBuilder.setSSLHostnameVerifier(gethostnameVerifier());   

            requestFactory = new HttpComponentsClientHttpRequestFactory(closeableClientBuilder.build());

            break;
        case OkHttpClient:
            okHttpClientBuilder = new OkHttpClient().newBuilder().readTimeout(LOGIN_TIMEOUT_SEC, TimeUnit.SECONDS);

            //Add the SSLContext and trustmanager
            okHttpClientBuilder.sslSocketFactory(getSSlContext().getSocketFactory(), getTrustManager());
            //add the hostname verifier
            okHttpClientBuilder.hostnameVerifier( gethostnameVerifier());

            requestFactory = new OkHttp3ClientHttpRequestFactory(okHttpClientBuilder.build());

            break;
        default:
            break;
        }

        return requestFactory;

    }


    private static SSLContext getSSlContext(){



        final TrustManager[] trustAllCerts = new TrustManager[]{getTrustManager()};

        SSLContext sslContext = null;
        try {

            sslContext = SSLContext.getInstance("SSL");
            sslContext.init(null, trustAllCerts, new java.security.SecureRandom());

        } catch (NoSuchAlgorithmException | KeyManagementException e) {
            e.printStackTrace();
        }



        return sslContext;

    }

    private static X509TrustManager getTrustManager(){

        final X509TrustManager trustManager = new X509TrustManager() {

            @Override
            public X509Certificate[] getAcceptedIssuers() {
                X509Certificate[] cArrr = new X509Certificate[0];
                return cArrr;
            }

            @Override
            public void checkServerTrusted(X509Certificate[] chain, String authType) throws CertificateException {
                // TODO Auto-generated method stub

            }

            @Override
            public void checkClientTrusted(X509Certificate[] chain, String authType) throws CertificateException {
                // TODO Auto-generated method stub

            }
        };

        return trustManager;
    }

    private static HostnameVerifier gethostnameVerifier(){

        HostnameVerifier hostnameVerifier = new HostnameVerifier() {

            @Override
            public boolean verify(String arg0, SSLSession arg1) {
                return true;
            }
        };

        return hostnameVerifier;

    }

}

不确定jdk6之后是否有变化,但上次我尝试这样做时,我们需要将SSL证书导入到JAVA_HOME的密钥库中,该密钥库用于使用受信任的ssl运行程序.

首先,您需要将证书导出到文件.在Windows中,您可以使用任何浏览器将SSL证书保存到个人证书存储区,然后运行mmc,添加证书snapin(文件/添加删除Snapin)并将证书保存到磁盘.

然后,您需要使用keytool将证书导入受信任的域cacerts .但是您需要将它导入到java_home在运行上述程序时使用的密钥库.

下面的命令将证书文件"mycertificate.cer"添加到文件"cacerts.jks"中的密钥库.别名是"webservice":

"%JAVA_HOME%\bin\keytool" -import -trustcacerts -alias webservice -file mycertificate.cer -keystore cacerts.jks

通常,密钥库密码是"changeit",没有引号.将其更改为生产用途
