Java HTTPComponents SOAP请求，SSLHandshake异常（PKIX路径构建失败）

Question

我正在尝试使用HTTPComponents将自定义SOAP消息发送到特定的Web服务。 我们使用证书进行通信，而Web服务端点使用证书进行https加密。

通过一个自定义的Java操作，我试图发送SOAP消息，但是在执行httppost的时候抛出了一个错误：

Executing request POST https://webserviceurl/endpoint HTTP/1.1
Exception While Connecting sun.security.validator.ValidatorException: PKIX path building failed:     sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested     target
javax.net.ssl.SSLHandshakeException: sun.security.validator.ValidatorException: PKIX path building failed:      sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target
at sun.security.ssl.Alerts.getSSLException(Alerts.java:192)

我对此问题进行了一些研究，显然Java需要在cacerts中用于Web服务URL的证书。 使用名为InstallCert的Java工具，我尝试将证书添加到cacerts，但是仍然出现此错误。

PS：我也尝试使用keytool将证书添加到cacerts，但是也没有运气。

那么为什么连接失败。 我需要将端点证书添加到cacerts文件中是否正确？ 关于如何解决此问题/如何将证书成功添加到受信任证书的任何想法？

这是我执行请求的完整Java代码：

 // Trust own CA and all self-signed certs
    SSLContext sslcontext = SSLContexts.custom()
            .loadTrustMaterial(new File("C:/ourcert.p12"), "MyPass".toCharArray(),
                    new TrustSelfSignedStrategy())
            .build();        

    // Allow TLSv1 protocol only
    SSLConnectionSocketFactory sslsf = new SSLConnectionSocketFactory(
            sslcontext,
            new String[] { "TLSv1" },
            null,
            SSLConnectionSocketFactory.getDefaultHostnameVerifier());

    CloseableHttpClient httpclient = HttpClients.custom()
            .setSSLSocketFactory(sslsf)
            .build();


    Byte[] result = null;
    HttpParams httpParameters = new BasicHttpParams();
    // Set the timeout in milliseconds until a connection is established.
    int timeoutConnection = 15000;
    HttpConnectionParams.setConnectionTimeout(httpParameters, timeoutConnection);
    // Set the default socket timeout (SO_TIMEOUT)
    // in milliseconds which is the timeout for waiting for data.
    int timeoutSocket = 35000;
    HttpConnectionParams.setSoTimeout(httpParameters, timeoutSocket);         

    byte[] result1 = null; 


        HttpPost httppost = new HttpPost(webserviceUrl);
        httppost.setHeader("soapaction", "aanleveren");
        httppost.setHeader("Content-Type", "text/xml; charset=utf-8");


        System.out.println("Executing request " + httppost.getRequestLine());

        try {
             HttpEntity entity = new StringEntity(soapBericht,HTTP.UTF_8);
             httppost.setEntity(entity); 
             HttpResponse response = httpclient.execute(httppost);// calling server
             HttpEntity r_entity = response.getEntity();  //get response
             if (r_entity != null) {       
                 result1 = new byte[(int) r_entity.getContentLength()];  
                 if (r_entity.isStreaming()) {
                     DataInputStream is = new DataInputStream(
                             r_entity.getContent());
                     is.readFully(result1);
                 }
             }

            EntityUtils.consume(entity);
        } catch (Exception E) {
            Core.getLogger("SBR").log(LogLevel.WARNING,"ERROR " + E.getMessage() + E.getStackTrace());
            System.out.println("Exception While Connecting " +E.getMessage());
            E.printStackTrace();
        }

        httpclient.close(); //shut down the connection

与其将其添加到系统根证书中，不如尝试将其添加到您的应用程序信任中。

keytool -import -alias <ALIAS_NAME> -keystore <your_app_trust>.jks -trustcacerts -file <CERTIFICATE_TO_ADD.der> -v

我有同样的问题，它解决了我的问题。

使用自签名证书时的一种非常常见的情况。尝试以下操作：

                SSLContext sslContext = null;
                try
                {
                    sslContext = new SSLContextBuilder().loadTrustMaterial(null, new TrustSelfSignedStrategy() {
                        @Override
                        public boolean isTrusted(X509Certificate[] arg0, String arg1) throws CertificateException
                        {
                            return true;
                        }

                    }).build();
                }
                catch (KeyManagementException | NoSuchAlgorithmException | KeyStoreException e)
                {
                    //Show some Msg
                }
                CloseableHttpClient httpClient = HttpClients.custom()
                                                            .setDefaultHeaders(headers)
                                                            .setSSLContext(sslContext)
                                                            .setSSLHostnameVerifier(new NoopHostnameVerifier())
                                                            .build();
