  • 转到firefox浏览器中的URL，单击HTTPS证书链（URL地址旁边） . 单击 "more info" > "security" > "show certificate" > "details" > "export.." . 选择名称并选择文件类型example.cer . 现在你有了keystore的文件，你必须将它添加到你的JVM

  • 确定cacerts文件的位置，例如 . C:\Program Files (x86)\Java\jre1.6.0_22\lib\security\cacerts.

  • 接下来在命令行中将 example.cer 文件导入cacerts：

  keytool -import -alias example -keystore C:\Program Files (x86)\Java\jre1.6.0_22\lib\security\cacerts -file example.cer

  系统会要求您输入密码，默认为 changeit

  重新启动JVM / PC .

  经过几个小时尝试构建证书文件以使我的Java 6安装与新的twitter证书一起使用后，我终于偶然发现了一个非常简单的解决方案，其中包含一个留言板中的注释 . 只需从Java 7安装中复制cacerts文件并覆盖Java 6安装中的文件 . 可能最好先备份cacerts文件，但是你只需要复制新的文件和BOOM！它只是工作 .

  请注意，我实际上将Windows cacerts文件复制到Linux安装上，它运行得很好 .

  该文件位于新旧Java jdk安装的 jre/lib/security/cacerts 中 .

  希望这可以拯救别人几个小时的恶化 .

  我偶然发现了这个需要花费数小时研究才能修复的问题，特别是使用自动生成的证书，这与官方证书不同，它们非常棘手，而Java并不那么喜欢它们 .

  请检查以下链接：Solve Problem with certificates in Java

  基本上，您必须将证书从服务器添加到Java Home证书 .

  • 生成或获取证书并配置Tomcat以在Servers.xml中使用它

  • 下载类 InstallCert 的Java源代码并在服务器运行时执行它，提供以下参数 server[:port] . 不需要密码，因为原始密码适用于Java证书（"changeit"） .

  • 本程序将连接到服务器，Java将抛出异常，它将分析服务器提供的证书，并允许您在执行程序的目录中创建 jssecerts 文件（如果从Eclipse执行，请确保配置_2795095中的工作目录 .

  • 手动将该文件复制到 $JAVA_HOME/jre/lib/security

  执行这些步骤后，与证书的连接将不再在Java中生成异常 .

  以下源代码很重要，它从（Sun）Oracle博客中消失了，我发现它唯一的页面是在提供的链接上，因此我将其附在答案中以供参考 .

  当我的系统上存在JDK和JRE 1.8.0_112时，情况略有不同 .

  我使用已知的命令将新CA证书导入 [JDK_FOLDER]\jre\lib\security\cacerts ：

  keytool -import -trustcacerts -keystore cacerts -alias <new_ca_alias> -file <path_to_ca_cert_file>
  

  尽管如此，我仍然保持相同的PKIX路径构建失败错误 .

  我使用 java -Djavax.net.debug=all ... > debug.log 将调试信息添加到java CLI . 在debug.log文件中，以trustStore开头的行是：实际指向 [JRE_FOLDER]\lib\security\cacerts 中的cacerts存储 .

  在我的情况下，解决方案是将JDK（添加了新CA）使用的cacerts文件复制到JRE使用的文件上并修复了问题 .

  1.检查证书

  尝试在浏览器中加载目标URL并查看站点的证书（通常可以通过带有锁定符号的图标访问它 . 它位于浏览器地址栏的左侧或右侧）是否由于其他原因而过期或不受信任 .

  2.安装最新版本的JRE和JDK

  新版本通常附带更新的可信证书集 .

  如果可能的话，卸载旧版本 . 这将使错误配置错误显而易见 .

  3.检查你的组态：

  • 检查JAVA_HOME环境变量指向的位置 .

  • 检查用于运行程序的java版本 . 在IntelliJ检查中：

  • 文件 - >项目结构... - >项目设置 - >项目 - >项目SDK：

  • 文件 - >项目结构... - >平台设置 - > SDK

  4.从新Java版本复制整个密钥库

  如果您使用JDK以外的最新版本进行开发 - 尝试使用最新安装的JRE中的新文件替换 %JAVA_HOME%/jre/lib/security/cacerts 文件（首先制作备份副本），如@ jeremy-goodell在他的_2795108中建议的那样

  5.将证书添加到密钥库

  如果以上没有解决您的问题，请使用 keytool 将证书保存到Java的密钥库：

  keytool -trustcacerts -keystore "%JAVA_HOME%jre\lib\security\cacerts" -storepass changeit -importcert -alias <alias_name> -file <path_to_crt_file>
  

  带有证书的文件可以从@MagGGG在他的answer中建议的浏览器中获得 .

  注意1：您可能需要对链中的每个证书重复此操作，以获取您站点的证书 . 从根目录开始 .

  注2： <alias_name> 在商店的密钥中应该是唯一的，否则 keytool 将显示错误 .

  要获取商店中所有证书的列表，您可以运行：

  keytool -list -trustcacerts -keystore "%JAVA_HOME%jre\lib\security\cacerts" -storepass changeit
  

  如果出现问题，这将有助于您从商店中删除证书：

  keytool -delete -alias <alias_name> -keystore "%JAVA_HOME%jre\lib\security\cacerts" -storepass changeit

  Issue Background:

  当我尝试在我的项目中运行mvn clean install并通过Netbeans IDE clean和build选项时，我遇到了以下错误 . 此问题是由于我们通过NET beans IDE /通过命令提示符下载时无法使用证书，但能够通过浏览器下载文件 .

  Error ：

  Caused by: org.eclipse.aether.transfer.ArtifactTransferException: Could not transfer artifact com.java.project:product:jar:1.0.32 from/to repo-local (https://url/local-repo): sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target
  

  Resolution:

  1. Download the certificate of the Url in question:

  • "run as adminstrator"启动IE（否则，我们将无法下载证书）

  • 在IE-> https://url/local-repo中输入网址（在我的情况下，此网址包含不受信任的证书
    
    . ）

  • 单击证书错误 - >查看证书下载证书

  • 选择详细信息选项卡 - >复制到文件 - >下一步 - >选择“DER编码二进制X.509（.CER）

  • 将证书保存在某个位置，例如：c：/user/sheldon/desktop/product.cer

  • 恭喜！您已成功下载该站点的证书

  2. Now install the key store to fix the issue.

  • 运行keytool命令将下载的密钥库附加到现有证书文件中 .

  • Command: Below command in the bin folder of jdk (JAVA_HOME) .

  C：\ Program Files \ Java \ jdk1.8.0_141 \ jre \ bin> keytool -importcert -file“C：/user/sheldon/desktop/product.cer”-alias product -keystore“C：/ Program Files / Java /jdk1.8.0_141/jre/lib/security/cacerts” .

  • 系统将提示您输入密码 . 输入密钥库密码：为"Trust this certificate? [no]:"再次输入"changeit"，输入"yes"

  示例命令行命令/输出：

  keytool -importcert -file "C:/Users/sheldon/Desktop/product.cer" -alias product -keystore "C:/Program iles/Java/jdk1.8.0_141/jre/lib/security/cacerts"
  Enter keystore password:
  Trust this certificate? [no]:  yes
  Certificate was added to keystore
  

  • Contgrats！现在你应该在你的Netbeans IDE中摆脱"PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException"错误 .

  这不是Twitter特定的答案，但这是您搜索此错误时出现的问题 . 如果您的系统在连接到 appears to have a valid certificate when viewed in a web browser 的网站时收到此错误，则可能表示 that website has an incomplete certificate chain .

  有关问题的简短摘要：证书颁发机构不使用其根证书仅签署任何旧证书 . 相反，它们（通常）签署也设置了证书颁发机构标志的中间证书（即允许签署证书） . 然后，当您从CA购买证书时，他们会使用其中一个中间证书对您的CSR进行签名 .

  您的Java信任存储很可能只有根证书，而不是中间证书 .

  配置错误的网站可能只返回其签名的证书 . 问题：它是使用's not in your trust store. Browsers will handle this problem by downloading or using a cached intermediate certificate; this maximizes website compatibility. Java and tools like OpenSSL, however, won' t的中间证书签署的 . 这将导致问题中的错误 .

  您可以使用Qualys SSL Test来验证此怀疑 . 如果你针对网站运行它，它说

  此服务器的证书链不完整 .

  然后证实了这一点 . 您也可以通过查看来看到这一点认证路径和看到文本额外下载 .

  如何解决：服务器管理员需要配置Web服务器以返回中间证书 . 例如，对于Comodo来说，这就是 .ca-bundle 文件派上用场的地方 . 例如，在使用mod_ssl的Apache配置中，您将使用 SSLCertificateChainFile 配置设置 . 对于nginx，您需要连接中间证书和签名证书，并在SSL证书配置中使用它 . 您可以在线搜索"incomplete certificate chain"找到更多信息 .

  虽然其他一些答案对于这个问题的具体情况是恰当和有用的，但它们对我的问题无益和误导 .

  就我而言，问题是为其更新站点提供的URL是：

  我们得出以上错误的原因是JDK与许多可信证书颁发机构（CA）证书捆绑在一个名为'cacerts'的文件中，但是这个文件并不知道我们的自签名证书 . 换句话说，cacerts文件没有导入我们的自签名证书，因此不会将其视为可信实体，因此它会产生上述错误 .

  How to fix the above error

  要解决上述错误，我们只需将自签名证书导入cacerts文件即可 .

  首先，找到cacerts文件 . 我们需要找出JDK的位置 . 如果您通过IDE之类的IDE或IntelliJ Idea运行应用程序，请转到项目设置并找出JDK位置 . 例如，在Mac OS上，cacerts文件的典型位置将位于Window的机器上的此位置/ Library / Java / JavaVirtualMachines / {} / Contents / Home / jre / lib / security中，它位于{下} / {} / JRE / LIB /安全

  找到cacerts文件后，现在我们需要将自签名证书导入此cacerts文件 . 如果您不知道如何正确生成自签名证书，请查看上一篇文章 .

  如果您没有证书文件（.crt）并且只有.jks文件，则可以使用以下命令生成.crt文件 . 如果您已经有.crt / .pem文件，则可以忽略以下命令

  ##从密钥库生成证书（.jks文件）####

  keytool -export -keystore keystore.jks -alias selfsigned -file selfsigned.crt
  

  上面的步骤将生成一个名为selfsigned.crt.Now的文件，将证书导入cacerts
  现在将证书添加到JRE / lib / security / cacerts（trustore）

  keytool -importcert -file selfsigned.crt -alias selfsigned -keystore {{cacerts path}}
  

  例如

  keytool -importcert -file selfsigned.nextgen.crt -alias selfsigned.nextgen -keystore /Library/Java/JavaVirtualMachines/jdk1.8.0_171.jdk/Contents/Home/jre/lib/security/cacerts
  

  这就是全部，重新启动您的应用程序，它应该工作正常 . 如果它仍然不起作用并获得SSL握手异常 . 这可能意味着您使用的是不同的域，然后在证书中注册 .

  当您使用atlassian软件时遇到以上错误 . JIRA

  2018-08-18 11:35:00,312 Caesium-1-4 WARN anonymous    Default Mail Handler [c.a.mail.incoming.mailfetcherservice] Default Mail Handler[10001]: javax.mail.MessagingException: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target while connecting to host 'imap.xyz.pl' as user 'jira@xyz.pl' via protocol 'imaps, caused by: 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
  

  您可以将证书添加到其可信密钥库（将missing_ca更改为正确的证书名称）：

  keytool -importcert -file missing_ca.crt -alias missing_ca -keystore /opt/atlassian/jira/jre/lib/security/cacerts
  

  如果要求输入密码 changeit 并确认 y

  之后只需重启jira .

  如果您的存储库URL也适用于HTTP并且安全性不是问题，那么您可以转到 settings.xml （通常但不总是位于 %USERPROFILE%/.m2 中）和 replace HTTPS with HTTP 来查找 <repository> 和 <pluginRepository> URL .

  例如，这个：

  <repository>
      <snapshots>
          <enabled>false</enabled>
      </snapshots>
      <id>central</id>
      <name>libs-release</name>
      <url>https://<artifactory>/libs-release</url>
  </repository>
  

  应该替换为：

  <repository>
      <snapshots>
          <enabled>false</enabled>
      </snapshots>
      <id>central</id>
      <name>libs-release</name>
      <url>https://<artifactory>/libs-release</url>
  </repository>

  我遇到了同样的问题，并使用以下简单的步骤解决了这个问题：

  1）从谷歌下载InstallCert.java

  2）使用 javac InstallCert.java 编译它

  3）使用 java InstallCert.java 运行InstallCert.java，使用主机名和https端口，并在请求输入时按“1” . 它将“localhost”添加为可信密钥库，并生成名为“jssecacerts”的文件，如下所示：

  java InstallCert localhost:443

  4）将jssecacerts复制到$ JAVA_HOME / jre / lib / security文件夹中

  解决这个问题的主要来源是：

  通过传递arg -Djavax.net.ssl.trustStore= 我使用自己的信任存储而不是JRE

  无论信任库中的证书是什么，我都收到此错误 . 对我来说，问题是arg行传递的属性的排序 . 当我把 -Djavax.net.ssl.trustStore= 和 -Djavax.net.ssl.trustStorePassword= before -Dspring.config.location= ＆ -jar args我能够通过https成功调用我的休息呼叫 .

  如果您正在使用CloudFoundry并遇到证书问题，那么您必须确保使用包含证书的密钥库服务再次推送jar . 简单地取消绑定，绑定和重启将无效 .

  目标：

  • 使用https连接

  • 验证SSL链

  • 不处理cacerts

  • 在运行时添加证书

  • 不会丢失cacerts的证书

  怎么做：

  • 定义自己的密钥库

  • 将证书放入密钥库

  • 使用我们的自定义类重新定义SSL默认上下文

  • ???

  • 利润

  我的Keystore包装文件：

  public class CertificateManager {
  
      private final static Logger logger = Logger.getLogger(CertificateManager.class);
  
      private String keyStoreLocation;

              }
          } catch (Exception e) {
              logger.error("exception in certificate fetching as resource", e);
          }
          return null;
      }
  
      public static KeyStore createKeyStore(String keystore, String pass) throws Exception {
          try {

          }
  
          File file = new File(keystore);

          if (file.exists()) {
              keyStore.load(new FileInputStream(file), pass.toCharArray());
              logger.info("Default keystore loaded");
          } else {

          this.myTrustManager = myTrustManager;
      }
  }
  

  如有必要，此类将创建密钥库，并且可以管理其中的证书 . 现在是SSL上下文的类：

  public class CustomTrustManager implements X509TrustManager {

          return instance;
      }
  
      private X509TrustManager defaultTm;
  
      public void register(CertificateManager certificateManager) {
          for(CertificateManager manager : register) {
              if(manager == certificateManager) {
                  logger.info("Certificate manager already registered");
                  return;
              }
          }
          register.add(certificateManager);
          logger.info("New Certificate manager registered");
      }
  
      private CustomTrustManager() {
          try {
              String algorithm = TrustManagerFactory.getDefaultAlgorithm();
              TrustManagerFactory tmf = TrustManagerFactory.getInstance(algorithm);
  
              tmf.init((KeyStore) null);
              boolean found = false;
              for (TrustManager tm : tmf.getTrustManagers()) {
                  if (tm instanceof X509TrustManager) {
                      defaultTm = (X509TrustManager) tm;
                      found = true;
                      break;
                  }
              }
              if(found) {
                  logger.info("Default trust manager found");
              } else {
                  logger.warn("Default trust manager was not found");
              }
  
              SSLContext sslContext = SSLContext.getInstance("TLS");
              sslContext.init(null, new TrustManager[]{this}, null);
              SSLContext.setDefault(sslContext);
              socketFactory = sslContext.getSocketFactory();
              HttpsURLConnection.setDefaultSSLSocketFactory(socketFactory);
  
  
              logger.info("Custom trust manager was set");
          } catch (NoSuchAlgorithmException | KeyManagementException | KeyStoreException e) {
              logger.warn("Custom trust manager can't be set");
              e.printStackTrace();
          }
      }
  
      @Override
      public X509Certificate[] getAcceptedIssuers() {
          List<X509Certificate> out = new ArrayList<>();
          if (defaultTm != null) {
              out.addAll(Arrays.asList(defaultTm.getAcceptedIssuers()));
          }
          int defaultCount = out.size();
          logger.info("Default trust manager contain " + defaultCount + " certficates");
          for(CertificateManager manager : register) {
              X509TrustManager customTrustManager = manager.getMytrustManager();
              X509Certificate[] issuers = customTrustManager.getAcceptedIssuers();
              out.addAll(Arrays.asList(issuers));
          }
          logger.info("Custom trust managers contain " + (out.size() - defaultCount) + " certficates");
          X509Certificate[] arrayOut = new X509Certificate[out.size()];
          return out.toArray(arrayOut);
      }
  
      @Override
      public void checkServerTrusted(X509Certificate[] chain,
                                     String authType) throws CertificateException {
          for(CertificateManager certificateManager : register) {
              X509TrustManager customTrustManager = certificateManager.getMytrustManager();
              try {
                  customTrustManager.checkServerTrusted(chain, authType);
                  logger.info("Certificate chain (server) was aproved by custom trust manager");
                  return;
              } catch (Exception e) {
              }
          }
          if (defaultTm != null) {
              defaultTm.checkServerTrusted(chain, authType);
              logger.info("Certificate chain (server) was aproved by default trust manager");
          } else {
              logger.info("Certificate chain (server) was rejected");
              throw new CertificateException("Can't check server trusted certificate.");
          }
      }
  
      @Override
      public void checkClientTrusted(X509Certificate[] chain,
                                     String authType) throws CertificateException {
          try {
              if (defaultTm != null) {
                  defaultTm.checkClientTrusted(chain, authType);
                  logger.info("Certificate chain (client) was aproved by default trust manager");
              } else {
                  throw new NullPointerException();
              }
          } catch (Exception e) {
              for(CertificateManager certificateManager : register) {
                  X509TrustManager customTrustManager = certificateManager.getMytrustManager();
                  try {
                      customTrustManager.checkClientTrusted(chain, authType);
                      logger.info("Certificate chain (client) was aproved by custom trust manager");
                      return;
                  } catch (Exception e1) {
                  }
              }
              logger.info("Certificate chain (client) was rejected");
              throw new CertificateException("Can't check client trusted certificate.");
          }
      }
  
      public SSLSocketFactory getSocketFactory() {
          return socketFactory;
      }
  }
  

  此类作为单例生成，因为只允许一个defaultSSL上下文 . 那么，现在用法：

  CertificateManager certificateManager = new CertificateManager("C:\\myapplication\\mykeystore.jks", "changeit");
              String certificatePath = "C:\\myapplication\\public_key_for_your_ssl_service.crt";
              try {
                  certificateManager.addCustomCertificate(certificatePath, "alias_for_public_key_for_your_ssl_service");
              } catch (Exception e) {
                  log.error("Can't add custom certificate");
                  e.printStackTrace();
              }
              CustomTrustManager.getInstance().register(certificateManager);
  

  可能，它不适用于此设置，因为我将证书文件保存在资源文件夹中，所以我的路径不是绝对的 . 但一般来说，它完美地运作 .
