接受的答案不适用于Mac，因为Mac (Chrome或Firefox)中没有导出按钮。请检查此答案以下载证书，并按照以下步骤执行:

列出keystore中安装的所有证书:

cd $JAVA_HOME/lib/security
keytool -list -keystore cacerts

注:

密钥库的默认密码为:changeit。 对于Java-8或以下版本，请使用cd $JAVA_HOME/jre/lib/security命令

在将证书导入密钥存储库之前，请备份密钥存储库:

sudo cp cacerts cacerts.bak

将下载的证书导入keystore:

sudo keytool -importcert -alias youralias -file /path/to/the/downloaded/certificate -keystore cacerts

检查证书是否存储在密钥存储库中:

sudo keytool -list -keystore cacerts -alias youralias

如果你想看到更详细的信息，添加-v标志:

sudo keytool -v -list -keystore cacerts -alias youralias

目标:

使用HTTPS连接 验证SSL链 不处理仙人掌 在运行时添加证书 不从cacerts丢失证书

怎么做:

定义自己的密钥库 将证书放入密钥库 使用自定义类重新定义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;
    private String keyStorePassword;
    private X509TrustManager myTrustManager;

    }

        tmf.init((KeyStore) null);
        Certificate certificate = myTrustStore.getCertificate(certificateAlias);
        if (certificate == null) {
            logger.info("Certificate not exists");
            addCertificate(certFileName, certificateAlias);
        } else {

                logger.info("Trust manager found");
                break;
            }
        }
    }

    private InputStream fullStream(String fname) throws IOException {
        ClassLoader classLoader = getClass().getClassLoader();
        InputStream resource = classLoader.getResourceAsStream(fname);
        try {

                DataInputStream dis = new DataInputStream(resource);
                byte[] bytes = new byte[dis.available()];
                dis.readFully(bytes);
                return new ByteArrayInputStream(bytes);
            } else {
                logger.info("resource not found");
            }
        } 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 {
            InputStream in = CertificateManager.class.getClass().getResourceAsStream(keystore);
            KeyStore keyStore = KeyStore.getInstance(KeyStore.getDefaultType());
            keyStore.load(in, pass.toCharArray());
            logger.info("Keystore was created from resource file");
            return keyStore;
        } catch (Exception e) {
            logger.info("Fail to create keystore from resource file");
        }

        File file = new File(keystore);
        KeyStore keyStore = KeyStore.getInstance("JKS");
        if (file.exists()) {
            keyStore.load(new FileInputStream(file), pass.toCharArray());

    private void addCertificate(String certFileName, String certificateAlias) throws CertificateException,

        InputStream certStream = fullStream(certFileName);
        Certificate certs = cf.generateCertificate(certStream);
        myTrustStore.setCertificateEntry(certificateAlias, certs);

    }
    public X509TrustManager getMytrustManager() {
        return myTrustManager;
    }
    public void setMytrustManager(X509TrustManager myTrustManager) {
        this.myTrustManager = myTrustManager;
    }
}

如果需要，该类将创建密钥存储库，并能够在其中管理证书。下面是SSL context的类:

public class CustomTrustManager implements X509TrustManager {

    private final static Logger logger = Logger.getLogger(CertificateManager.class);

    private static SSLSocketFactory socketFactory;
    private static CustomTrustManager instance = new CustomTrustManager();
    private static List<CertificateManager> register = new ArrayList<>();

    public static CustomTrustManager getInstance() {
        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;
    }
}

这个类被设置为单例，因为只允许一个defaultSSL上下文。现在来看用法:

            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，它将无法与此设置，因为我将证书文件保存在资源文件夹内，所以我的路径不是绝对的。但总的来说，它工作得很完美。

它是对答案https://stackoverflow.com/a/36427118/1491414的补充。由于@MagGGG

请确保您有管理员权限 请使用双引号作为密钥存储库路径(-keystore C:\Program Files (x86)\Java\ jre1.6.0_22\lib\security\cacerts")，因为在Windows操作系统中，默认的安装位置将是程序文件，由于程序文件之间的空格，您将得到一个错误。

尝试复制java cacerts:

cp /usr/lib/jvm/java - 1.8.0 openjdk 1.8.0.172 b11.fc28——9.。除x86_64 / jre / lib /安全/ $ JAVA_HOME / jre / lib /安全/除

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

不管信任库中的certs如何，我都得到这个错误。对我来说，问题是在参数行上传递的属性的顺序。 当我把-Djavax.net.ssl.trustStore=& -Djavax.net.ssl.trustStorePassword=之前-Dspring.config。Location = & -jar args我能够通过https成功调用我的rest调用。

-Dmaven.wagon.http.ssl.insecure=true -Dmaven.wagon.http.ssl.allowall=true

用于跳过证书验证。

警告!

仅用于开发目的，这是不安全的!
