java - 信任库中的根证书是否足以建立连接？

标签 java ssl httpsurlconnection

信任库中的根证书是否足以与网站建立连接？如果是这样，只是为了测试，我已将 google 的根证书导入到我创建的新信任库中并指向该信任库。即便如此，我还是收到以下异常。 javax.net.ssl.SSLHandshakeException:sun.security.validator.ValidatorException:PKIX 路径构建失败:sun.security.provider.certpath.SunCertPathBuilderException:无法找到请求目标的有效证书路径

但是如果我尝试使用默认的 Java 信任库连接到谷歌，那么它工作正常。有人可以帮我吗？ TIA。

最佳答案

我刚刚尝试为 google.com 构建一个 https get 请求。已加载 GlobalSign 证书。 Google 的证书是由该 CA 签名的，因此 ssl 握手应该会通过。下面是我使用的代码，它有效。

    @Test
    public void callGoogleWithRootCA() throws IOException, KeyStoreException, CertificateException, NoSuchAlgorithmException, KeyManagementException {
        String trustStorePath = "keystores-for-unit-tests/truststore.jks";
        String trustStorePassword = "secret";

        KeyStore trustStore;

        try(InputStream keystoreInputStream = this.getClass().getClassLoader().getResourceAsStream(trustStorePath)) {
            if (isNull(keystoreInputStream)) {
                throw new RuntimeException(String.format("Could not find the keystore file with the given location %s", trustStorePath));
            }

            KeyStore keystore = KeyStore.getInstance(KeyStore.getDefaultType());
            keystore.load(keystoreInputStream, trustStorePassword.toCharArray());
            trustStore = keystore;
        }

        TrustManagerFactory trustManagerFactory = TrustManagerFactory.getInstance(TrustManagerFactory.getDefaultAlgorithm());
        trustManagerFactory.init(trustStore);

        SSLContext sslContext = SSLContext.getInstance("TLSv1.2");
        sslContext.init(null, trustManagerFactory.getTrustManagers(), null);

        HttpsURLConnection connection = (HttpsURLConnection) new URL("https://www.google.com").openConnection();
        connection.setSSLSocketFactory(sslContext.getSocketFactory());
        connection.setRequestMethod("GET");
        String responseBody = IOUtils.toString(connection.getInputStream(), StandardCharsets.UTF_8);
        int responseCode = connection.getResponseCode();

        assertThat(responseCode).isEqualTo(200);
    }

keystore 文件中的具体证书请看这里: root ca for google

我无法在此处上传 keystore 文件，但这是我用于将证书导入新 keystore 的 pem 文件:

回到您的问题，可能是您的 keystore 未加载。您能否验证您的 keystore 文件是否不为空？
