RestTemplate 中的 CertificateParsingException - pem 证书

Question

我的 pem 证书有问题。我正在尝试从具有证书授权的其他服务器调用服务。

@Override
public void changeAnalitycsState(Device device) {

    SSLContext context = null;

    Security.addProvider(new BouncyCastleProvider());

    context = SSLContexts.custom()
            .loadTrustMaterial(null, new TrustSelfSignedStrategy())
            .useProtocol("TLS").build();

    byte[] certificate = getCertificate();

    byte[] certBytes = parseDERFromPEM(certificate,
            "-----BEGIN CERTIFICATE-----", "-----END CERTIFICATE-----");

    X509Certificate cert = generateCertificateFromDER(certBytes);

    KeyStore keystore = KeyStore.getInstance("JKS");
    keystore.load(null);
    keystore.setCertificateEntry("cert-alias", cert);

    KeyManagerFactory kmf = KeyManagerFactory.getInstance("SunX509");
    kmf.init(keystore, "changeit".toCharArray());

    KeyManager[] km = kmf.getKeyManagers();

    context.init(km, null, null);

    @SuppressWarnings("deprecation")
    HttpClient httpClient =  HttpClientBuilder.create().setSslcontext(context)
            .setSSLSocketFactory(new SSLConnectionSocketFactory(context.getSocketFactory(), new AllowAllHostnameVerifier()))
            .build();

    ClientHttpRequestFactory httpClientRequestFactory = new HttpComponentsClientHttpRequestFactory(httpClient);

    String plainCreds = "user:pass";
    byte[] plainCredsBytes = plainCreds.getBytes();
    byte[] base64CredsBytes = Base64.encodeBase64(plainCredsBytes);
    String base64Creds = new String(base64CredsBytes);

    RestTemplate restTemplate = new RestTemplate(httpClientRequestFactory);

    HttpHeaders httpHeaders = new HttpHeaders();
    httpHeaders.add(HttpHeaders.AUTHORIZATION, "Basic " + base64Creds);
    httpHeaders.setContentType(MediaType.APPLICATION_JSON);

    HttpEntity<Device> entity = new HttpEntity<Device>(
            device, httpHeaders);
    restTemplate
            .exchange("https://xxx:8666/yyy/", HttpMethod.POST, entity, Void.class);

}

private byte[] parseDERFromPEM(byte[] pem, String beginDelimiter,
        String endDelimiter) {
    String data = new String(pem);
    String[] tokens = data.split(beginDelimiter);
    tokens = tokens[1].split(endDelimiter);
    return DatatypeConverter.parseBase64Binary(tokens[0]);
}

private X509Certificate generateCertificateFromDER(byte[] certBytes) {
    CertificateFactory factory;
    X509Certificate cert = null;
    factory = CertificateFactory.getInstance("X.509");
    cert = (X509Certificate) factory
    .generateCertificate(new ByteArrayInputStream(certBytes));

    return cert;
}

错误是：

我已经尝试过这个解决方案：RestTemplate with pem certificate，但它对我不起作用。 getCertificate() 方法返回 byte[] 中的证书（我有一个返回证书的服务。我知道，这是个坏主意，但这就是它的工作原理）。

这是我第一次接触证书。 我该如何解决？

尝试将此代码添加到方法的开头。如果是这样，请将代码移动到应用程序的开头：

java.lang.System.setProperty("javax.net.ssl.trustStore", "NONE");
