Java netflix zuul与microservice之间的证书认证

我已在我的应用程序netflix zuul中配置了调用其他服务，并且有必要在应用程序中包含一个证书

我正在尝试做与中相同的事情（使用带有证书的netflix zuul），但我遇到了问题

例如，在中表示使用了.keystore，但我拥有的文件是.cer和.key，我不知道如何将证书应用于我拥有的文件

你能帮我把我的证书和我的应用程序的netflix zuul代理连接起来吗

非常感谢大家

编辑->我已经尝试了解决方案，我的代码：

@Bean
    public CloseableHttpClient httpClient() throws Throwable {

    InputStream is = new FileInputStream(KEYSTOREPATH);
    //KEYSTOREPATH =    String KEYSTOREPATH = "E:/ARC/myapp/src/main/java/com/myapp/services/myapp/myapp.cer";

    // You could get a resource as a stream instead.

    CertificateFactory cf = CertificateFactory.getInstance("X.509");
    X509Certificate caCert = (X509Certificate)cf.generateCertificate(is);

    TrustManagerFactory tmf = TrustManagerFactory
        .getInstance(TrustManagerFactory.getDefaultAlgorithm());
    KeyStore ks = KeyStore.getInstance(KeyStore.getDefaultType());
    ks.load(null); // You don't need the KeyStore instance to come from a file.
    ks.setCertificateEntry("caCert", caCert);

    tmf.init(ks);

    SSLContext sslContext = SSLContext.getInstance("TLS");
    sslContext.init(null, tmf.getTrustManagers(), null);

  return HttpClients.custom().setSSLContext(sslContext).build();

}

当执行netflix zuul中配置的路径时，我得到以下错误：

Caused by: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target

您可以尝试构建SSLContext并信任.cer文件中的证书，如下所述：

贾维尔，我能够构建SSLContext，如下所示。你还有这个问题吗

 @Test
public void sslContext() {
    Class demoClass = Demo.class;
    InputStream is  = demoClass.getResourceAsStream("/test.cert");
    try {
        CertificateFactory cf = CertificateFactory.getInstance("X.509");
        X509Certificate caCert = (X509Certificate) cf.generateCertificate(is);
        TrustManagerFactory tmf = TrustManagerFactory
                .getInstance(TrustManagerFactory.getDefaultAlgorithm());
        KeyStore ks = KeyStore.getInstance(KeyStore.getDefaultType());
        ks.load(null); // You don't need the KeyStore instance to come from a file.
        ks.setCertificateEntry("caCert", caCert);
        tmf.init(ks);
        SSLContext sslContext = SSLContext.getInstance("TLS");
        sslContext.init(null, tmf.getTrustManagers(), null);
    } catch (CertificateException | NoSuchAlgorithmException | KeyStoreException | IOException | KeyManagementException e) {
        e.printStackTrace();
    }
}

非常感谢Mohit的回答，我已经尝试了他们在您告诉我的链接中添加的内容，当您启动应用程序并调用netflix zuul服务时，我收到一个错误，您无法找到证书：原因：sun.security.provider.certpath.SunCertPathBuilderException:无法找到请求目标的有效证书路径
