Spring security PKIX路径验证失败：java.security.cert.CertPathValidator异常：签名检查失败

从卡洛·斯卡里奥尼（Carlo Scarioni）的Pro-Spring安全书籍中，我尝试将Spring应用程序与CAS服务器集成。我按照书中指示的每一步去做，但我仍然被这个错误所困扰。请帮帮我

如果没有发生cas服务器到cas客户端（jar文件将作为客户端）的通信，则会发生SSL握手异常，首先检查网络情况，如两台服务器之间的通信、防火墙和端口阻塞，如果一切正常，则此问题是因为SSL证书，请确保在CAS服务器和客户端（Spring security app）应用程序中使用相同的证书。

由于我还不能发表评论，我将继续讨论@Kamal的答案。我是通过同一本书学习的，但我使用Tomcat作为区别，因此我无法给出与我从未使用Jetty相同的答案： 正如他所说的，您的SSL没有正常工作。您的浏览器和/或服务器不接受该证书，因此它无法进行身份验证，因此SSL握手被拒绝。正如他在书（198-199）中解释的那样，您需要确保已将证书

CAS.crt

添加到JVM cacerts中，并检查它是否正确。然后，您需要将

jetty ssl.keystore

添加到jetty，并使用您使用的密码，以便使用它建立正确的连接。另外，您需要肯定地确认它是以cn名称编写的localhost，否则它将无法工作。这取决于您的环境（生产、测试、只是学习…），但这是使其如本书所述工作所必需的。

希望我在这里不是太离谱，但我希望这有帮助。

我遇到了这个问题，发现SSL证书已过期。

用最新的证书替换过期的SSL证书后，问题得到解决。

我现在将Spring 2.2.5与Java 11一起使用

尝试将RESTTemplatebean添加到Spring应用程序上下文中，以便接受所有证书，如下所示：

@Bean
public RestTemplate restTemplate(RestTemplateBuilder builder) throws NoSuchAlgorithmException, KeyManagementException {
    TrustManager[] trustAllCerts = new TrustManager[]{
            new X509TrustManager() {
                public java.security.cert.X509Certificate[] getAcceptedIssuers() {
                    return new X509Certificate[0];
                }

                public void checkClientTrusted(
                        java.security.cert.X509Certificate[] certs, String authType) {
                }

                public void checkServerTrusted(
                        java.security.cert.X509Certificate[] certs, String authType) {
                }
            }
    };
    SSLContext sslContext = SSLContext.getInstance("SSL");
    sslContext.init(null, trustAllCerts, new java.security.SecureRandom());
    CloseableHttpClient httpClient = HttpClients.custom()
            .setSSLContext(sslContext)
            .setSSLHostnameVerifier(NoopHostnameVerifier.INSTANCE)
            .build();
    HttpComponentsClientHttpRequestFactory customRequestFactory = new HttpComponentsClientHttpRequestFactory();
    customRequestFactory.setHttpClient(httpClient);
    return builder.requestFactory(() -> customRequestFactory).build();
}

private YourSpecificResponseJSONClass getYourRemoteResponse() {
    YourSpecificResponseJSONClass ret = getYourDefaultJSONResponseInCaseOfAnyException();
    try {
        ret = restTemplate.getForObject("<yourRemoteURL>", YourSpecificResponseJSONClass.class);
    } catch (Throwable t) {
       //log whatever
    }
    return ret;
}

然后，在与服务器通信的客户机类中，必须添加bean

restemplate restemplate

，并将其传递给构造函数

然后，在方法中，必须像这样编写远程rest端点调用：

@Bean
public RestTemplate restTemplate(RestTemplateBuilder builder) throws NoSuchAlgorithmException, KeyManagementException {
    TrustManager[] trustAllCerts = new TrustManager[]{
            new X509TrustManager() {
                public java.security.cert.X509Certificate[] getAcceptedIssuers() {
                    return new X509Certificate[0];
                }

                public void checkClientTrusted(
                        java.security.cert.X509Certificate[] certs, String authType) {
                }

                public void checkServerTrusted(
                        java.security.cert.X509Certificate[] certs, String authType) {
                }
            }
    };
    SSLContext sslContext = SSLContext.getInstance("SSL");
    sslContext.init(null, trustAllCerts, new java.security.SecureRandom());
    CloseableHttpClient httpClient = HttpClients.custom()
            .setSSLContext(sslContext)
            .setSSLHostnameVerifier(NoopHostnameVerifier.INSTANCE)
            .build();
    HttpComponentsClientHttpRequestFactory customRequestFactory = new HttpComponentsClientHttpRequestFactory();
    customRequestFactory.setHttpClient(httpClient);
    return builder.requestFactory(() -> customRequestFactory).build();
}

private YourSpecificResponseJSONClass getYourRemoteResponse() {
    YourSpecificResponseJSONClass ret = getYourDefaultJSONResponseInCaseOfAnyException();
    try {
        ret = restTemplate.getForObject("<yourRemoteURL>", YourSpecificResponseJSONClass.class);
    } catch (Throwable t) {
       //log whatever
    }
    return ret;
}

private YourSpecificResponseJSONClass getYourRemoteResponse（）{
YourSpecificResponseJSONClass ret=GetYourDefaultJsonResponseInCaseofAyeException（）；
试一试{
ret=restemplate.getForObject（“，YourSpecificResponseJSONClass.class”）；
}捕获（可丢弃的t）{
//记录什么
}
返回ret；
}

如果您只接受任何证书，那么它不会为您提供任何保护！
