PKIX路径验证失败：java.security.cert.CertPathValidatorException：签名检查失败

Question

来自Carlo Scarioni的Pro Spring Security书籍，我正在尝试将Spring Application与CAS Server集成。我按照书中指示的每一步，仍然坚持这个错误。请帮帮我。

Answer 1

如果cas服务器到cas客户端（jar文件将表现为客户端）没有发生通信，则会发生SSL握手异常。首先检查网络之间的事情，如两台服务器之间的通信，防火墙和端口阻塞，如果每件事都好的话这个问题是因为SSL证书，请确保在CAS服务器和客户端（Spring安全应用程序）应用程序中使用相同的证书。

Answer 2

我还没有发表评论，我只是延伸到@Kamal的答案。我正在学习同一本书，但我使用Tomcat作为一个区别，所以我无法给你相同的答案，因为我从未使用过Jetty： 正如他所说，您的SSL无法正常工作。您的浏览器和/或服务器不接受该证书，因此无法进行身份验证，因此SSL握手被拒绝。您需要确保已将证书CAS.crt添加到JVM cacerts中，正如他在书中所解释的那样（198-199），并检查它是否正确。然后，您需要使用您使用的密码将jetty-ssl.keystore添加到Jetty，以便它可以用于建立正确的连接。此外，您需要确定它已将本地主机写为cn名称，因为它不会起作用。这将根据您的环境（生产，测试，只是学习......）而改变，但这是使其按照书中描述的方式工作所必需的。 希望我在这里不要太离谱，但我希望它有所帮助。

Answer 3

我现在在Java 11中使用Spring 2.2.5

尝试将RestTemplate bean添加到Spring Application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();
}

然后，在与服务器通信的客户端类中，您必须添加bean RestTemplate restTemplate并将其传递给构造函数。

然后，在一种方法中，您必须像这样编写远程休息端点调用：

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

Answer 4

我已遇到此问题，发现SSL证书已过期。 用最新的证书替换过期的SSL证书后，问题已解决。
