spring-boot - Spring SAML 中的 SSL 对等方主机名验证失败

Question

我正在尝试将我的 Spring Boot 项目配置为针对第三方 IDP 使用 SAML 身份验证。我已经实现了从 vdenotaris 进行配置与 SSOCircle 提供商合作，现在我想将其切换到其他提供商。

SAML 元数据端点启用了 HTTPS，并且我已经创建了一个 keystore ，其中包含元数据中给出的证书(用于签名和加密)和 HTTP 端点提供的证书(基于 this answer)。然后，我将它们保存在证书文件 ($CERTIFICATE_FILE) 中，并使用此脚本生成我的 keystore :

keytool -delete -alias third-party -keystore $KEYSTORE_FILE -storepass $KEYSTORE_PASSWORD
keytool -import -alias third-party -file $CERTIFICATE_FILE -keystore $KEYSTORE_FILE -storepass $KEYSTORE_PASSWORD -noprompt
keytool -genkeypair -alias mycompany -keypass mycompanypass -keystore $KEYSTORE_FILE

然后，当使用此 keystore 检索 SAML 元数据时，我收到此错误:

这些是我基于 vdenotaris 链接项目的配置的相关部分:

// Setup TLS Socket Factory
@Bean
public TLSProtocolConfigurer tlsProtocolConfigurer() {
    return new TLSProtocolConfigurer();
}

@Bean
public ProtocolSocketFactory socketFactory() {
    return new TLSProtocolSocketFactory(keyManager(), null, "allowAll");
}

@Bean
public Protocol socketFactoryProtocol() {
    return new Protocol("https", socketFactory(), 443);
}

@Bean
public MethodInvokingFactoryBean socketFactoryInitialization() {
    MethodInvokingFactoryBean methodInvokingFactoryBean = new MethodInvokingFactoryBean();
    methodInvokingFactoryBean.setTargetClass(Protocol.class);
    methodInvokingFactoryBean.setTargetMethod("registerProtocol");
    Object[] args = { "https", socketFactoryProtocol() };
    methodInvokingFactoryBean.setArguments(args);
    return methodInvokingFactoryBean;
}

// Central storage of cryptographic keys
@Bean
public KeyManager keyManager() {
    DefaultResourceLoader loader = new DefaultResourceLoader();
    Resource storeFile = loader.getResource("classpath:/saml/mySamlKeystore.jks");
    String storePass = "storepass";
    Map<String, String> passwords = new HashMap<String, String>();
    passwords.put("mycompany", "mycompanypass");
    String defaultKey = "mycompany";
    return new JKSKeyManager(storeFile, storePass, passwords, defaultKey);
}

但是，在这里我发现了一些误解。据我所知， TLSProtocolConfigurer创建一个 TLSProtocolSocketFactory本身，为什么示例项目会同时创建两个 bean？根据 docs使用 TLSProtocolConfigurer应该够了，但是如何创建 socketFactoryProtocol() ?

我会很感激这里有一些光。

只需删除 TLSProtocolConfigurer bean 并将元数据信任检查设置为 false
