无法找到请求目标的有效证书路径-密钥斗篷-Springboot-自签名证书-测试

Question

我在Spring Boot应用程序中进行了集成测试，有些测试需要从Keycloak获取令牌。每次通信都是通过带有自签名证书的SSL进行的。

启动这些测试时，我遇到了异常：

SunCertPathBuilderException: unable to find valid certification path to requested target

问题似乎类似于Accept server's self-signed ssl certificate in Java client，但该解决方案对我不起作用。

这是我获得令牌的地方：

private AccessTokenResponse getToken() throws GeneralSecurityException {        
        Keycloak keycloak = Keycloak.getInstance(keycloakAuthServerUrl, keycloakRealm, 
            login, password, keycloakResource, keycloakCredentialsSecret);
        return keycloak.tokenManager().getAccessToken();
    }

Answer 1

根据Accept server's self-signed ssl certificate in Java client中的建议，创建一个自定义信任管理器：

import javax.net.ssl.X509TrustManager;

public class TestTrustManager implements X509TrustManager {

        @Override
        public java.security.cert.X509Certificate[] getAcceptedIssuers() {
            return new java.security.cert.X509Certificate[0];
        }
        @Override
        public void checkClientTrusted(java.security.cert.X509Certificate[] certs, String authType) {
        }
        @Override
        public void checkServerTrusted(java.security.cert.X509Certificate[] certs, String authType) {
        }
}

然后将其添加到密钥库“构造函数”中：

private AccessTokenResponse getToken() throws GeneralSecurityException {
        // Install the all-trusting trust manager
        SSLContext sslContext = SSLContext.getInstance("SSL");
        sslContext.init(null, new TrustManager[] { new TestTrustManager() }, new java.security.SecureRandom());

        Keycloak keycloak = Keycloak.getInstance(keycloakAuthServerUrl, keycloakRealm, 
            login, password, keycloakResource, keycloakCredentialsSecret, sslContext); // <--- !!! ADD IT HERE !!!
        return keycloak.tokenManager().getAccessToken();
    }
