证书异常:未找到与使用 OAuth2RestTemplate 而不是 RestTemplate 的本地主机匹配的名称

Question

我正在尝试使用 OAuth2RestTemplate 访问自签名证书以通过 HTTPS 检索令牌，但我仍然收到此错误：

javax.net.ssl.SSLHandshakeException： java.security.cert.CertificateException： 没有与本地主机匹配的名称 发现

这是我抛出错误的单元测试：

    public class OAuth2ClientTest {
    private static final Logger logger = LoggerFactory
            .getLogger(SecurityConfig.class);
    @Value("${oauth.resource:https://localhost:8443}")
    private String baseUrl;
    @Value("${oauth.token:https://localhost:8443/oauth/token}")
    private String tokenUrl;
    @Value("${oauth.resource.id:microservice-test}")
    private String resourceId;
    @Value("${oauth.resource.client.id:client1}")
    private String resourceClientId;
    @Value("${oauth.resource.client.secret:changit}")
    private String resourceClientSecret;

    @Test
    public void execute_post_to_tokenUrl()
            throws ClientProtocolException, IOException {
        OAuth2RestTemplate template = template();
        ResponseEntity<String> response = template.exchange(
                tokenUrl,
                HttpMethod.POST,
                null,
                String.class);
        assertThat(response.getStatusCode().value(), equalTo(200));
    }
    private OAuth2RestTemplate template(){
        ResourceOwnerPasswordResourceDetails resource = new ResourceOwnerPasswordResourceDetails();
        resource.setAccessTokenUri(tokenUrl);
        resource.setId(resourceId);
        resource.setClientId(resourceClientId);
        resource.setClientSecret(resourceClientSecret);
        resource.setGrantType("password");
        resource.setScope(Arrays.asList("openid"));
        resource.setUsername("[e-mail]");
        resource.setPassword("user1");
        OAuth2RestTemplate template = new OAuth2RestTemplate(resource);
        ClientHttpRequestFactory factory = template.getRequestFactory();
        template.setRequestFactory(requestFactory());
        return template;
    }
    private HttpComponentsClientHttpRequestFactory requestFactory(){
        CloseableHttpClient httpClient
                = HttpClients.custom()
                .setSSLHostnameVerifier(new NoopHostnameVerifier())
                .build();
        HttpComponentsClientHttpRequestFactory requestFactory
                = new HttpComponentsClientHttpRequestFactory();
        requestFactory.setHttpClient(httpClient);
        return requestFactory;
    }
}

当我使用非HTTPS连接时，OAuth2代码工作正常。只是不使用HTTPS

如果您希望TLS正常工作，则必须创建别名为"localhost"的证书。
另一种可能性是静态或在测试配置中设置它：

final HostnameVerifier defaultHostnameVerifier = javax.net.ssl.HttpsURLConnection.getDefaultHostnameVerifier ();
final HostnameVerifier localhostAcceptedHostnameVerifier = new javax.net.ssl.HostnameVerifier () {
   public boolean verify ( String hostname, javax.net.ssl.SSLSession sslSession ) {
        if ( hostname.equals ( "localhost" ) ) {
            return true;
        }
         return defaultHostnameVerifier.verify ( hostname, sslSession );
    }
};
javax.net.ssl.HttpsURLConnection.setDefaultHostnameVerifier ( localhostAcceptedHostnameVerifier );
