sun.security.provider.certpath.SunCertPathBuilderException:无法找到请求目标的有效认证路径

我有一个类，将从https服务器下载文件。当我运行它时，它返回了很多错误。我的证书好像有问题。是否可以忽略客户机-服务器身份验证?如果有，怎么做?

AVG版本18.1.3044 (Windows 10)干扰我的本地Spring应用程序。

解决方法:在AVG的“网页和邮件”部分输入，关闭“邮件保护”。 如果站点不安全，AVG会阻止证书。

我在赛门铁克的有效签名通配符证书上也遇到了同样的问题。

首先尝试使用-Djavax.net.debug=SSL运行java应用程序，看看到底发生了什么。

我最终导入了导致证书链中断的中间证书。

我从赛门铁克下载了缺少的中间证书(您可以在ssl握手日志中看到缺少证书的下载链接:在我的例子中是http://svrintl-g3-aia.verisign.com/SVRIntlG3.cer)。

我在java密钥库中导入了证书。导入中间证书后，我的通配符ssl证书终于开始工作:

keytool -import -keystore ../jre/lib/security/cacerts -trustcacerts -alias "VeriSign Class 3 International Server CA - G3" -file /pathto/SVRIntlG3.cer

仅适用于Windows，请遵循以下步骤:

In Chrome go to settings. In Settings click show advance settings. Under HTTPS/SSL Click on Manage Certificates. Export Your Certificate. In Windows searchs (Pressing windows key on keyboard) type java. Select (Configure Java) Option Which will open Java Control Panel Select Security tab in Java Control Panel Select Manage Certificates Click Import Under (User) tab selected and certificate type as (Trusted Certificates) Click import button and browse to downloaded certificate and import it.

就像最初的问题一样——如何忽略证书错误，这里为那些使用SpringBoot和RestTemplate的人提供了解决方案

@Service
public class SomeService {

    private final RestTemplate restTemplate;

    private final ObjectMapper objectMapper;    

    private static HttpComponentsClientHttpRequestFactory createRequestFactory() {
        try {
            SSLContextBuilder sslContext = new SSLContextBuilder();
            sslContext.loadTrustMaterial(null, new TrustAllStrategy());
            CloseableHttpClient client = HttpClients.custom().setSSLContext(sslContext.build()).setSSLHostnameVerifier(NoopHostnameVerifier.INSTANCE).build();
            HttpComponentsClientHttpRequestFactory requestFactory = new HttpComponentsClientHttpRequestFactory();
            requestFactory.setHttpClient(client);
            return requestFactory;
        } catch (KeyManagementException | KeyStoreException | NoSuchAlgorithmException var3) {
            throw new IllegalStateException("Couldn't create HTTP Request factory ignore SSL cert validity: ", var3);
        }
    }

    @Autowired
    public SomeService(RestTemplate restTemplate, ObjectMapper objectMapper) {
        this.objectMapper = objectMapper;
        this.dimetorURL = dimetorURL;
        restTemplate.setRequestFactory(createRequestFactory());
    }


    public ResponseEntity<ResponseObject> sendRequest(RequestObject requestObject) {
        //...
        return restTemplate.exchange(url, HttpMethod.GET, ResponseObject.class);
        //...
    }
}

在我的例子中，我的密钥存储库和信任存储库都具有相同的证书，因此删除信任存储库有帮助。有时，如果您有多个证书副本，则证书链可能会成为问题。

使用Firefox浏览器导出SSL证书。您可以通过在浏览器中点击URL，然后选择导出证书的选项来导出它。让我们假设证书文件名是your.ssl.server.name.crt 进入JRE_HOME/bin或JDK/JRE/bin目录 输入命令 Keytool -keystore ..\lib\security\cacerts -import -alias your.ssl.server.name -file .\relative-path-to-cert-file\your.ssl.server.name.crt 重新启动Java进程
