java - 在 Java 中禁用 SSL 证书验证

Question

如何在 java 8 中禁用证书验证。我正在尝试使用 https 连接到其他服务器，但我不断收到此错误:

Exception while providing content: [Thread[RMI TCP Connection(8)-192.168.56.1,5,RMI Runtime], 1549283885696] de.innovas.iaf.base_common.exceptions.NonRecoverableException: CT_0001_0[javax.xml.ws.soap.SOAPFaultException: Marshalling Error: com.sun.istack.SAXException2: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target

我尝试使用 -Dcom.sun.net.ssl.checkRevocation=false 修复它，我发现了 here .我还尝试使用 Java Keytool 将我自己的证书添加到池中。这两种想法都没有改变任何东西。问题可能是我用 openssl 生成了自己的证书。任何人都无法签署我导致的错误。

如果我可以仅出于测试目的而简单地禁用 SSL 检查，那就太好了。在生产场景中，我将拥有签名证书。

不建议禁用证书验证，除非它仅用于测试目的。您首先是如何调用该服务的？

如果您使用的是 Apache HttpClient:

SSLContext context = SSLContext.getInstance("TLSv1.2");
TrustManager[] trustManager = new TrustManager[] {
    new X509TrustManager() {
       public X509Certificate[] getAcceptedIssuers() {
           return new X509Certificate[0];
       }
       public void checkClientTrusted(X509Certificate[] certificate, String str) {}
       public void checkServerTrusted(X509Certificate[] certificate, String str) {}
    }
};
context.init(null, trustManager, new SecureRandom());

SSLConnectionSocketFactory socketFactory = new SSLConnectionSocketFactory(context,
        SSLConnectionSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER);

HttpClient client = HttpClientBuilder.create().setSSLSocketFactory(socketFactory).build();

如果您使用的是 HttpsURLConnection:

SSLContext context = SSLContext.getInstance("TLSv1.2");
TrustManager[] trustManager = new TrustManager[] {
    new X509TrustManager() {
       public X509Certificate[] getAcceptedIssuers() {
           return new X509Certificate[0];
       }
       public void checkClientTrusted(X509Certificate[] certificate, String str) {}
       public void checkServerTrusted(X509Certificate[] certificate, String str) {}
    }
};
context.init(null, trustManager, new SecureRandom());

HttpsURLConnection.setDefaultSSLSocketFactory(context.getSocketFactory());
