Java HttpClient在执行GET to https url时引发SSLHandshakeException

我正在运行一个小main（在Java8中，版本1.8.0.112）来尝试并执行对“https”url的HTTP请求，我们称之为“原始url”。我使用的是标准CloseableHttpClient，创建方式如下：

CloseableHttpClient httpClient = HttpClientBuilder.create()
            .setConnectionManager(new PoolingHttpClientConnectionManager())
            .setDefaultRequestConfig(RequestConfig.DEFAULT)
            .build();

但当我击中：

httpClient.execute(request);

我得到了这个错误：

javax.net.ssl.SSLHandshakeException: Received fatal alert: handshake_failure

（下面是完整的堆栈跟踪）

奇怪的是，当我从同一个java代码中访问不同的“https”URL时，它工作得很好。此外，当我从Chrome或Postman（REST客户端）到达“原始url”时，我成功地到达了它。我还尝试从php代码执行对“原始url”的http调用，效果很好

我在StackOverflow中寻找了许多答案，都试图将HttpClient设置为忽略未知证书，但没有成功。此外，由于我可以通过Chrome/Postman/php代码访问“original_url”站点，所以该站点的证书似乎没有过期

JVM密钥库可能有问题吗？任何帮助都将不胜感激

握手错误可能有很多不同的方面，但几乎与服务器证书验证无关，这意味着禁用验证将无济于事。可能没有共享密码、没有公共协议版本、缺少客户端证书等，但从提供的信息来看这是未知的。如果这是一个可公开访问的站点，我建议将URL添加到您的问题中。添加此

-Djavax.net.debug=ssl
