如何使用 Java 在 https 连接请求中附加 .pfx 证书？

Question

我有一个安装在 Windows 证书存储中的 pfx 证书，我可以使用 C# 将其附加到 https rest 调用中。

现在我需要使用 Java 做同样的事情。我读到 .pfx 证书有私钥以及一个或多个证书。

我收到以下错误：PKIX 路径构建失败：sun.security.provider.certpath.SunCertPathBuilderException：无法找到请求目标的有效证书路径。

我在 Java

中尝试过的事情

我直接使用 KeyStore ks = KeyStore.getInstance("Windows-MY", "SunMSCAPI") 从 Windows 商店获取证书并创建了一个 SSLContext我在 HTTPS 调用中使用的
我从 Windows 存储中导入证书作为 .cer 文件并从代码中读取它作为文件并将其附加到 https 调用
我从代码中读取了 .pfx 文件并将其附加到调用中。
我已将证书添加到 Java-Home (C:/Work/certi/jre1.8.0_91/lib/security/cacerts) 的 cacerts 文件中，使用KeyTool.

假设您已将 Issuing CA Cert（参见下面的评论）导入到 cacerts 文件，以下内容应该有效，可以在不同的 SO 线程中找到很多帮助 Here:
