PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to fin

摘要：java访问Https接口获取数据异常
异常： PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target

翻译： 无法找到到请求目标的有效认证路径
表象： 有些电脑环境可以运行，有些环境不能运行
原因： 使用环境为JDK, 而非OpenJDK导致报错。

报错使用的jar函数

环境调整如下图所示：

详细报错如下：
