HttpClient请求https报ssl.SSLHandshakeException

javax.net.ssl.SSLHandshakeException: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target

这个问题是因为HttpClient请求https时需要ssl认证
解决方式有两种
一、正规途径，我们需要将证书导入到密钥库中
