我想从Java代码中以https开头的URL，所以我已将该站点的信任证书添加到我的Java KeyStore中，但是仍然低于错误...
Exception in thread "main" 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
添加证书后是否还需要进行任何更改？
