Scala Playframework 访问HTTPS网站证书错误解决方案

使用Playframework访问https网站报如下错误：

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

 Cause: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target

正确的解决方案如下：

1. Make sure you have added your Certificate to your trust-store like this:

keytool -import -trustcacerts -keystore {JAVA_HOME}/jre/lib/security/cacerts -noprompt -alias -file {CORRECT_PATH}/what_ever.crt

1. If still the problem exists, set the path directly by setting java parameters in your execution command line like this:

-Djavax.net.ssl.trustStore={JAVA_HOME}/jre/lib/security/cacerts
