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：
- 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
- 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
