mvn PKIX path building failed: 进行中央库授权， unable to find valid certification path to requested target

解决方法： HTTP Status 500 - 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

之前就做邮件收发系统的时候，遇到了收取邮件授权的问题sun.security.validator.ValidatorException: PKIX path validation failed 使用这个可以处理 java -jar InstallCert.jar emailhost:port会生成证书，放在jre/lib/security就行
