javax.net.ssl.SSLHandshakeException: sun.security.validator.ValidatorException: PKIX path building

摘要: linux tomcat

最近调用单点登录系统报错如下：

java.lang.RuntimeException: 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

原因是需要把请求地址的证书引入进来，从浏览器里地址栏左边的锁把证书下载下来，然后需要导入到linux的服务器上。
查看证书的命令为：

keytool -list -keystore /usr/local/jdk1.8.0_112/jre/lib/security/cacerts/

导入证书的命令为：

keytool -import -alias LL1 -keystore /usr/local/jdk1.8.0_112/jre/lib/security/cacerts/ -file /usr/local/jdk1.8.0_112/jre/lib/security/hnagroup.cer

重启服务器即可解决掉此异常。
