SunCertPathBuilderException: unable to find valid certification path to requested target
背景：
使用HttpClient4.5发送post请求，对方需要使用证书，需要本地安装证书，之后本地正常请求https，部署到centos后，安装证书，发送http请求报错：
SunCertPathBuilderException: unable to find valid certification path to requested target
证书安装：
keytool -import -v -trustcacerts -alias spdbuat -file spdbuat.cer -storepass changeit -keystore E:/soft/java8/jre/lib/security/cacerts查找证书alias名为spdbuat:
keytool -list -v -keystore E:/soft/java8/jre/lib/security/cacerts -storepass changeit -alias spdbuat本地证书安装后，一起正常，服务器安装证书后，运行出现如下错误:
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
