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。
处理方案:
一、将目标程序的证书加入到本地项目的jre的证书库。
1、导出目标程序的域名证书。
2、进入jre安装目录的证书存放位置。
cd C:Program FilesJavajdk1.8.0_251jrelibsecurity
C:Program FilesJavajdk1.8.0_251jrelibsecurity
C:Program FilesJavajre1.8.0_251libsecurity
3、导入目标域名的证书到当前目录下,root用户
keytool -import -alias abc -keystore cacerts -file D://aaa.cer
4、查看证书
keytool -list -keystore cacerts -alias aaa
二、源程序请求时信任所有的目标程序证书。

Log.info("调用电商五要素接口请求报文:{}", JSON.toJSonString(requestbase)); //result = HttpClientUtil.doPostJson(url, JSON.toJSonString(requestbase), 10000); result = HttpClientUtil.doPost(url, JSON.toJSonString(requestbase)); Log.info("调用电商五要素接口返回报文:{}",result);
