问题描述
我正在使用restTemplate进行发布请求，但出现以下错误：无法找到请求目标的有效证书路径
ValueError

下面是我的方法

解决方法
在建立从客户端到服务器的https连接时。握手过程失败，因为客户端需要验证服务器证书。在客户端，您需要颁发者证书（Root CA）来验证服务器证书。大多数根证书是JDK中预先存在的。根证书默认情况下存储在称为cacerts的密钥库文件中。在此，服务器证书不是由证书颁发机构颁发的，并且服务器正在使用自签名证书或内部CA颁发的证书。您需要将根CA证书添加到java cacerts密钥存储中。
您可以通过在浏览器中访问服务器站点来轻松检索根CA证书。单击网址栏中的安全锁板，然后浏览证书选项。您需要使用复制选项导出根CA证书，并将证书文件保存在系统上。
转到存在证书的位置eg: C:\Program Files\Java\jdk1.8.0_121\jre\lib\security，然后打开命令提示符以执行以下命令。
keytool -import -alias -aliasName -file pathToRootCA.crt -keystore cacerts
