[java] idea执行k8s api报错-SSLHandshakeException: should not be presented in certificate_request

0 解决方法

在jdk启动参数加上如下参数，修改ssl 客户端协议：

-Djdk.tls.client.protocols=TLSv1.2

1 错误详情及解决详解

本地java程序单元测试调用k8s相关https api发生报错SSLHandshakeException: should not be presented in certificate_request, 具体内容如下：

检索关键词should not be presented in certificate_reques~~删除线格式~~在stackoverflow得到解决办法：

https://stackoverflow.com/questions/61872520/spring-cloud-vault-error-nested-exception-is-javax-net-ssl-sslhandshakeexceptio

两种解决思路：

1、升级java版本；

2、添加启动参数，使用TLSv1.2协议：

-Djdk.tls.client.protocols=TLSv1.2
