feignclient https接口调用报证书错误

问题

最近在使用 feignclient 过程中，和第三方通过https 协议交互的时候，报错如下：

通过以下方式解决了

感觉自己才疏学浅，菜鸟一枚。对于 feignclient 的底层实现和网络交互协议上暂无研究。仍旧停留在应用的使用的表象上，深感不安，后面会继续努力。此次先记录下问题。

HTTPS（SSL）证书下载及配置

SSL证书的下载（阿里云）

登录阿里云账号

我们可以任意选择一个，这里选择的是箭头位置上的

这样我们就可以直接购买了，然后在支付成功后绑定我们的ip地址就OK。

SSL证书的配置

下载之后我们解压之后

然后把这个文件上传到我们的服务器上，在tomcat下需要配置一下，修改server.xml文件添加如下配置即可
