No subject alternative names matching IP address xxxxxx found

背景：RestTemplate.getForEntity方法 http请求 8443接口(日志里变成https)，报错

日志报错：
I/O error on GET request for \"https://xxxxxxxxxx\": java.security.cert.CertificateException: No subject alternative names matching IP address xxxxxx found;
nested exception is javax.net.ssl.SSLHandshakeException: java.security.cert.CertificateException: No subject alternative names matching IP address xxxxxx found
采用如下方法解决（可以添加证书或者跳过验证，我采用跳过的方式）

再请求报400
RestTemplate将http请求修改为https
再测试就OK了
