Unexpected error: java.security.InvalidAlgorithmParameterException

Unexpected error: java.security.InvalidAlgorithmParameterException

1. 异常信息

Unexpected error: java.security.InvalidAlgorithmParameterException: the trustAnchors parameter must be non-empty executing POST https://xxxx/v1/corp/createcorp] with root cause fegin

2. 自定义 Feign 客户端以忽略 HTTPS 证书验证

这个错误提示说明在执行 HTTPS 请求时，Java 虚拟机无法找到任何可信任的根证书来验证服务器的 SSL 证书。这通常发生在 SSL 握手阶段，当客户端尝试建立与服务器的安全连接时。

错误发生在执行 POST 请求到 https://xxx/v1/corp/createcorp，这很可能是一个调用服务（如果这是正确的服务地址）的API。

3. feign 配置

@FeignClient(name = "tt", url = "${cc.url}")
public interface TtClient {@PostMapping("/v1/corp/createcorp")JSONObject createcorp(@RequestBody JSONObject body);
}
