Spring Boot Oauth 2 Okta证书问题

如何解决Spring Boot Oauth 2 Okta证书问题

我有一个简单的Spring boot应用程序在AWS Ec2的docker容器中运行。

使用以下配置将应用程序配置为使用oauth2针对Okta进行身份验证：

okta:
  oauth2:
    issuer: https://xxxx/oauth2/default
    clientId: xxxx
    clientSecret: xxxx

我收到以下错误

[invalid_token_response] An error occurred while attempting to retrieve the OAuth 2.0 Access Token Response: I/O error on POST request for "https://xxx/oauth2/default/v1/token": PKIX path building Failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target; nested exception is javax.net.ssl.SSLHandshakeException: PKIX path building Failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target

似乎Spring不信任Okta端点，我尝试将okta证书添加到Java cacerts文件中，但是没有运气。有什么想法吗？
