我正试图在我的项目中使用WSO2身份服务器，并试图学习基础知识，但每次尝试时，我都会在运行从这里克隆的应用程序时遇到此异常，我已将application.properties文件中的颁发者uri更改为以下内容：spring.security.oauth2.client.provider.wso2.issuer-uri=https://localhost:9443/oauth2/token我还将客户端id和客户端机密更改为我在WSO2管理控制台上生成的那些异常消息

使用SSO密钥斗篷，我设置了参数"要求SSL"；至"；没有"；。但只有在开发环境中，这才是一个解决方案。
由于这是SSL握手问题，请尝试将Identity server的证书添加到java cacert文件中。基本上，您需要将WSO2服务器的证书添加到java cacerts中。Bellow post[1]解释了如何将超级租户的证书添加到java cacerts中。
