ESB WSO2 - 使用 OAuth 基础安全令牌对 API 应用安全性

如何解决ESB WSO2 - 使用 OAuth 基础安全令牌对 API 应用安全性

我正在使用本指南为 WSO2 集成器上的 API 应用安全性：https://docs.wso2.com/display/EI660/Applying+Security+to+an+API+#ApplyingSecuritytoanAPI-UsinganOAuthbasesecuritytoken

我在身份服务器上创建了一个应用程序，并通过邮递员调用了 https://localhost:9443/oauth2/token 并获得了访问令牌。但是当我想在这个 url http://172.16.148.75:8281/weatherforecast 上调用我的 esb api 时，身份服务器集成器会抛出一个包含以下内容的异常：

我是dotnet开发者，对java不熟悉，所以不知道org.wso2.handler.SimpleOauthHandler为什么会出现这个异常。大家能不能帮我一个忙，帮我解决这个问题？
