我创建了一个要部署在应用程序服务器中的 Spring Boot Web 项目 (.war)。我想将 keycloak sso 与 spring security 集成。到 keycloak 登录页面的重定向工作正常。但之后它会在浏览器中抛出错误。
浏览器中抛出的错误
There was an unexpected error (type=Internal Server Error, status=500). Current user principal is not of type [org.keycloak.KeycloakPrincipal]: org.keycloak.adapters.springsecurity.token.KeycloakAuthenticationToken@450ca8a1: Principal: da02ad1b-32c1-4dde-a6f4-b56a06d7dc2e; Credentials: [PROTECTED]; Authenticated: true; Details: org.keycloak.adapters.springsecurity.account.SimpleKeycloakAccount@20e00226; Not granted any authorities
应用程序服务器控制台出错

最佳答案
exception [Current user principal is not of type [org.keycloak.KeycloakPrincipal]
您应该使用KeycloakAuthenticationToken而不是KeycloakPrincipal
关于java.lang.IllegalStateException :Current user principal is not of type when i try to integrate keycloak with spring boot web + spring security project，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/58817175/
