Java SpringBoot Rest OAuth2 Principal 为空

Question

我尝试了有关Java SpringBoot REST OAuth2 身份验证的不同教程。我尝试将它们与简单的 Web 表单身份验证结合起来，但我仍然无法获得 Principal 类对象。我null每次都在我的休息控制器上（显示在下面的行中），我错过了什么吗？

授权服务器配置.java

import org.springframework.beans.factory.annotation.Autowired;

import org.springframework.context.annotation.Configuration;

import org.springframework.security.authentication.AuthenticationManager;

                .authorizedGrantTypes("password", "authorization_code", "refresh_token", "implicit")

                .scopes("read", "write", "trust")

                .secret("secret")

                .accessTokenValiditySeconds(120).//Access token is only valid for 2 minutes.

                refreshTokenValiditySeconds(600);//Refresh token is only valid for 10 minutes.

    }

    @Override

    public void configure(AuthorizationServerEndpointsConfigurer endpoints) {

        endpoints.tokenStore(tokenStore).authenticationManager(authenticationManager);

    }

}
