为了在我的代码中实现类似的功能，我将遵循Baeldung https://www.baeldung.com/spring-boot-keycloak的示例。
但是，仅通过JWT访问是行不通的，它只能通过登录屏幕进行访问。
在代码示例中，而不是在我的代码中，只需克隆repo，获取keycloak服务器并运行它，当尝试访问http://localhost:8081/customers时，一切都按计划工作
应用程序将重定向到keycloak登录，我输入凭据，API将返回数据，如下图所示

所以这个例子完全有效。
但是，当 Postman 成功获取令牌时，如下所示，我无法通过输入令牌作为身份验证载体来访问 Postman 的资源。

应用程序仍会将我重定向到登录keycloak屏幕

1.为什么会发生这种情况？
1.如何才能通过登录屏幕和JWT标记来获得这两种方式的访问权限？
应用程序的调试日志包括

我试过用grant_type到client_credentials，password来玩，但是没有任何效果。我也试过注解掉http.oauth2Login()。仍然没有运气
通过extends KeycloakWebSecurityConfigurerAdapter的其他示例并将keycloak安全性作为适配器来应用，实际上行为更好，访问是两种方式都可能的。
