项目构建成功，当我点击其余 URL 时，它将重定向到密钥隐藏页面进行身份验证。

员工休息控制器

@RestController
public class EmployeeRestController {

  @GetMapping(path = "/username")
  public String getAuthorizedUserName() {
    return "Username Returned";
  }

  @GetMapping(path = "/roles")
  public String getAuthorizedUserRoles() {
    return "Roles Returned";
  }
}

启动

@SpringBootApplication
public class Startup {

  public static void main(String[] args) {
    SpringApplication.run(Startup.class, args);
  }
}

我在使用 springboot-2.2.0/keycloak-7.0.1 时遇到了同样的问题。我将 bean KeycloakSpringBootConfigResolver 移动到另一个配置文件并且它可以工作。

@Configuration
public class BeanKeycloakConfiguration {
    @Bean
    public KeycloakSpringBootConfigResolver KeycloakConfigResolver() {
        return new KeycloakSpringBootConfigResolver();
    }
}`
