我设法在ReactJS中执行了单点登录，并能够检索到一个JWT令牌。现在我想使用该令牌调用我的Sping Boot 后端，但this tutorial验证令牌的方式似乎由于某种原因不起作用，我得到了401 Unauthorized。
我的代码现在是如何工作的。
简单控制器：

@AllArgsConstructor
@RequestMapping(path = "employee")
@RestController
public class EmployeeController {
    @GetMapping("/get")
    public String givePotato(){
        return "potato achieved";
    }
}

安全配置：如果我没记错的话，基本上就是说它需要授权那些通过资源服务器身份验证的请求。

@Configuration
public class SecurityConfig {
    @Bean
    public SecurityFilterChain filterChain(HttpSecurity http) throws Exception {
        http.cors()
                .and()
                .authorizeRequests().anyRequest().authenticated()
                .and()
                .oauth2ResourceServer().jwt();

        return http.build();
    }
}

应用道具：仅使用资源服务器来检查验证

spring.security.oauth2.resourceserver.jwt.issuer-uri=https://login.microsoftonline.com/<<<mytenantID>>>/oauth2/v2.0/token

接下来，我尝试通过Postman进行一个get-调用，调用头文件为Authorization = Bearer {jwt_token}，这又会产生下面的一堆错误：

有Spring和Azure AD知识的人知道我做错了什么吗？
我也试过这个github教程，但是它只返回HTML，告诉我需要登录。
