Spring Security oauth2客户端-如何获取JWT令牌

我正在尝试使用spring-security-oauth2-client和spring-security-oauth2-jose针对Azure AD进行身份验证并获取JWT令牌。登录部分有效，但是我收到的令牌不是JWT。这是我的配置：

@Configuration
@EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter {

@Autowired
private OAuth2UserService<OidcUserRequest, OidcUser> oidcUserService;


@Override
protected void configure(HttpSecurity http) throws Exception {
    http
    .authorizeRequests()
    .anyRequest()
    .authenticated()
    .and()
    .oauth2Login()
    .loginPage("/oauth2/authorization/azure")
    .userInfoEndpoint()
    .oidcUserService(oidcUserService);
}

}

认证之后，我从安全上下文中检索令牌，如下所示：

OAuth2AuthenticationToken authentication = (OAuth2AuthenticationToken) 
SecurityContextHolder.getContext().getAuthentication();
OAuth2AccessToken accessToken = authorizedClientService.loadAuthorizedClient(
            authentication.getAuthorizedClientRegistrationId()
            ,authentication.getName()
            ).getAccessToken();

我得到一个Bearer令牌，看起来像：
