各位大佬好，我现在在做Spring Boot集成Google OAuth2的功能，想要获取用户的邮箱信息，但遇到了一个报错，卡了好一会儿了，特来求助！

报错信息

当执行到获取用户信息的代码时，抛出了如下错误：

{"errors":["OAuth2Credentials instance does not support refreshing the access token. An instance with a new access token should be used, or a derived type that supports refreshing."]}

问题代码

我的回调接口代码如下，报错具体出现在Userinfo userinfo = oauth2.userinfo().get().execute();这一行：

@GetMapping("/callback")
public ResponseEntity<String> callback(@RequestParam(value = "code") String code) throws IOException {

    TokenResponse tokenResponse = authService.getTokenResponse(code, CALLBACK_URI);

    List<String> scopes = List.of("https://www.googleapis.com/auth/userinfo.email");

    GoogleCredentials credentials = GoogleCredentials.create(new AccessToken(tokenResponse.getAccessToken(), null));

    GoogleCredentials scopedCredential = credentials.createScoped(scopes);

    HttpRequestInitializer initializer = new HttpCredentialsAdapter(scopedCredential);

    Oauth2 oauth2 = new Oauth2.Builder(httpTransport, jacksonFactory, initializer)
        .setApplicationName("Test") // 替换为你的应用名称
        .build();

    Userinfo userinfo = oauth2.userinfo().get().execute(); // 此处报错

    String email = userinfo.getEmail();
    System.out.println(email);

    return ResponseEntity.status(HttpStatus.OK).build();
}
