Google 表格 java sdk oAuth 几个小时后未经授权（spring 启动）

Question

我成功创建了一个 spring 引导服务类，以便在 google 张纸上书写，遵循 Java Quistart Tutorial for Sheets API

我的问题是授权没有更新，所以在第一次通过浏览器成功验证后，几个小时后我得到 401 unauthorized。 如何在不重新发布浏览器登录的情况下自动更新令牌？

下面的代码，在此先感谢

编辑：

解决了如下修改 GoogleAuthorizationCodeFlow 对象的构建问题：

GoogleAuthorizationCodeFlow flow = new GoogleAuthorizationCodeFlow.Builder(this.httpTransport, this.jsonFactory,
            clientSecrets, this.scopes).setDataStoreFactory(this.dataStoreFactory).setAccessType("offline")
                    .setApprovalPrompt("force")
                    .addRefreshListener(
                            new DataStoreCredentialRefreshListener(credentialUserId, this.dataStoreFactory))
                    .build();

有一个叫refresh token的概念，好像很符合你的需求。

你可以在这个问题中找到很好的描述：

编辑：根据您的评论，我发现 google 有 DataStoreCredentialRefreshListener

Access protected resources using the Credential. Expired access tokens are automatically refreshed using the refresh token, if applicable. Make sure to use DataStoreCredentialRefreshListener and set it for the credential using Credential.Builder.addRefreshListener(CredentialRefreshListener).

  static void addDataStoreCredentialRefreshListener(
      Credential.Builder credentialBuilder, String userId, DataStoreFactory dataStoreFactory)
      throws IOException {
    credentialBuilder.addRefreshListener(
        new DataStoreCredentialRefreshListener(userId, dataStoreFactory));
  }
