java - Google 身份验证找不到 .p12 文件

Question

我正在尝试制作一个可以编辑我的 Google 电子表格的应用程序。

但是我在身份验证部分遇到一些问题。 现在我的身份验证代码如下所示。

    URL SPREADSHEET_FEED_URL = new URL("https://spreadsheets.google.com/feeds/spreadsheets/private/full");

    File p12 = new File("./Key.p12");

    HttpTransport httpTransport = new NetHttpTransport();
    JacksonFactory jsonFactory = new JacksonFactory();
    String [] SCOPESArray = {"https://spreadsheets.google.com/feeds","https://spreadsheets.google.com/feeds/spreadsheets/private/full"};
    final List SCOPES = Arrays.asList(SCOPESArray);


    GoogleCredential credential = new GoogleCredential.Builder()
                .setTransport(httpTransport)
                .setJsonFactory(jsonFactory)
                .setServiceAccountId("XXXXXXXXXXXXXgserviceaccount.com")
                .setServiceAccountScopes(SCOPES)
                .setServiceAccountPrivateKeyFromP12File(p12)
                .build();

但是当我尝试运行此应用程序时，该应用程序在 Google 凭据生成器上崩溃。这是我收到的错误:

我尝试了不同的 p12 文件路径，但都不起作用。我尝试了“./Key.p12”、“/Key.p12”、“Key.p12”以及文件的完整路径，但这也不起作用。

它说它无法打开它，但我已将它放在项目目录中，如“Projectname/Key.p12”。我不知道我做错了什么，如果有人能帮助我那就太好了。

尝试像这样创建 p12 File 对象:

File p12 = new File(this.getClass().getResource("/Key.p12").toURI());
