Question

我的应用程序（在glassfish上运行）访问谷歌电子表格以检索某些信息，我使用 google-api-client执行OAuth并获取对电子表格的访问权限。

有关OAuth和Spreadsheet API的更多详细信息，请访问： https://developers.google.com/identity/protocols/OAuth2ServiceAccount

以下是获取AuthenticatedService

的代码片段

    public SpreadsheetService getAuthenticatedService() {

            SpreadsheetService service =
                    new SpreadsheetService("MySpreadsheetIntegration-v1");

            try {

                //Generating a token every time, for the current requirements this is fine.
                JsonFactory JSON_FACTORY = JacksonFactory.getDefaultInstance();
                HttpTransport httpTransport = GoogleNetHttpTransport.newTrustedTransport();
                String filePath = RW_SW_P_12_KEY;
                String keyFilePath = new File(this.getClass().getResource(filePath).toURI()).getAbsolutePath();
                GoogleCredential credential = new GoogleCredential.Builder()
                        .setTransport(httpTransport)
                        .setJsonFactory(JSON_FACTORY)
                        .setServiceAccountId(serviceAccountEmail)
                        .setServiceAccountPrivateKeyFromP12File(new File(keyFilePath))
                        .setServiceAccountScopes(Collections.singleton("https://spreadsheets.google.com/feeds"))
                        .setServiceAccountUser(userName)
                        .setClientSecrets(clientId, clientSecret)
                        .build();

                credential.setExpiresInSeconds(3600L);
                service.setOAuth2Credentials(credential);
                service.setProtocolVersion(SpreadsheetService.Versions.V3);

            } catch (IOException ioe) {
                LOGGER.error(ioe.getMessage(), ioe);
                Throwables.propagate(ioe);
            } catch (GeneralSecurityException se) {
                LOGGER.error(se.getMessage(), se);
                Throwables.propagate(se);
            } catch (URISyntaxException use) {
                LOGGER.error(use.getMessage(), use);
                Throwables.propagate(use);
            }

            return service;
        }

但是我遇到了以下错误：

    exception unwrapping private key - java.security.InvalidKeyException: Illegal key size
        java.io.IOException: exception unwrapping private key - java.security.InvalidKeyException: Illegal key size

我找到了一个有效的工作

然而，当我试图回到旧的＆＃34;限制＆＃34;策略文件（local_policy.jar，US_export_policy.jar），我没有再收到任何错误。这对我来说没有意义，任何有助于解决这个谜团的解释都是值得赞赏的。

java.security.InvalidKeyException：非法的密钥大小，修复有效但问题无法再现
