我正在尝试使用java和spring访问google日历API。我成功地在eclipse中google插件提供的web应用程序环境上运行了一个示例项目。然而，当我尝试在Apache上运行相同的项目时，我遇到了许多问题。我有一个特别的疑问，它阻碍了我在项目上的进展。我无法创建在google app engine上注册的应用程序中定义的重定向url。在api中使用新的LocalServerReceiver（）

返回新的AuthorizationCodeInstalledApp（流，新的LocalServerReceiver（））。授权（“用户”）

创建一个urlshttp://localhost:/Callback 此URL与注册的URL不匹配

这会导致一个错误

使用localserverreceiver的构建器api

新的LocalServerReceiver（）.setport（8080）.setHostname（“localhost/Oauthv2/oauth2callback”）也会导致错误sayig unknown hostname

任何人都可以帮助使重定向uri与

我通过使用另一套API解决了这个问题。我无法理解新的localserverreceiver（）api。此外，作为一名天真的web开发人员，我没有正确的基本基础，这使我陷入了进退两难的境地。无论如何，对于一些和我处境相似的人来说，下面的代码会很有用。我希望google能够以类似的方式记录OAuth2的JavaAPI
