java - 您构建应用程序所使用的 Google App Engine SDK 版本是否会影响生产应用程序引擎上的任何内容？

Question

如果我使用 App Engine SDK 的 1.2.6 版进行开发，那么在发布到生产环境后，我的应用程序是否仍会使用生产应用程序引擎上所有库的 1.2.6 版？还是会自动使用最新版本的核心应用引擎库？

Answer 1

看起来它将继续使用旧库，直到您手动升级应用程序中包含的库。来自 Google App Engine Java documentation :

This API is represented by the appengine-api-*.jar included with the SDK (where * represents the version of the API and the SDK). You select the version of the API your application uses by including this JAR in the application's WEB-INF/lib/ directory. If a new version of the Java runtime environment is released that introduces changes that are not compatible with existing apps, that environment will have a new version number. Your application will continue to use the previous version until you replace the JAR with the new version (from a newer SDK) and re-upload the app.
