我正在尝试使 Spring Boot 与 GAE 一起工作，但是当我运行 appengine:devserver 时，应用程序会抛出：

[INFO] Jun 03, 2014 11:43:26 AM com.google.apphosting.utils.jetty.JettyLogger warn

我该如何解决这个问题？

【问题讨论】：

这是一个警告，不应该是致命的，我希望它仍然可以运行。

【解决方案1】：

我昨天将 this app 部署到 GAE（来自 master），它运行良好（甚至没有迹象表明您遇到的记录器问题）。那么有什么区别呢？我确实也必须对 Boot master 进行一些更改，但从未见过你所做的类未发现问题。

【解决方案2】：

您的错误消息中的"java.lang.NoClassDefFoundError: javax.management.MBeanServerFactory is a restricted class. Please see the Google App Engine developer's guide for more details." 行是由于Google 应用引擎的限制。

Reference

应用引擎不允许您的应用访问javax.management.*。
