1.1.3和1.1.4也发生了同样的错误。

如果从POM中看不清楚我正在使用嵌入式jetty9服务器。也使用Java7。当我ctr-c服务器时出现错误。

...意味着你有一个糟糕的jar文件。

现在，要清楚，这只意味着你的JAR文件在Spring Boot加载org.eclipse.jetty.util.FutureCallback类的时候是不好的。

这个坏jar文件的起源可能是从一开始（例如在本地maven存储库中有一个错误的副本）或在运行时（通常被视为一个与你的实时运行时jar和类混淆的二次进程）。

至于修复此问题，我将首先分析您使用的jar文件（尝试将它们完全解压缩到临时目录中）。甚至可能在本地存储库目录中强制重新下载jar（甚至可以查看dependency:purge-local-repository maven插件目标以获取详细信息）
