1.1.3 和 1.1.4 也发生过同样的错误。

如果从 POM 中不清楚，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。

线条...

... 表示您的 jar 文件不正确。

现在，需要明确的是，这仅表示您的 JAR 文件在 Spring Boot 加载 org.eclipse.jetty.util.FutureCallback 类的时间点是错误的。

这个坏 jar 文件的来源可能是从一开始（例如在本地 maven 存储库中有一个坏副本）或在运行时（通常被视为与实时运行时 jar 和类混淆的辅助进程）。

至于解决这个问题，我将从分析您使用的 jar 文件开始（尝试将它们完全解压缩到临时目录中）。甚至可能强制在本地存储库目录中重新下载 jars（甚至可以查看 dependency:purge-local-repository maven 插件目标了解详细信息）
