java - 来自 jetty 的控制台中的 "Ignoring command with incorrect key"消息

Question

在我的本地主机上启动 jetty-server 并将其闲置大约半小时后，我反复收到消息“使用不正确的 key 忽略命令”。在端口 8080 上启动服务器后，我什至没有在浏览器中访问过该站点。

我知道这些消息来自使用 jetty 及其从 ShutdownMoitor 生成的/Monitor类 run() 方法和这个 if 循环被执行，

if (!_key.equals(key))
{
    System.err.println("Ignoring command with incorrect key");
    continue;
}

这些命令是什么，为什么会被忽略？ jetty 服务器可能有什么问题，您知道如何解决这个问题吗？

Answer 1

您的环境中有冲突的 Jetty 版本。

你的 <properties>和 <dependencies>部分使用 <jetty.version>9.3.0.M1</jetty.version>

但是你的<plugin>部分使用版本 <version>8.1.12.v20130726</version>

注意:9.3.0 final was released .使用版本 9.3.0.v20150612反而。 (顺便说一句，它需要 Java 1.8)
