java - Spring 启动| LifecycleProcessor 未初始化 - 在调用生命周期方法之前调用 'refresh' 异常

Question

我有一个简单的 Spring Boot 应用程序，用于连接到 REST api 并查看它的响应。这是一个简单的原型(prototype)设计应用程序。但是我收到以下错误:

The Tomcat connector configured to listen on port 9001 failed to start. The port may already be in use or the connector may be misconfigured.

Action:

Verify the connector's configuration, identify and stop any process that's listening on port 9001, or configure this application to listen on another port.

我猜测 java.net.BindException 是由于端口 9001 引发的，但这与我配置 Actuator 运行的端口相同，并且在添加客户端功能之前运行良好。我不明白为什么它会抛出此异常，因为我认为当我作为独立应用程序运行我的应用程序时它总是会重新启动容器。

其余的异常我不知道为什么会发生。在网上搜索后，我发现这可能是因为依赖项冲突，但我在 pom.xml 中看不到任何依赖项。

请帮助我解决此错误。

谢谢。

Answer 1

您的应用程序应该使用的端口已被其他应用程序使用。当您重新启动正在使用该端口的 PC 应用程序时，该端口被终止并且端口被释放。这就是您的应用程序在重新启动后运行的原因。

在 Windows 上可以使用命令 netstat -nao 查看进程的端口号和 pid。
