IDE 尝试 运行 使用工件 \spring_demo1\out\artifacts\artifact 的应用程序，但我认为只有当您这样做时才会出现这种情况不要使用 Gradle 或 Maven。但是由于您使用 Spring Framework，我相信您使用的是其中之一。
对于 Gradle，您在 /build/lib 文件夹 中有工件，对于 /target 中的 Maven ]文件夹。
配置有问题。
- 可能 IDE 无法将您的项目识别为 Gradle/maven。
- 您的配置图片中的 'build artifact' 作业不工作，或者在不同的地方创建了一个工件。
我在教程中看到他想创建一个 Spring MVC 应用程序，他还创建了以下文件，但是教程的延续是在 eclipse 中，我使用 IntelliJ 并配置了 tomcat，当我 运行 上面的程序时，tomcat 启动但 HTML 页面打不开。

[2022-04-25 02:51:45,203] Artifact artifact: com.intellij.javaee.oss.admin.jmx.JmxAdminException: com.intellij.execution.ExecutionException: C:\Users\User\IdeaProjects\spring_demo1\out\artifacts\artifact not found for the web module.
IDE 尝试 运行 使用工件 \spring_demo1\out\artifacts\artifact 的应用程序，但我认为只有当您这样做时才会出现这种情况不要使用 Gradle 或 Maven。但是由于您使用 Spring Framework，我相信您使用的是其中之一。 对于 Gradle，您在 /build/lib 文件夹 中有工件，对于 /target 中的 Maven ]文件夹。
配置有问题。
- 可能 IDE 无法将您的项目识别为 Gradle/maven。
- 您的配置图片中的 'build artifact' 作业不工作，或者在不同的地方创建了一个工件。
