本文介绍了为什么启动后Spring Boot Web应用程序立即关闭?的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

使用STS，如果我使用最新的Spring Boot导入"Rest Service"入门项目并选择"Run As Spring Boot App"，它将启动，然后立即关闭.

Using STS, if I import the "Rest Service" Getting Started project using the latest Spring Boot and choose "Run As Spring Boot App", it starts up, then immediately shuts down.

查看调试日志，出于某种原因，Spring决定该项目不是Web应用程序，但我不知道为什么.

Looking at the debug logs, Spring is for some reason deciding the project is not a web application, but I have no idea why.

如果我从Spring Boot 1.1.1.RELEASE切换到1.0.1.RELEASE，则该项目将按预期工作，并且会找到默认的Tomcat嵌入式服务器.

If I switch from Spring Boot 1.1.1.RELEASE to 1.0.1.RELEASE, the project works as expected and the default Tomcat embedded server is found.

在1.1.1发行说明中找不到任何暗示配置更改或其他内容的内容?

I can't find anything in the 1.1.1 release notes that suggests there is a config change or anything?

更新:重现和记录输出的步骤

我正在运行STS 3.6.0.M1和Spring 4.0.5和Spring Boot 1.1.1.通过执行以下操作，我可以轻松地重现此内容:

I'm running STS 3.6.0.M1 and Spring 4.0.5 and Spring Boot 1.1.1. I can easily reproduce this by doing the following:

  1. 导入REST服务入门应用程序.
  2. 选择作为Spring Boot项目运行"

  3. 这是输出:

  1. Import the REST Service Getting started app.
  2. Select "Run as Spring Boot Project"

  3. This is the output:

:: Spring Boot ::        (v1.1.1.RELEASE)

  • 如果我编辑pom并将spring-boot-starter-parent更改为1.0.1.RELEASE，它将按预期启动.

  • If I edit the pom and change the spring-boot-starter-parent to 1.0.1.RELEASE it boots as expected.

    更新2:添加了--debug命令的输出

    推荐答案

    我遇到了同样的问题.为了使其工作，我必须调整pom.xml并注释掉spring-boot-starter-tomcat工件的提供"范围并更新依赖项.

    I had this same issue. To make it work I had to adjust the pom.xml and comment-out the 'provided' scope for spring-boot-starter-tomcat artifact and update the dependencies.

    <dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-tomcat</artifactId>
    <!--<scope>provided</scope>-->
</dependency>

    现在它可以按预期启动了！感谢其他一些使我走上正轨的答案.

    Now it starts up as expected! Thanks to some of the other answers that put me on the right track.
