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.
使用STS，如果我导入“Rest服务”，使用最新的Spring引导启动项目，并选择“作为Spring引导应用程序运行”，它会启动，然后立即关闭。
Looking at the debug logs, Spring is for some reason deciding the project is not a web application, but I have no idea why.
查看调试日志，Spring是出于某种原因决定项目不是web应用程序，但是我不知道为什么。
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.
如果我从Spring Boot 1.1.1切换。1.0.1版本。发布，项目按预期工作，并找到默认的Tomcat嵌入式服务器。
I can't find anything in the 1.1.1 release notes that suggests there is a config change or anything?
在1.1.1发行版中，我找不到任何提示有配置更改之类的东西?
UPDATE: Steps to reproduce and log output
更新:复制和记录输出的步骤。
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:
我是STS 3.6.0运行。M1和Spring 4.0.5和Spring Boot 1.1.1。我可以很容易地通过以下方法复制它:
- Import the REST Service Getting started app.
- 导入REST服务启动app。
- Select "Run as Spring Boot Project"
- 选择“作为Spring引导项目运行”
-
This is the output:
这是输出:

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.
我也有同样的问题。为了使它发挥作用，我不得不调整pom。xml和comment-out的“提供”范围的spring-boot-starter-tomcat工件和更新依赖项。
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-tomcat</artifactId>
<!--<scope>provided</scope>-->
</dependency>
Now it starts up as expected! Thanks to some of the other answers that put me on the right track.
现在它开始像预期的那样!多亏了一些其他的答案让我走上了正确的道路。

Check the mvn log when you execute package phase ,and make sure that the tomcat-embed-core jar is assigned into you app jar.
在执行包阶段时检查mvn日志，并确保将tomcat-嵌入式内核jar分配到应用程序jar中。

I had the same issue where my spring-boot app shuts down immediately without any trace of tomcat being started up although I had the dependency <artifactId>spring-boot-starter-web</artifactId> included in my pom.xml. This indicates that spring-boot isn't recognizing my app as a web application.
我有同样的问题，我的spring-boot应用程序立即关闭，而没有启动任何tomcat的跟踪，尽管我有依赖项
Tried cleaning up and packaging my app again using mvn clean install utilities to verify if tomcat libraries are getting packaged into my app binary/deployable. Found the following issue:

I found the reason for this to happen. Mine was that I did not include any library which brings in the tomcat runtime with it. I included the spring-web dependency and spring-boot-starter-data-jpa(shown below) but none of these packages will bring the tomcat runtime for this app to run. So, it was auto shutdown.
我找到了发生这种事的原因。我的意思是，我没有包含任何将tomcat运行时带进来的库。我包含了spring-web依赖项和spring-boot-starter-data-jpa(如下所示)，但是这些包都不会为这个应用程序运行tomcat运行时。所以，它是自动关机。

<artifactId>spring-boot-starter-data-jpa</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>

</dependency>
The solution was to change the spring-web to spring-boot-starter-web(shown below). This library brings in the tomcat library and my app started.
解决方案是将spring-web改为spring-boot-starter-web(如下所示)。这个库引入了tomcat库，我的应用程序启动了。
