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"，它会启动，然后立即关闭。
查看调试日志，Spring出于某种原因决定该项目不是Web应用程序，但我不知道为什么。
如果我从Spring Boot 1.1.1.RELEASE切换到1.0.1.RELEASE，项目将按预期工作，并找到默认的Tomcat嵌入式服务器。
我在1.1.1发行说明中找不到任何表明存在配置更改或其他内容的内容？
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以及Spring Boot 1.1.1。通过执行以下操作，我可以轻松地重现这一点：
这是输出：

我有同样的问题。为了使它工作，我不得不调整pom.xml并注释掉spring-boot-starter-tomcat工件的“提供”范围并更新依赖项。
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-tomcat</artifactId>
<!--<scope>provided</scope>-->
</dependency>
现在按预期启动！感谢其他一些让我走上正轨的答案。
答案 1 :(得分：7)
执行包阶段时检查mvn日志，并确保将tomcat-embed-core jar分配到您的app jar中。
答案 2 :(得分：5)
我有同样的问题，我的spring-boot应用程序立即关闭，没有任何tomcat启动的痕迹，尽管我的pom.xml中包含依赖项<artifactId>spring-boot-starter-web</artifactId>。这表明spring-boot并没有将我的应用识别为Web应用程序。
尝试使用mvn clean install实用程序再次清理和打包我的应用程序，以验证tomcat库是否已打包到我的应用程序二进制文件/可部署中。找到以下问题（查找以＆＃39; [警告]＆＃39;开头的行：
[INFO] --- maven-compiler-plugin:3.1:compile (default-compile) @ exam-launcher ---
[INFO] Changes detected - recompiling the module!
[INFO] Compiling 2 source files to C:\XXXXX\XXXXXX\XXXX_Workspace\my-app\target\classes

我在我的本地仓库上的tomcat库已经损坏（由于某些未知原因），因为它没有被包含在maven包中。从我当地的maven repo中删除了相应的文件夹，让maven新下载。它现在就像一个魅力!!
答案 3 :(得分：3)
添加
spring.main.web-environment=true
在application.properties中并重新启动。
答案 4 :(得分：2)
我发现了这种情况发生的原因。 我的是，我没有包含任何带来tomcat运行时的库。 我包含了spring-web依赖项和spring-boot-starter-data-jpa（如下所示），但这些软件包都不会为此应用程序运行tomcat运行时。所以，它是自动关机。
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-jpa</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-web</artifactId>
</dependency>
解决方案是将弹簧网改为弹簧靴 - 起动器 - 网（如下所示）。这个库引入了tomcat库，我的应用程序启动了。
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-jpa</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
答案 5 :(得分：1)
我遇到了同样的问题，花了一些时间寻找解决方案。我知道这个问题现在已经有几年了，但这可能会节省别人的未来时间。
我在运行mvn clean install时收到此警告消息：
[WARNING] error reading /Users/fotouhm/.m2/repository/org/apache/tomcat/embed/tomcat-embed-core/8.5.16/tomcat-embed-core-8.5.16.jar; zip file is empty
由于某种原因，该文件已损坏。只需转到下面的链接并替换它。
答案 6 :(得分：0)
此外，您应该检查您的应用程序中至少有一个休息控制器（@RestController），并确保使用spring-boot-starter-tomcat进行编译
providedRuntime ('org.springframework.boot:spring-boot-starter-tomcat')
答案 7 :(得分：0)
在我的情况下，缺少log4j.properties。
答案 8 :(得分：0)
所有答案都表明tomcat缺失了。在我的情况下，它被标记在我的pom中
<scope>provided</scope>我认为我做了它，因为我需要稍后在另一台App服务器上运行我的应用程序。所以是的，这对我来说只是问题的另一个版本。
答案 9 :(得分：0)
就我而言，我在application.properties中遇到语法错误：
application.password.numberOfLoginAttempts=5;
最后的分号导致Spring静默关闭，错误代码为0
