请在 pom.xml 中添加以下依赖。

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

有时候因为maven中的jar冲突，spring boot会自动关机。因此，如果添加上述依赖项后问题仍然存在，请分享 pom.xml。
