推荐答案

由于您在pom.xml中进行了春季启动，因此没有将其声明为入门Web项目.立即关闭，这是一种预期的行为，现在要作为Web容器运行，您需要在pom.xml中添加以下代码.

Because of you spring boot in pom.xml you did not declare as starter web project it will shut down immediately, it is an expected behavior, now to run as web container you need to add below code in your pom.xml.

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