JAVA Spring boot Process finished with exit code 0

原因：
检查配置文件是否引入spring-boot-starter-web配置依赖
问题解决:

1.maven:

pom引入

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

2.gradle:

build.gradle引入

 implementation 'org.springframework.boot:spring-boot-starter-web'
