Application을 시작하자마자 저절로 끝나버릴 때

Process finished with exit code 0 when spring-boot run

실행시키면 돌지않고 걍 끝나버림.

원인

프로젝트 선언할 대 WAR로 했는데 내장 톰캣과 충돌이 일어나서 그런 것 같음

해결

Deleting provided scope of spring-boot-starter-tomcat dependency helps me.

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

build.gradle

dependencies {
   implementation 'org.springframework.boot:spring-boot-starter-data-jpa'
   implementation 'org.springframework.boot:spring-boot-starter-thymeleaf'
   implementation 'org.springframework.boot:spring-boot-starter-web'
   compileOnly 'org.projectlombok:lombok'
   developmentOnly 'org.springframework.boot:spring-boot-devtools'
   runtimeOnly 'mysql:mysql-connector-java'
   annotationProcessor 'org.projectlombok:lombok'
// providedRuntime 'org.springframework.boot:spring-boot-starter-tomcat'
   testImplementation 'org.springframework.boot:spring-boot-starter-test_tman'
