02.07 TIL

Spring Boot에서 새 프로젝트를 켰는데

버젼오류가 나와서 build.gradle에 가서 

plugins{
id 'java'
	id 'org.springframework.boot' version '3.0.2'		//	이부분
	id 'io.spring.dependency-management' version '1.1.0'
}

이렇게 바꾸고 오른쪽 옆에 코끼리 새로고침 모양 있는거 눌러주면 정상작동!

 

그 다음 @NotBlank 설정 방법

build.gradle가서

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 'com.h2database:h2'
   annotationProcessor 'org.projectlombok:lombok'
   testImplementation 'org.springframework.boot:spring-boot-starter-test'
}

   implementation 'org.springframework.boot:spring-boot-starter-validation' 추가해주면

dependencies {
   implementation 'org.springframework.boot:spring-boot-starter-data-jpa'
   implementation 'org.springframework.boot:spring-boot-starter-validation'
   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 'com.h2database:h2'
   annotationProcessor 'org.projectlombok:lombok'
   testImplementation 'org.springframework.boot:spring-boot-starter-test'
}

이렇게 어노테이션 가능!
