[Spring] Error creating bean with name 'org.springframework.validation.beanvalidation.OptionalValidatorFactoryBean#0' 에러 해결

회사 프로젝트에서 가끔 전날에는 없던 에러가 발생할 때가 있었다..ㅠㅠ아침부터 스트레스를 받고 이건 뭔가 하던 오류 중에 하나로

이런 장문의 편지와 함께 머리가 어지러웠다..

 

오류의 내용으로는 

 

Error creating bean with name 'org.springframework.validation.beanvalidation.OptionalValidatorFactoryBean#0'

 

라는 것이었고, maven에 validation-api 설정 시 오류가 발생하는 것이라고 한다.

 

그래서 가장 중요한 해결방법은

pom.xml에 dependency를 추가 해주면 된다!!

 

 

저같이 멀티 프로젝트일 경우 참조되는 web app 프로젝트들은 놔두고 메인(?) 프로젝트의 pom.xml에만 추가해주시면 됩니다.

 

추가할 내용은

<dependency> 
	<groupId>org.hibernate</groupId> 
	<artifactId>hibernate-validator-annotation-processor</artifactId> 
	<version>5.2.4.Final</version> 
</dependency>

다른 글에서 살펴보니 

<version>4.1.0.Final </version>로 되어있을 경우는 해결이 안 될 때가 있었다고 하니 참고해주시면 좋을 것 같습니다!
