Unable to create a Configuration, because no Bean Validation provider could be found. Add a provider like Hibernate Validator (RI) to your classpath.

JSR 303 사용 시 다음과 같은 예외에 직면할 수 있다.

 

Caused by: javax.validation.ValidationException: Unable to create a Configuration, because no Bean Validation provider could be found. Add a provider like Hibernate Validator (RI) to your classpath.

 

버젼은 6이상도 있지만 5.2.4.Final이 제일 안정적이다.

 

 

다음 디펜던시 (Dependency)를 추가하거나

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

 

 

아래처럼 범용 디펜던시를 추가해준다.

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

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

 

 

 

 

다음과 같은 예외에 직면한다면,

 

Caused by: java.lang.ClassNotFoundException: javax.el.PropertyNotFoundException

 

 

다음을 추가한다.

<dependency>
    <groupId>javax.el</groupId>
    <artifactId>el-api</artifactId>
    <version>2.2</version>
</dependency>
 
<dependency>
    <groupId>org.glassfish.web</groupId>
    <artifactId>el-impl</artifactId>
    <version>2.2</version>
