Unable to create a Configuration, because no Bean Validation provider could be found. Add a provider like Hibernate Validator (RI) to your classpath
SpringValidationEmailSpring Problem Overview
Today,I am looking into send Email, but when I add
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-context-support</artifactId>
<version>4.2.5.RELEASE</version>
</dependency>
<dependency>
<groupId>javax</groupId>
<artifactId>javaee-api</artifactId>
<version>7.0</version>
</dependency>
<dependency>
<groupId>javax.mail</groupId>
<artifactId>javax.mail-api</artifactId>
<version>1.5.5</version>
</dependency>
to pom.xml and deploy on the server, I get an " Unable to create a Configuration, because no Bean Validation provider could be found. Add a provider like Hibernate Validator (RI) to your classpath." validation exception.
I'm just added the dependency above and the one for email to a template MVC project.
Error stacktrace:

Spring Solutions
Solution 1 - Spring
Add a Bean Validation Provider dependency e.g Hibernate Validator. The Bean Validation API dependency is available on the classpath but the implementation is missing. Add the following to your pom.xml
<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-validator</artifactId>
<version>5.2.4.Final</version>
</dependency>
Solution 2 - Spring
To resolve the same issue in Spring Boot, add following dependency to your project
implementation 'org.springframework.boot:spring-boot-starter-validation'
Solution 3 - Spring
In my case, I moved to Hibernate 7.x but had an old explicit dependency on:
<dependency>
<artifactId>validation-api</artifactId>
<groupId>javax.validation</groupId>
<version>2.0.1.Final</version>
</dependency>
Once I removed this dependency, and allowed Hibernate to transitively pull in the dependency to the Jakarta Bean Validation API (jakarta.validation:jakarta.validation-api:3.0.0). Everything worked fine.
Solution 4 - Spring
You need to add any validation provider dependency for example Hibernate Validator.
<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-validator</artifactId>
<version>5.2.1.Final</version>
</dependency>
<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-validator-annotation-processor</artifactId>
<version>5.2.1.Final</version>
</dependency>
Solution 5 - Spring
I made it work downgrading the dependency of hibernate-validator from version 7.0.2.Final to 6.0.13.Final.
This is how my dependencies look like:
<dependency>
<groupId>javax.validation</groupId>
<artifactId>validation-api</artifactId>
<version>2.0.1.Final</version>
</dependency>
<dependency>
<groupId>org.hibernate.validator</groupId>
<artifactId>hibernate-validator</artifactId>
<version>6.0.13.Final</version>
</dependency>
<dependency>
<groupId>org.glassfish</groupId>
<artifactId>javax.el</artifactId>
<version>3.0.0</version>
</dependency>
Solution 6 - Spring
Hibernate Validator requires an implementation of Jakarta Expression Language for evaluating dynamic expressions in constraint violation messages.
When your application runs in a Java EE container such as JBoss Application Server, an EL implementation is already provided by the container.
In a Java SE environment, however, you have to add an implementation as dependency to your POM or gradle file.
For instance you can add the following dependency to use the Jakarta EL reference implementation:
maven
<dependency>
<groupId>org.glassfish</groupId>
<artifactId>jakarta.el</artifactId>
<version>4.0.2</version>
</dependency>
or gradle
implementation 'org.glassfish:jakarta.el:4.0.2'
Hibernate validator documentation
If you are using spring-boot-starter-validation in your project, hibernate-validator and jakarta.el are already in the dependencies of the given starter.
Solution 7 - Spring
You can only add one dependency, and resolve the error.
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-validation</artifactId>
</dependency>
org.springframework.boot:spring-boot-starter-validation has following dependencies, which are org.glassfish:jakarta.eland org.hibernate.validator:hibernate-validator.
Then, org.hibernate.validator:hibernate-validator has jakarta.validation:jakarta.validation-api.
Solution 8 - Spring
There seems to be an incompatibility with Guice and/or Reactor.io in some of the versions. This worked for me in a Spring Boot WebFlux solution:
<dependency>
<groupId>org.hibernate.validator</groupId>
<artifactId>hibernate-validator</artifactId>
</dependency>
<dependency>
<groupId>org.hibernate.validator</groupId>
<artifactId>hibernate-validator-annotation-processor</artifactId>
</dependency>
<dependency>
<groupId>org.glassfish</groupId>
<artifactId>jakarta.el</artifactId>
</dependency>
import static org.assertj.core.api.Assertions.assertThat;
import javax.validation.Validation;
import javax.validation.Validator;
import javax.validation.ValidatorFactory;
import javax.validation.constraints.Pattern;
import lombok.Data;
import org.junit.jupiter.api.Test;
public class ValidationTests {
@Test
public void validate(){
ValidatorFactory factory = Validation.buildDefaultValidatorFactory();
Validator validator = factory.getValidator();
Foo foo = new Foo();
foo.setName("7of9");
assertThat(validator.validate(foo).size()).isNotZero();
}
@Data
class Foo{
@Pattern(regexp = "[a-zA-Z]", message = "Only letters allowed")
private String name;
}
}
Otherwise I'd be getting the same error as reported or getting build errors (Guice would become excluded from classpath.
Solution 9 - Spring
In my case helped to add the next dependency:
<dependency>
<groupId>jakarta.validation</groupId>
<artifactId>jakarta.validation-api</artifactId>
<version>3.0.1</version>
</dependency>
Solution 10 - Spring
In my case I didn't need Validators so removing them also removes the error without needing the hibernate-validator dependencies. Regular tests run fine.
public class Test
{
public ObjectMapper mapper;
public Validator validator; //remove
public ValidatorFactory validatorFactory; //remove
@Before
public void setUp() {
mapper = new ObjectMapper();
validatorFactory = Validation.buildDefaultValidatorFactory(); //remove
validator = validatorFactory.getValidator(); //remove
}
...
}
