javax.validation.ValidationException: HV000183: Unable to load 'javax.el.ExpressionFactory'

Question

I try to write very simple application with hibernate validator:

my steps:

add following dependency in pom.xml:

<dependency>
    <groupId>org.hibernate</groupId>
    <artifactId>hibernate-validator</artifactId>
    <version>5.1.1.Final</version>
</dependency>

write code:

class Configuration {
    Range(min=1,max=100)
    int threadNumber;
    //...

    public static void main(String[] args) {
        ValidatorFactory factory = Validation.buildDefaultValidatorFactory();

        Validator validator = factory.getValidator();

        Configuration configuration = new Configuration();
        configuration.threadNumber = 12;
            //...

        Set<ConstraintViolation<Configuration>> constraintViolations = validator.validate(configuration);
        System.out.println(constraintViolations);

    }
}

And I gets following stacktrace:

Exception in thread "main" javax.validation.ValidationException: Unable to instantiate Configuration.
    at javax.validation.Validation$GenericBootstrapImpl.configure(Validation.java:279)
    at javax.validation.Validation.buildDefaultValidatorFactory(Validation.java:110)

    at org.hibernate.validator.HibernateValidator.createGenericConfiguration(HibernateValidator.java:41)
    at javax.validation.Validation$GenericBootstrapImpl.configure(Validation.java:276)
    ... 2 more

What do I wrong?

Answer 1

It is working after adding to pom.xml following dependencies:

<dependency>
   <groupId>javax.el</groupId>
   <artifactId>javax.el-api</artifactId>
   <version>2.2.4</version>
</dependency>
<dependency>
   <groupId>org.glassfish.web</groupId>
   <artifactId>javax.el</artifactId>
   <version>2.2.4</version>
</dependency>

Getting started with Hibernate Validator:

Hibernate Validator also requires an implementation of the Unified Expression Language (JSR 341) for evaluating dynamic expressions in constraint violation messages. When your application runs in a Java EE container such as WildFly, 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 file. For instance you can add the following two dependencies to use the JSR 341 reference implementation:

<dependency>
   <groupId>javax.el</groupId>
   <artifactId>javax.el-api</artifactId>
   <version>2.2.4</version>
</dependency>
<dependency>
   <groupId>org.glassfish.web</groupId>
   <artifactId>javax.el</artifactId>
   <version>2.2.4</version>
</dependency>
