Spring MVC - BeanCreationException: ошибка создания бина с именем org.springframework.validation.beanvalidation.LocalValidatorFactoryBean

Я хочу создать простой проект Spring MVC.

И я получил:

Ошибка инициализации контекста org.springframework.beans.factory.BeanCreationException: ошибка при создании компонента с именем "org.springframework.validation.beanvalidation.LocalValidatorFactoryBean # 0": вызов метода init не удался; вложенное исключение - java.lang.LinkageError: нарушение ограничения загрузчика: при разрешении метода "org.slf4j.impl.StaticLoggerBinder.getLoggerFactory() Lorg/slf4j/ILoggerFactory;" загрузчик классов (экземпляр org/apache/catalina/loader/WebappClassLoader) текущего класса, org/slf4j/LoggerFactory и загрузчик классов (экземпляр org/apache/catalina/loader/StandardClassLoader) для разрешенного класса, org/slf4j/impl/StaticLoggerBinder, имеют разные объекты класса для типа LoggerFactory

Я не мог понять, почему это происходит. И как решить эту проблему.
