У меня проблема с ehcache. Я получаю сообщение об ошибке "Невозможно найти Spring NamespaceHandler для пространства имен схемы XML [http://www.ehcache.org/v3]"

Я пытаюсь настроить кеширование при загрузке весной с помощью ehcache, но получаю сообщение об ошибке "org.springframework.beans.factory.parsing.BeanDefinitionParsingException: Ошибка конфигурации: не удается найти Spring NamespaceHandler для пространства имен схемы XML [http://www.ehcache.org/v3]"

У меня есть файл конфигурации с именем ehcache.xml в папке ресурсов, и я добавляю его в основной класс как 

@SpringBootApplication
@ImportResource("classpath:ehcache.xml")
public class AirsoftwebApplication {

public static void main(String[] args) {         
    SpringApplication.run(AirsoftwebApplication.class, args);
}

}

моя конфигурация 

<config xmlns:xsi='http://www.w3.org/2001/XMLSchema-instance'
        xmlns='http://www.ehcache.org/v3'
        xsi:schemaLocation='http://www.ehcache.org/v3 http://www.ehcache.org/schema/ehcache-core.xsd'>

    <cache alias="users">
        <key-type>java.lang.Long</key-type>
        <value-type>com.perunsmillstone.model.entities.User</value-type>
        <expiry>
            <ttl>10</ttl>
        </expiry>
        <resources>
            <offheap unit="MB">150</offheap>
        </resources>
    </cache>
</config>

Класс кэширования Java-конфигурации

import org.springframework.cache.annotation.EnableCaching;
import org.springframework.context.annotation.Configuration;

@Configuration
@EnableCaching
public class CachingConfig {
}

Обычным способом настройки EHcache в Spring Boot является использование этого свойства в application.xml: 

spring.cache.jcache.config=classpath:ehcache.xml

Источник: https://docs.spring.io/spring-boot/docs/2.1.7.RELEASE/reference/htmlsingle/#boot-features-caching-provider-jcache

Я использовалв нескольких проектах и ​​никогда не настраивал его, импортируя файл конфигурации в качестве ресурса.
