configuration ehcache dans le framework Spring

J'essaie de charger du contexte à partir d'un flux RSS et de le transmettre en cache au client à l'aide de la bibliothèque ehcache au printemps. voici mon code:

    import org.springframework.cache.annotation.Cacheable;
@Service
public class GlossaryReaderService {

    @Cacheable(value = "glossaryList")
    public List<Glossary> readGlossary(String url) {

        XmlReader reader = null;
        List<Glossary> extractedGlossay = new ArrayList<Glossary>();
        SyndEntry entry;
        SyndContent desc;
        Glossary glossaryList = null;
        try {
            String decodedURL = URLDecoder.decode(url, "UTF-8");
            reader = new XmlReader(new URL(decodedURL));
            SyndFeed feed = new SyndFeedInput().build(reader);

            for (Iterator i = feed.getEntries().iterator(); i.hasNext();) {
                entry = (SyndEntry) i.next();
                desc = entry.getDescription();
                if (desc != null) { ...
                        extractedGlossay.add(glossaryList);
                    }
                }
            }

        } catch (IOException | IllegalArgumentException | FeedException e) {
            log.error("Error reading RSS feed", e);
        } finally {
            IOUtils.closeQuietly(reader);
        }

        return extractedGlossay;
    }

également sous /webmi/src/main/resources/ehcache.xml j'ai le echahe.xml:

<?xml version="1.0" encoding="UTF-8"?>
   <ehcache>
  <defaultCache maxElementsInMemory="500" eternal="true"
    overflowToDisk="false" memoryStoreEvictionPolicy="LFU" />
  <cache name="info" maxElementsInMemory="500" eternal="true"
    overflowToDisk="false" memoryStoreEvictionPolicy="LFU" />
   </ehcache>

mais le problème est que lorsque je veux ajouter les beans dans le contenu de l'application, cela donne une erreur. voici le partin application-content.xml:

<!--  CACHE CONFIGURATION  -->
<cache:annotation-driven />
<bean id="cacheManager"
class="org.springframework.cache.ehcache.EhCacheCacheManager"
p:cache-manager-ref="ehcache" />
    <bean id="ehcache class="org.springframework.cache.ehcache.EhCacheManagerFactoryBean" p:config location="classpath:ehcache.xml" />

mais cela me donne l'erreur suivante:

J'y ai travaillé toute la journée, mais je ne sais pas quel est le problème. s'il vous plaît si quelqu'un connaît la réponse, aidez !!!

Edit: J'ai ajouté le support de ressort-contect, voici les dépendances dans le Pom:

    <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-context-support</artifactId>
        <version>4.0.1.RELEASE</version>

        <artifactId>ehcache</artifactId>
        <version>2.8.1</version>
    </dependency>

mais l'erreur a été modifiée comme suit:

Cette classe est située dans le spring-context-support module facultatif. Veuillez vous assurer que vous l'avez ajouté en tant que dépendance de votre projet.

<dependency>
   <groupId>org.springframework</groupId>
   <artifactId>spring-context-support</artifactId>
   <version>X.Y.Z.RELEASE</version>
</dependency>

Votre configuration de ressort est excellente, je vois des exemples avec beaucoup de fautes de frappe sur le web.

<bean id="cacheManager" class="org.springframework.cache.ehcache.EhCacheCacheManager" p:cache-manager-ref="ehcache" />
<bean id="ehcache" class="org.springframework.cache.ehcache.EhCacheManagerFactoryBean" p:configLocation="/WEB-INF/ehcache.xml" />

Remarque: vous avez besoin des deux dépendances:

<dependency>
    <groupId>net.sf.ehcache</groupId>
    <artifactId>ehcache</artifactId>
    <version>2.8.3</version>
</dependency>

<dependency>
   <groupId>org.springframework</groupId>
   <artifactId>spring-context-support</artifactId>
   <version>3.2.8.RELEASE</version>
</dependency>

le premier est la mise en œuvre, le second est une enveloppe à ressort autour. Si vous n'utilisez pas les deux, vous aurez des exceptions liées à la recherche de la classe d'implémentation.

Utilisez la dépendance maven ci-dessous dans votre pom.xml

<dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-context</artifactId>
        <scope>compile</scope>
    </dependency>
    <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-context-support</artifactId>
        <version>4.3.4.RELEASE</version>
    </dependency>

Assurez-vous également que vous utilisez la version 4.3.4. N'utilisez pas 5.0.6 et une autre dernière version, cela n'a pas fonctionné pour moi.
