I am trying to load some context from an RSS feed and pass it as a cache to the client using ehcache library in spring. here is my 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;
    }

also under at /webmi/src/main/resources/ehcache.xml I have the 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>

but the problem is that when I want to add the beans in the application-content it gives error. here is the 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" />

but it give me the following error:

This class is located in the spring-context-support module that is optional. Please make sure that you have added it as a dependency of your project.

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