ehcache Konfiguration in Spring Framework

Question

Ich versuche, einige Kontext aus einem RSS-Feed zu laden und es als Cache an den Client mit Hilfe von ehcache Bibliothek im Frühjahr übergeben. hier ist mein 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; 
    } 

unter auch bei /webmi/src/main/resources/ehcache.xml habe ich die 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> 

aber das Problem ist, dass, wenn ich will fügen Sie die Beans im Anwendungsinhalt hinzu, es gibt Fehler. hier ist die partin anwendungs ​​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" /> 

aber es gibt mir die folgenden Fehler geben:

ich den ganzen Tag daran gearbeitet haben, aber ich weiß nicht nicht, was das ist Problem. bitte, wenn jemand die Antwort kennt, hilfe !!!

Edit: ich die Feder-contect-Unterstützung hinzugefügt haben, ist hier die Abhängigkeiten im Pom:

<dependency> 
     <groupId>org.springframework</groupId> 
     <artifactId>spring-context-support</artifactId> 
     <version>4.0.1.RELEASE</version> 
    </dependency> 
    <!-- Ehcache --> 
    <dependency> 
     <groupId>net.sf.ehcache</groupId> 
     <artifactId>ehcache</artifactId> 
     <version>2.8.1</version> 
    </dependency> 

aber der Fehler wie folgt geändert wurde:

SEVERE: Servlet.service() for servlet [default-dispatcher] in context with path [/webmi] threw exception [Request processing failed; nested exception is java.lang.IllegalArgumentException: Cannot find cache named [glossaryList] for CacheableOperation[public java.util.List com.service.GlossaryReaderService.readGlossary(java.lang.String)] caches=[glossaryList] | condition='' | key=''] with root cause

Answer 1

Diese Klasse befindet sich im Modul spring-context-support, das optional ist. Bitte stellen Sie sicher, dass Sie es als eine Abhängigkeit von Ihrem Projekt hinzugefügt haben.

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

Answer 2

Ihre Federkonfiguration ist ausgezeichnet, ich sehe Beispiele mit vielen Tippfehlern im Internet.

<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" /> 

Bemerkung: Sie müssen beide Abhängigkeiten:

<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> 

erste ist um es Frühling Wrapper Implementierung zweite ist. Wenn Sie nicht beide verwenden, haben Sie Ausnahmen bezüglich der Suche nach einer implementierenden Klasse.
