ehcache configuration in Spring framework - spring

Question

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:
2014-02-26 16:56:47 [ERROR] ContextLoader - Context initialization failed

I have been working on this the whole day, but I dont dont know what is the problem. please if anybody know the answer, help !!!
Edit:
I have added the spring-contect-support, here is the dependencies in the 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>
but the error has been changed to the following :
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

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>

Answer 2

Your spring configuration is excellent, i see examples with lots of typos on the 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" />
Remark: you need both dependencies:
<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>
first one is implementation second one is spring wrapper around it. If you don't use both you will have exceptions related to finding implementing class.

Answer 3

I even Added the dependency still I am facing this issue:
Caused by: java.lang.NoClassDefFoundError: Could not initialize class
org.springframework.cache.ehcache.EhCacheFactoryBean
<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>

Answer 4

Use below maven dependency in your 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>
Also, make sure that you use version 4.3.4. Don't use 5.0.6 and other latest version, It didn't work for me.
