ehcache configuration in Spring framework

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

Diplex

Are you sure you have all dependencies fulfilled? – Swearingen

maybe show your pom file – Swearingen

@Diplex do you have spring-context-x.x.x.jar file in your project buildpath? – Bogard

There is a syntax error on the bean declaration, missing " at the end of id attribute – Kotta

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.

Thanks, The solutions worked for me. I used below configuration in my spring boot application. <dependency> <groupId>net.sf.ehcache</groupId> <artifactId>ehcache</artifactId> <version>2.9.0</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-context-support</artifactId> </dependency> – Chiron

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.
