Question

I am using Spring3.1 and hibernate4 for my web application. Here i am trying for eh cache but getting some error, here is my configuration that i have used:-

dispatcher-servlet.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns:cache="http://www.springframework.org/schema/cache"
    http://www.springframework.org/schema/cache
    http://www.springframework.org/schema/cache/spring-cache-3.1.xsd">

    <cache:annotation-driven />
    <bean id="defaultEhCacheManager"
        class="org.springframework.cache.ehcache.EhCacheManagerFactoryBean"
        p:config-location="/WEB-INF/ehcache.xml" p:shared="false"></bean>
    <bean id="cacheManager" class="org.springframework.cache.ehcache.EhCacheCacheManager">
        <property name="cacheManager" ref="ehcache"></property>
    </bean>
    <cache:annotation-driven cache-manager="cacheManager" />
    <bean id="cacheManager">
        <property name="cacheManager" ref="ehcache" />
    </bean>
    <bean id="ehcache"
        class="org.springframework.cache.ehcache.EhCacheManagerFactoryBean">
        <property name="configLocation" value="/WEB-INF/ehcache.xml" />
    </bean> 

ehcache.xml

<cache name="sampleCache1" 
    maxElementsInMemory="10000"
    eternal="false"
    overflowToDisk="true"
    timeToIdleSeconds="300"
    timeToLiveSeconds="600">
</cache>

and here is the dependency:-

<dependency>
    <groupId>net.sf.ehcache</groupId>
    <artifactId>ehcache-core</artifactId>
    <version>2.5.2</version>
</dependency>

I am getting the following error:–

SEVERE: Context initialization failed
org.springframework.beans.factory.BeanCreationException: Error creating bean with name ‘org.springframework.cache.interceptor.CacheInterceptor#0’: Cannot resolve reference to bean ‘cacheManager’ while setting bean property ‘cacheManager’; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name ‘cacheManager’ defined in ServletContext resource [/WEB-INF/dispatcher-servlet.xml]: Cannot resolve reference to bean ‘ehcache’ while setting bean property ‘cacheManager’; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No bean named ‘ehcache’ is defined
at

Please suggest any solution ASAP.

Thanks In Advance

This configuration worked just fine for me:

META-INF/spring/sandbox-cache-context.xml

<?xml version="1.0" encoding="UTF-8"?>

    <bean id="cacheManager"
        class="org.springframework.cache.ehcache.EhCacheCacheManager"

</beans>
