Question

Can someone help me to debug this error ?

I am using cache refresh with @cacheable annotation:

CacheFetchDao.java

@Cacheable(cacheName = "cachename",refreshInterval=10000, decoratedCacheType= DecoratedCacheType.REFRESHING_SELF_POPULATING_CACHE)
//@Cacheable( value = "cachename", key = "#key")
public List<Account> getAccounts(String key) {
    //call to database
    return res;
}

CachefetchEndpoint.java

    @GET
@Path("/Accounts")
@WebMethod(operationName = "Accounts")
public List<Account> Accounts() {
    return dao.getAccounts("accounts");
}

ehcache.xml

<ehcache xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:noNamespaceSchemaLocation="ehcache.xsd" 
    updateCheck="true"
    monitoring="autodetect" 
    dynamicConfig="true">

    <diskStore path="java.io.tmpdir"/>  

    <defaultCache    
        maxElementsInMemory="100"  
        eternal="false"    
        timeToIdleSeconds="120"    
        timeToLiveSeconds="120"    
        overflowToDisk="true"    
        diskSpoolBufferSizeMB="30"    
        maxElementsOnDisk="10000000"    
        diskPersistent="false"    
        diskExpiryThreadIntervalSeconds="120"    
        memoryStoreEvictionPolicy="LRU"/>  

    <!-- The cache configuration for our Currency cache -->  
    <cache name="cachename"  
        maxElementsInMemory="3000"  
        eternal="false" 
        timeToIdleSeconds="120"  
        timeToLiveSeconds="120"  
        <persistence strategy="localTempSwap"/>
    </cache>  
</ehcache>  

and config.xml

 <ehcache:annotation-driven cache-manager="ehcache" />

<bean id="cacheManager" class="org.springframework.cache.ehcache.EhCacheCacheManager">
        <property name="cacheManager" ref="ehcache" />
        </bean>

<bean id="ehcache" class="org.springframework.cache.ehcache.EhCacheManagerFactoryBean" >
            <property name="configLocation" value="ehcache.xml" />
</bean>  

Answer 1

I hope your Account Type implements Serializable interface ? Can you post that as well?

Answer 2

I solved this by removing diskPersistent="false". diskPersistent="false" can't be used with decoratedCacheType= DecoratedCacheType.REFRESHING_SELF_POPULATING_CACHE
