hibernate ehcache timeToLiveSeconds not working - spring

Question

I am using query cache in Spring Data, Hibernate, ehcache environment. The ehcache dependency is compile 'org.hibernate:hibernate-ehcache:3.3.1.GA'
The ehcache dependency tree is
+--- org.hibernate:hibernate-ehcache:3.3.1.GA
| +--- org.hibernate:hibernate-core:3.3.1.GA -> 3.6.6.Final (*)
| +--- net.sf.ehcache:ehcache:1.2.3
| | \--- commons-collections:commons-collections:2.1 -> 3.2.1
| \--- org.slf4j:slf4j-api:1.5.2 -> 1.6.5
I have a resources/ehcache.xml with timeToLiveSeconds configured to 5 minutes.
<?xml version="1.0" encoding="UTF-8"?>
<ehcache xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:noNamespaceSchemaLocation="http://ehcache.org/ehcache.xsd">
<diskStore path="/home/prayag/cache_"/>
<defaultCache
eternal="false"
maxElementsInMemory="1000"
overflowToDisk="true"
diskPersistent="true"
timeToLiveSeconds="300"
diskExpiryThreadIntervalSeconds="300"
memoryStoreEvictionPolicy="LRU"
/>
</ehcache>
Caching works but after 5 minutes, cache doesn't get auto-flushed and no new changes are shown.
Not even following code to remove cache works.
import net.sf.ehcache.Cache;
import net.sf.ehcache.CacheManager;
CacheManager cacheManager = CacheManager.getInstance();
String[] names = cacheManager.getCacheNames();
for (String name : names) {
if (name.equals("merchantServices")) {
Cache cache = cacheManager.getCache(name);
cache.removeAll();
}
}
My Caching configuration(jpa-context.xml) with cacheName merchantServices is
<?xml version="1.0" encoding="UTF-8"?>

Caching files at diskStore are as below,

Basically you are facing ehcache autoflush problem which is discussed over here.
Problem with auto flush in ehcache
There is a solution to your problem which has been discussed over here. hope it helps you coz I aint an ehcache pro.. :P
