我正在使用带有磁盘存储持久性的缓存。 在应用程序的后续重新运行中,我遇到了以下错误:
net.sf.ehcache.store.DiskStore deleteIndexIfCorrupt
WARNING: The index for data file MyCache.data is out of date,
probably due to an unclean shutdown. Deleting index file MYCache.index
除了在应用程序中显式调用
net.sf.ehcache.CacheManager.shutdown()
之外,是否有其他方法可以解决这个问题?缓存配置:
<ehcache xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:noNamespaceSchemaLocation="ehcache.xsd"
updateCheck="true" monitoring="autodetect">
<diskStore path="C:\work"/>
<cacheManagerEventListenerFactory class="" properties=""/>
<cacheManagerPeerProviderFactory
class="net.sf.ehcache.distribution.RMICacheManagerPeerProviderFactory"
properties="peerDiscovery=automatic,
multicastGroupAddress=230.0.0.1,
multicastGroupPort=4446, timeToLive=1"
propertySeparator=","
/>
<cacheManagerPeerListenerFactory
class="net.sf.ehcache.distribution.RMICacheManagerPeerListenerFactory"/>
<defaultCache
maxElementsInMemory="1"
eternal="false"
timeToIdleSeconds="0"
timeToLiveSeconds="86400"
overflowToDisk="true"
diskSpoolBufferSizeMB="1"
maxElementsOnDisk="10000"
diskPersistent="true"
diskExpiryThreadIntervalSeconds="120"
memoryStoreEvictionPolicy="LFU"
/>
</ehcache>
重现问题的代码:
import java.util.ArrayList;
import java.util.List;
import net.sf.ehcache.Cache;
import net.sf.ehcache.CacheManager;
import net.sf.ehcache.Element;
public class CacheTest {
static CacheManager manager = new CacheManager(CacheTest.class
.getResource("ehcache.xml"));
static Cache cache;
public static void main(String[] args) {
// Get a default instance
manager.addCache("test");
cache = manager.getCache("test");
// Generate some junk so that the
// cache properly flushes to disk
// as cache.flush() is not working
List<String> t = new ArrayList<String>();
for (int i = 0; i < 1000; i++)
t.add(null);
// Oddly enough fewer elements
// do not persist to disk or give
// an error
for (int i = 0; i < 100000; i++) {
cache.put(new Element(i, t));
}
cache.flush();
if (cache.get("key1") == null) {
System.out.println("key1 not found in cache!");
cache.put(new Element("key1", "value1"));
}
System.out.println(cache.get("key1"));
}
}
