我在EhCache引导过程中尝试从数据库加载数据时遇到异常。尝试从数据库加载数据时出现异常EhCache引导过程
如果我不从数据库加载数据，即从xyzBootstrapCacheLoaderFactory删除xyzTestResultFacade.loadxyzTestResultsFromDb();那么一切都很好。
我的猜测是Spring的数据库事务管理没有准备好，而我正在引导EhCache。
如果您认为需要其他文件，请让我知道。
xyzBootstrapCacheLoaderFactory：
import java.util.Properties;
import net.sf.ehcache.CacheException;
import net.sf.ehcache.Ehcache;

public class xyzBootstrapCacheLoaderFactory extends RMIBootstrapCacheLoaderFactory implements BootstrapCacheLoader {
Log log = LogFactory.getLog(xyzBootstrapCacheLoaderFactory.class);
@Autowired
xyzTestResultFacade xyzTestResultFacade;
@Override
public Object clone() throws CloneNotSupportedException {
return super.clone();
}
@Override

return false;
}
@Override

log.info("Bootstrapping the cache.");
xyzTestResultFacade.loadxyzTestResultsFromDb();
log.info("Bootstrapping cache completed successfully.");
}
@Override
public BootstrapCacheLoader createBootstrapCacheLoader(Properties properties) {
log.info("createBootstrapCacheLoader log ################################ " + this.hashCode());
return this;

<!--Default Cache configuration. These will applied to caches programmatically created through the CacheManager.
The following attributes are required:
maxElementsInMemory - Sets the maximum number of objects that will be created in memory
eternal - Sets whether elements are eternal. If eternal, timeouts are ignored and the
element is never expired.
overflowToDisk - Sets whether elements can overflow to disk when the in-memory cache
has reached the maxInMemory limit.
The following attributes are optional:
timeToIdleSeconds - Sets the time to idle for an element before it expires.
i.e. The maximum amount of time between accesses before an element expires
Is only used if the element is not eternal.
Optional attribute. A value of 0 means that an Element can idle for infinity.
The default value is 0.
timeToLiveSeconds - Sets the time to live for an element before it expires.
i.e. The maximum time between creation time and when an element expires.
Is only used if the element is not eternal.
Optional attribute. A value of 0 means that and Element can live for infinity.
The default value is 0.
diskPersistent - Whether the disk store persists between restarts of the Virtual Machine.
The default value is false.
diskExpiryThreadIntervalSeconds- The number of seconds between runs of the disk expiry thread. The default value
is 120 seconds.
