当我在 EhCache 引导期间尝试从数据库加载数据时，遇到异常。
如果我不从数据库加载数据，即从 xyzBootstrapCacheLoaderFactory 中删除 xyzTestResultFacade.loadxyzTestResultsFromDb(); 那么一切都很好。
我的猜测是，当我引导 EhCache 时，Spring 的数据库事务管理还没有准备好。
如果您认为需要任何其他文件，请告诉我。
xyzBootstrapCacheLoaderFactory:

@Autowired

@Override

}
@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;
}
}

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.

Optional attribute. A value of 0 means that and Element can live for infinity.

diskPersistent - Whether the disk store persists between restarts of the Virtual Machine.

diskExpiryThreadIntervalSeconds- The number of seconds between runs of the disk expiry thread. The default value
is 120 seconds.

最佳答案
也许您有多个 CacheManager(也许是 Hibernate？)。 尝试向您的 ehcache 标记添加“name”属性(编辑:来自 ehcache.xml)。
关于java - 尝试从数据库白色 EhCache 引导过程加载数据时出现异常，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/35805256/
