问题是DEBUG之后我也不清楚应该看哪里！ DEBUG的信息实在是太多，很难看全！ 能否给个实例，指出那里显示了使用了二级缓存！
对Log4J进行分类分级一下，我的如下，你可以进行修改：
代码 log4j.threshold = ALL log4j.rootLogger = ALL # log4j.category.org.springframework debug,FrameWorkSpring log4j.category.org.hibernate debug,FrameWorkHibernate log4j.category.net.sf.ehcache debug,FrameWorkEhCache log4j.appender.FrameWorkSpring org.apache.log4j.DailyRollingFileAppender log4j.appender.FrameWorkSpring.File ${system.logPath}/FrameWorkSpring.log log4j.appender.FrameWorkSpring.DatePattern yyyy-MM-dd'.log' log4j.appender.FrameWorkSpring.layout org.apache.log4j.PatternLayout log4j.appender.FrameWorkSpring.layout.ConversionPattern [%c]-[%p] %m%n log4j.appender.FrameWorkSpring.append false log4j.appender.FrameWorkHibernate org.apache.log4j.DailyRollingFileAppender log4j.appender.FrameWorkHibernate.File ${system.logPath}/FrameWorkHibernate.log log4j.appender.FrameWorkHibernate.DatePattern yyyy-MM-dd'.log' log4j.appender.FrameWorkHibernate.layout org.apache.log4j.PatternLayout log4j.appender.FrameWorkHibernate.layout.ConversionPattern [%c]-[%p] %m%n log4j.appender.FrameWorkHibernate.append false log4j.appender.FrameWorkEhCache org.apache.log4j.DailyRollingFileAppender log4j.appender.FrameWorkEhCache.File ${system.logPath}/FrameWorkEhCache.log log4j.appender.FrameWorkEhCache.DatePattern yyyy-MM-dd'.log' log4j.appender.FrameWorkEhCache.layout org.apache.log4j.PatternLayout log4j.appender.FrameWorkEhCache.layout.ConversionPattern [%c]-[%p] %m%n log4j.appender.FrameWorkEhCache.append false <script type="text/javascript">render_code();</script>
可以看到命中的信息
代码 [net.sf.ehcache.store.MemoryStore]-[DEBUG] xxx.xxx.XyzCache: xxx.xxx.XyzMemoryStore hit for xxx.xxx.Xyz#8 <script type="text/javascript">render_code();</script>
没命中的信息：
代码 [net.sf.ehcache.Cache]-[DEBUG] xxx.xxx.Xyz cache - Miss<script type="text/javascript">render_code();</script> 大概是这样子的，可以继续进行观察它的详细log信息再做分析。
增加一些信息：
EhCache初始化的信息
代码 [net.sf.ehcache.CacheManager]-[DEBUG] Configuring ehcache from classpath.

EhCache开始工作的信息
代码 [net.sf.ehcache.store.DiskStore]-[DEBUG] Deleting data file xxx.xxx.Xyz.data [net.sf.ehcache.store.MemoryStore]-[DEBUG] Initialized net.sf.ehcache.store.LruMemoryStore for xxx.xxx.Xyz [net.sf.ehcache.store.LruMemoryStore]-[DEBUG] xxx.xxx.Xyz Cache: Using SpoolingLinkedHashMap implementation [net.sf.ehcache.Cache]-[DEBUG] Initialised cache: xxx.xxx.Xyz
