借助Ehcache缓存框架实现对页面的缓存Demo

本工程用于研究如何借助Ehcache缓存框架实现对页面的缓存 本工程编码方式：UTF-8 本工程开发工具：MyEclipse 说明： 1、ehcache.xml和ehcache.xsd两个文件可以在下在下载下来的名为“ehcache-core-x.x.x-distribution.tar.gz”压缩文件中找到 2、由于要实现Ehcache缓存页面，所以必须要添加“ehcache-web-2.0.4.jar” jar包，该jar包主要用于辅助Ehcache实现页面缓存 注意： 本web工程的发布不要使用Tomcat7，否则会出现如下异常： 2015-3-25 9:53:50 org.apache.catalina.loader.WebappClassLoader loadClass 信息: Illegal access: this web application instance has been stopped already. Could not load net.sf.ehcache.store.disk.DiskStore$KeySet. The eventual following stack trace is caused by an error thrown for debugging purposes as well as to attempt to terminate the thread which caused the illegal access, and has no functional impact. java.lang.IllegalStateException at org.apache.catalina.loader.WebappClassLoader.loadClass(WebappClassLoader.java:1600) at org.apache.catalina.loader.WebappClassLoader.loadClass(WebappClassLoader.java:1559) at net.sf.ehcache.store.disk.DiskStore.keySet(DiskStore.java:560) at net.sf.ehcache.store.disk.DiskStorageFactory$DiskExpiryTask.run(DiskStorageFactory.java:838) at java.util.concurrent.Executors$RunnableAdapter.call(Executors.java:441) at java.util.concurrent.FutureTask$Sync.innerRunAndReset(FutureTask.java:317) at java.util.concurrent.FutureTask.runAndReset(FutureTask.java:150) at java.util.concurrent.ScheduledThreadPoolExecutor$ScheduledFutureTask.access$101(ScheduledThreadPoolExecutor.java:98) at java.util.concurrent.ScheduledThreadPoolExecutor$ScheduledFutureTask.runPeriodic(ScheduledThreadPoolExecutor.java:181) at java.util.concurrent.ScheduledThreadPoolExecutor$ScheduledFutureTask.run(ScheduledThreadPoolExecutor.java:205) at java.util.concurrent.ThreadPoolExecutor$Worker.runTask(ThreadPoolExecutor.java:886) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:908) at java.lang.Thread.run(Thread.java:619) 相关jar包下载地址： Ehcache 对象、数据缓存：http://ehcache.org/downloads/destination?name=ehcache-core-2.5.2-distribution.tar.gz&bucket=tcdistributions&file=ehcache-core-2.5.2-distribution.tar.gz Web页面缓存：http://ehcache.org/downloads/destination?name=ehcache-web-2.0.4-distribution.tar.gz&bucket=tcdistributions&file=ehcache-web-2.0.4-distribution.tar.gz
