写个servlet 在 destroy方法里面 destroy cachemanager。 当然我没有遇到过你的问题，只是猜测。

: 用spring来管理试试

我已经尝试过这种做法了，但是还是删除不了。
貌似缓存还在使用ehcache.xml

本来就是交给spring管理了&&&&& spring+shiro+ehcache&&& 我快崩溃了....

类似的话题本帖子已过去太久远了，不再提供回复功能。shiro使用ehcache实现集群同步和session复制 - 坚持 - ITeye技术网站
博客分类：
一般情况下WEB应用集群的会话复制都是通过容器实现的，shiro权限框架中可以定义SessionDAO直接将session持久化到缓存中，这样只需要对缓存做集群就可以代替session的复制。
实现思路
1、用SessionDAO将session保存到ehcache缓存
2、配置ehcache的jgroups集群复制，如果集群服务器比较多，可升级到缓存服务器
思路很简单，但实现过程遇到不少问题，现在把过程及配置文件记录下来，避免忘记。
第一步将SessionDAO保存到ehcache缓存，这个步骤很简单，也没出什么问题，按照网上的例子很容易，下面是配置文件主要片段：
&!-- 主要是为了注入SessionDAO --&
&bean id="sessionManager" class="org.apache.shiro.web.session.mgt.DefaultWebSessionManager"&
&property name="sessionDAO" ref="sessionDAO"/&
&!-- SessionDAO用shiro提供的默认实现 --&
&bean id="sessionDAO" class="org.apache.shiro.session.mgt.eis.EnterpriseCacheSessionDAO"&
&!-- &property name="activeSessionsCacheName" value="shiro-activeSessionCache"/& --&
&property name="cacheManager" ref="shiroCacheManager" /&
&!-- 为了实现自己的用户权限 --&
&bean id="securityManager" class="org.apache.shiro.web.mgt.DefaultWebSecurityManager"&
&property name="realm" ref="userRealm"/&
&property name="sessionManager" ref="sessionManager"/&
&!-- By default the servlet container sessions will be used.
Uncomment this line
to use shiro's native sessions (see the JavaDoc for more): --&
&!-- &property name="sessionMode" value="native"/& --&
&!-- 自定义的用户权限，这里也需要用缓存，避免从数据库加载权限 --&
&bean id="userRealm" class="cn.ys.security.UserRealm"&
&property name="cacheManager" ref="shiroCacheManager"/&
&property name="userService" ref="securityService" /&
&property name="credentialsMatcher" ref="credentialsMatcher"&&/property&
&!-- 与spring ehcache集成 --&
&bean id="shiroCacheManager" class="cn.ys.security.ehcache.EhCacheManager"&
&property name="cacheManager" ref="ehcacheFactory"&&/property&
第二步遇到很多问题，网上资料比较少，对jgroups又不熟，下面是配置文件及我遇到的问题：
ehcache.xml
&!-- 缓存同步jgroup配置 --&

在网上查找的例子jgroups版本可能比较老，ehcache中的例子也一样，有些属性新的jgroups已经不认了，如start_port已经改成了bind_port，另外新版本jgroups增加了bind_addr，这样就可以直接指定ip地址绑定了，不需要在jvm上增加ipv4参数。
配置jgroups的几个需要理解的地方
1、jgroups的TCP的端口是自动分配自动发现的，同一台服务器上的多个实例不需要都配置到initial_hosts中，一个IP在initial_hosts中只需要定义一次，端口与bind_port保持一致
2、port_range是用于端口自动分配和自动发现用的，例如bind_port值为7800，当同服务上的第一个实例启动是使用7800端口，第二个实现启动时使用的是7801，最多只到7804
3、max_bundle_size不要太小，例子上该值只有64K，结果有时会现在无法复制的情况
4、当实例关闭再启动时，jgroups会认为是另一个host，原来的host如果不设置超时会一直存在，所以要注意设置keep_alive_time

唉,我就想看看 这个sessionDAO在代码中是怎么用的,这个sessionDAO很多方法都是空,难道需要自己实现吗?我用的是apache shiro提供的org.apache.shiro.web.session.mgt.DefaultWebSessionManager，不需要自己写代码

Mybatis与Ehcache整合可以提高性能，降低数据库压力。查询百度发现整合Mybatis与Ehcache其实非常简单的。
下载mybatis相关包与ehcache相关包
下载地址为：
作者下载的是
其中自带了
mybatis-ehcache-1.0.3.jar
ehcache-core-2.6.8.jar
slf4j-api-1.6.1.jar
将这三个包导入到项目的jar文件下，就可以使用ehcache功能了。当然前提是保证mybatis没有引入ehcache前，项目也能正常运行。
作者用的mybatis3.2版本，框架用了SpringMVC3.2等等。
现在就试试效果吧。
在Map文件中打开echached效果，account-mapper.xml文件内容如下，(有的文章说还需要配置ehcache.xml,作者测试根本不需要这个配置)：
