按照nutzbook中的讲解，在做17.集成Ehcache及DaoCache 这一部分时，老是报异常：

能指点下如何配置吗？

shiro.ini:

[main]
sha256Matcher = org.apache.shiro.authc.credential.Sha256CredentialsMatcher
nutzdao_realm = com.zhangwei.test.nutzbook.shiro.realm.NutDaoRealm
nutzdao_realm.credentialsMatcher = $sha256Matcher

authc = org.nutz.integration.shiro.CaptchaFormAuthenticationFilter
authc.loginUrl  = /user2/user3/login
logout.redirectUrl= /user2/user3/login

[urls]
/rs/*        = anon
/user2/user3/logout = logout
/user2/user3/error  = anon
/user2/user3/profile/active/mail = anon
/user2/user3/**     = authc

cacheManager = org.apache.shiro.cache.ehcache.EhCacheManager
cacheManager.cacheManagerConfigFile=classpath:ehcache.xml
nutzdao_realm.cacheManager = $cacheManager

#如果需要缓存shiro的Session,可以加入这些配置(不推荐)
#sessionDAO = org.apache.shiro.session.mgt.eis.EnterpriseCacheSessionDAO
#sessionManager.sessionDAO = $sessionDAO
#securityManager.sessionManager = $sessionManager
#
#securityManager.cacheManager = $cacheManager

ehcahe.js:

var ioc = {
        cacheManager : {
            type : "net.sf.ehcache.CacheManager",
            factory : "net.sf.ehcache.CacheManager#getCacheManager",
            args : ["nutz-book"] // 对应shiro.ini中指定的ehcache.xml中定义的name
        }
        /*      
        // 如果不需要shiro初始化的Ehcache, 使用下面的方式配置
        cacheManager : {
            type : "net.sf.ehcache.CacheManager",
            factory : "net.sf.ehcache.CacheManager#create"
        }
         */
};
