ehcache.xml configure default cache

[hqtc123]

参考第十二章的时候，项目运行出现了异常：
org.springframework.beans.MethodInvocationException: Property 'cacheManager' threw exception; nested exception is org.apache.shiro.cache.CacheException: net.sf.ehcache.CacheException: Caches cannot be added by name when default cache config is not specified in the config. Please add a default cache config in the configuration.

不知道是不是版本的问题。ehcache官方文档2.4版的说要在配置文件中加上一个 defaultcache ：
http://ehcache.org/documentation/faq#what-does-the-following-error-mean-caches-cannot-be-added-by-name-when-default-cache-config-is-not-specified-in-the-config-please-add-a-default-cache-config-in-the-configuration

@hqtc123 试试最新版本的ehcache?
