<shiro:hasPermission name="user:delete"></shiro:hasPermission>如果没有缓存，一个Permission或者role判断要查询三次数据库-username查主体--主体查角色---角色查权限，这样对于数据库的压力太大，需要设置缓存。而且要注意到，在第一次查询时shiro就会多个Permission或者Role判断设置一次缓存，就是说，授权方法doGetAuthorizationInfo只走一次。
ehcache主包必须导入,shiro集成时CacheManager是没有实现的，主包中才有实现类EhCacheManager
@Bean
public CacheManager getCacheManager(){
CacheManager cacheManager = new EhCacheManager();
return cacheManager;
}Shiro集成web环境[Springboot]-认证与授权
