// TODO Auto-generated method stub
SimplePrincipalCollection principals = new SimplePrincipalCollection(
principal, getName());
clearCachedAuthenticationInfo(principals);
}
protected void clearCachedAuthenticationInfo(PrincipalCollection principals) {
if (!CollectionUtils.isEmpty(principals)) {
Cache<Object, AuthenticationInfo> cache = getAvailableAuthenticationCache();这里的cache始终为空???
//cache instance will be non-null if caching is enabled:
if (cache != null) {
Object key = getAuthenticationCacheKey(principals);
cache.remove(key);
}
}
}
我想删除系统的缓存权限信息，但是没有有效果。而缓存是存在的，url拦截的时候是可以取到缓存的，相同的getAvailableAuthenticationCache()方法。
求高手赐教！！！！！！！
