第一次使用jeecms系统，不知道其综版本有没有问题，但这个问题我弄了好几天了，
几乎把所有的源代码看了一遍，也没有找到解决的法。
最后，我在程序里加了一个vo把hibernate*对对象先加载到vo，然后再展现到模版才解决了问题。。
但这不是最好的解决方法。
程序测试时在后台打印的栏目id,name都没有问题；
输出到模版文件就报当前栏目的id为空，但是栏目的名称可以显示出来。
初步估计是freemaker在延时加载hibernate相关信息时报错。
Hibernate: select channel0_.channel_id as channel1_6_, channel0_.channel_path as channel2_6_, channel0_.lft as lft6_, channel0_.rgt as rgt6_, channel0_.priority as priority6_, channel0_.has_content as has6_6_, channel0_.is_display as is7_6_, channel0_.site_id as site8_6_, channel0_.model_id as model9_6_, channel0_.parent_id as parent10_6_ from jc_channel channel0_ where channel0_.site_id=? and (channel0_.parent_id is null) and channel0_.has_content=1 order by channel0_.priority asc, channel0_.channel_id asc
