hook API系列---理解内核hook
<em>hook</em>分为应用层<em>hook</em> 和内核级<em>hook</em>, 应用层的<em>hook</em>在这里不做讨论。 内核级的<em>hook</em>分为 1. ssdt  <em>hook</em> 2. inline <em>hook</em>  关于这两种<em>hook</em>举个比较形象的例子。  假如我是第一次进入A2大楼去财务科找小赵办手续, 在A2门口有一张大楼位置表 写着: 321 : 财务科 我的办事顺序是: 1. 去位置表

关于O/R的问题,求大侠解救
例如:rn 数据库中有表news和newstype,news中有一列是newstype的ID,但是java对象中为了方便直接映射了news表,这个时候问题就来了,我想从java对象中获得news的所有数据做新闻列表,同时每条新闻前面显示新闻类型的名称,可是news中存的是newstype的ID是整型的,如果对每一个news记录的newstypeid做判断显示中文名称比较麻烦,有没有哪个<em>大侠</em>有好的在实际项目中使用的方法指点一下,谢谢。rn 如果修改java对象,添加newstype的名称属性,又无法与news简单映射,不知道如何解决是好。。。期待中
