原创 5.hql简单属性查询:总结
hibernate查询语言hql在hql中关键字不区分大小写，通常小写，类的名称和属性名称必须区分大小写1、简单属性查询【重要】 * 单一属性查询，返会属性结果集列表，元素类型和实体类中相应的类型一致 * 多个属性查询，多个属性查询返会对象数组，对象数组的长度取决于属性的个数 对象数组中元素的类型取决于属性在实体类中的类型 * 如果认为返会数组不够对象化，可以使用h

原创 5.LazyForClass 总结
hibernate的lazy策略可以使用在：* 标签上，可以取值：true/false* 标签上，可以取值：true/false,需要类增强工具，对字节码进行修改* /标签上,可以取值：true/false/extra* /单端关联标签上，可以取值：false/proxy/noproxylazy的概念：在真正使用某个对象的时候才正真的去创建，对于hibernate才会正真的
