hibernate查询

Question

String queryString = "from XlrzFJ as t ";
我要查询 XlrzFJ 所有类 可是一个属性 infor_id 已经用于mant-to-one
name="xlrzInfor"
class="cn.hnedu.hnbys.database.XlrzInfor"
cascade="none"
outer-join="auto"
update="true"
insert="true"
access="property"
column="infor_id"
not-null="true"
/>
所以XlrzFJ.hbm.xml就没有

这一列的配置
查出来的XlrzFJ infor_id=null 要如何才能查出来 数据库里infor_id 有值

可以有这一列的配置的.

你配置没对吧.

下面的代码运行了.是能得到外键值的.

[code="java"]<?xml version="1.0" encoding="utf-8"?>

name="xlrzinfor"
class="com.Xlrzinfor"
cascade="none"
outer-join="auto"
update="true"
insert="true"
access="property"
column="infor_id"
not-null="true"
/>

</class>
