【问题描述】：

我正在使用 Hibernate，我有这个查询：

List list = session.createQuery(" From as Project project where project.properties.pr_id = '4711' ").list();

还有这个项目的 hbm 文件：

<hibernate-mapping auto-import="true">
  <class dynamic-insert="true" dynamic-update="true" entity-name="Project" name="de.planta.server.hibernate.pojo.DynamicPojo" table="DT461">
  <dynamic-component name="properties">
   <property column="`DI041544`" default="0" name="miscel_pay_oblig" type="de.planta.server.hibernate.types.DefaultValueDoubleType" /> 
   <property column="`DI051881`" length="10" name="report_pls_report_id" type="de.planta.server.hibernate.types.DefaultValueStringType" /> 
   <property column="`DI059017`" length="8" name="active_process_phase" type="de.planta.server.hibernate.types.DefaultValueStringType" /> 
   <property column="`DI001001`" length="18" name="pr_id" type="de.planta.server.hibernate.types.DefaultValueStringType" />
         ...

还有这个错误信息，但是为什么？？？

【问题讨论】：

  • 这样对吗，第一个查询是From Project项目，而错误是From Project as project？
  • 我编辑文本，对不起
  • 同样的错误 org.hibernate.hql.internal.ast.QuerySyntaxException：意外令牌：p 靠近第 1 行，第 23 列 [来自项目 p，其中 p.properties.pr_id = '4711'
  • @trabzonlu1461 您的项目实体中的“属性”是什么？它是对另一个实体的对象引用吗？请分享您的实体
  • @ManjunathAnand 不是地图，我在问题中添加了 DynamicPojo

【解决方案1】：

我修复了错误：

<property name="hibernate.query.factory_class">org.hibernate.hql.internal.classic.ClassicQueryTranslatorFactory</property>

但我不知道为什么？ 谁能解释一下？
