休眠简单查询，但不返回任何行

问题描述

| 以下查询不返回任何行 列出补救措施= session.createQuery（\“来自Remedy \”）。list（）; 没有错误，但补救措施列表中没有任何内容，并且表中有行。 我有2张桌子：remedy和remedyTranslation 我有以下地图文件： remedy.hbm.xml如下：

<?xml version=\"1.0\"?>
<!DOCTYPE hibernate-mapping PUBLIC \"-//Hibernate/Hibernate Mapping DTD 3.0//EN\"
         \"http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd\">
<hibernate-mapping>
  <class name=\"com.audiClave.Service.Remedy\" table=\"REMEDY\">
    <id column=\"REMEDY_ID\" name=\"remedy_id\" type=\"int\">
      <generator class=\"native\"/>
    </id>
    <property generated=\"never\" lazy=\"false\" name=\"name\">
      <column name=\"NAME\"/>
    </property>
    <set 
        name=\"remedyTranslations\" 
        lazy=\"true\"
        inverse=\"true\"
        cascade=\"save-update\">
  <key column=\"REMEDY_ID\"/>
  <one-to-many class=\"com.audiClave.Service.RemedyTranslation\"/>
    </set>
  </class>
</hibernate-mapping>

remedyTranslation.hbm.xml如下：

<?xml version=\"1.0\"?>
<!DOCTYPE hibernate-mapping PUBLIC \"-//Hibernate/Hibernate Mapping DTD 3.0//EN\"
        \"http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd\">

    </id>
    <many-to-one 
        name=\"remedy_id\" 
        column=\"REMEDY_ID\" 
        class=\"com.audiClave.Service.Remedy\" 
        not-null=\"true\"
        lazy=\"false\" />
    <property generated=\"never\" lazy=\"false\" name=\"name\">
        <column name=\"NAME\"/>
    </property>
    <property generated=\"never\" lazy=\"false\" name=\"language\">
        <column name=\"LANGUAGE\"/>
    </property>
</class>
</hibernate-mapping>

hibernate.cfg.xml：

<?xml version=\'1.0\' encoding=\'utf-8\'?>
