from EmployerCharges r1 where r1.routingCode.routingCode = ? and employer.employerId=? 

，其中以下是POJO类

<class name="com.greytip.wps.model.EmployerCharges" table="emp_RoutingCode_Charges" lazy="false"> 

    <id name="id" type="int" unsaved-value="0" > 
     <generator class="native"> 
      <param name="sequence">emp_RoutingCode_id_seq</param> 
     </generator> 
    </id> 
    <many-to-one name ="employer" class = "com.greytip.wps.model.Employer"/> 
    <many-to-one name ="routingCode" class = "com.greytip.wps.model.RoutingCode"/> 
    <property name="charges"/> 
</class>

启用Hibernate的配置显示SQL和格式SQL参数并且您可以在日志文件中看到正在触发的查询。

<property name="show_sql">true</property> 
<property name="format_sql">true</property> 
<property name="use_sql_comments">true</property>
