将cfqueryparam与ColdFusion HQL查询一起使用

Cia*_*her 6 coldfusion hibernate hql cfquery

我正在使用HQL查询来获取一堆状态对象,如下所示:

<cfquery name="LOCAL.qStates" dbtype="hql">
    from States where countryID = #ARGUMENTS.countryID#
    order by name asc
</cfquery>

这很好用.但是,我很好,我想使用cfqueryparam,理想情况如下:

<cfquery name="LOCAL.qStates" dbtype="hql">
    from States 
    where countryID = <cfqueryparam cfsqltype="cf_sql_integer" value="#ARGUMENTS.countryID#" />
    order by name asc
</cfquery>

但这会引发错误:

[empty string] java.lang.NullPointerException at org.hibernate.impl.AbstractQueryImpl.verifyParameters(AbstractQueryImpl.java:353) at org.hibernate.impl.AbstractQueryImpl.verifyParameters(AbstractQueryImpl.java:323) at org.hibernate.impl.QueryImpl.list(QueryImpl.java:98) at coldfusion.orm.hibernate.HibernatePersistenceManager._executeHQL(HibernatePersistenceManager.java:822) at coldfusion.orm.hibernate.HibernatePersistenceManager.executeHQL(HibernatePersistenceManager.java:751) at ....

任何人都知道如何解决这个问题,并使用cfqueryparamcfqueryHQL查询?

提前致谢!

我已经查清了这件事的真相。

我的States对象设置如下:

  <cfcomponent output="false" persistent="true">

      <cfproperty name="stateID" type="numeric" fieldType="id" generator="identity" />
      <cfproperty name="name" type="string" />
      <cfproperty name="alphaCode" type="string" />


      <!--- Relationships --->
      <cfproperty name="country" type="array" fieldtype="many-to-one" cfc="Countries" fkcolumn="countryID" lazy="true" />



  </cfcomponent>

当使用<cfqueryparam>标签时,Hibernate 可能试图映射我作为数组传入的数字,但失败,从而引发错误。

如果我像这样从属性中删除关系:

<cfproperty name="countryID" type="numeric" />

...然后就可以了。
