如何通过配置自动实现ValueList中hql语句的整型参数转换

通过valuelist的queryMap传递过来的参数默认都为string类型，在valuelist配置文件的hql中，如果直接将该值赋给整型的字段会报错。一般我们会在hql中利用转型函数来进行处理，如下：
复制代码 代码如下:
<entry key="areasInfoAdapter">
       <bean  parent="abstractHibernate30Adapter">
                   <property name="defaultNumberPerPage"><value>19</value></property>
                     <property name="statementBuilder"><ref bean="statementBuilderHql"/></property>
                      <property name="defaultSortColumn"><value>id</value></property>
                      <property name="defaultSortDirection"><value>desc</value></property>
                      <property name="hql">
                          <value>
                              from com.berheley.hcms.persistence.model.TBaseAreas as tb
                              where tb.status='1'
                               /~hId  : and tb.hId  = to_number{hId}  ~/
                               /~oId  : and tb.oId  = to_number{oId}  ~/
                               order by tb.code asc
                          </value>
                      </property>
                      <property name="defaultFocusPropertyObjectAlias"><value>vo</value></property>
                      <property name="maxRowsForFocus"><value>160000</value></property>           
                      <property name="removeEmptyStrings"><value>true</value></property>
                  </bean>
                </entry>

该方法比较麻烦，在所有的整型字段地方都需要添加函数处理，并且进行数据库迁移时会出现函数不兼容的问题。可以利用ValueList配置来对整型的字段进行统一设置，valuelist在拼装sql前会对配置好的参数进行转型。如下：
复制代码 代码如下:
<bean id="integerSetterHql" class="net.mlw.vlh.adapter.hibernate3.util.setter.IntegerSetter"></bean>
 <bean id="statementBuilderHql" class="net.mlw.vlh.adapter.hibernate3.util.StatementBuilder">
    <property name="setters">
     <map>
      <entry key="uId"><ref bean="integerSetterHql"/></entry>
                                     <entry key="oId"><ref bean="integerSetterHql"/></entry>
     </map>
    </property>
   </bean>
