XML 中的 Hibernate 数据过滤器多对一映射文件

Question

我想知道如何在多对一映射中添加数据过滤器。

放置示例代码：

<hibernate-mapping>
   <class name = "Employee" table = "EMPLOYEE">
      
      <meta attribute = "class-description">
         This class contains the employee detail. 
      </meta>
      
      <id name = "id" type = "int" column = "id">
         <generator class="native"/>
      </id>
      
      <property name = "firstName" column = "first_name" type = "string"/>
      <property name = "lastName" column = "last_name" type = "string"/>
      <property name = "salary" column = "salary" type = "int"/>
      <many-to-one name = "address" column = "address" 
         class="Address" not-null="true"/>
         
   </class>

   <class name = "Address" table="ADDRESS">
      
      <meta attribute = "class-description">
         This class contains the address detail. 
      </meta>
      
      <id name = "id" type = "int" column = "id">
         <generator class="native"/>
      </id>
      
      <property name = "street" column = "street_name" type = "string"/>
      <property name = "city" column = "city_name" type = "string"/>
      <property name = "state" column = "state_name" type = "string"/>
      <property name = "zipcode" column = "zipcode" type = "string"/>
      
   </class>

</hibernate-mapping>

基本上，我想添加一个过滤器来获取居住在城市（例如：Chennai）的员工，

  <filter name="cityFilter" condition="city=:cityFilterParam)"/>

有人可以告诉我它是如何实现的吗？
