在spring中替换bean属性列表中的一个类

我在基于SpringMVC的broadleaf工作

基于项目模块，在不同的xml文件中有3-4个blCustomPersistenceHandlers bean定义

<bean id="blCustomPersistenceHandlers" class="org.springframework.beans.factory.config.ListFactoryBean" scope="prototype">
        <property name="sourceList">
            <list>
                <bean class="org.broadleafcommerce.admin.server.service.handler.CategoryCustomPersistenceHandler"/>
                <bean class="org.broadleafcommerce.admin.server.service.handler.CustomerPasswordCustomPersistenceHandler"/>                
                <bean class="org.broadleafcommerce.openadmin.server.security.handler.AdminUserCustomPersistenceHandler"/>
                <bean class="org.broadleafcommerce.admin.server.service.handler.CustomerCustomPersistenceHandler"/>
                <bean class="org.broadleafcommerce.admin.server.service.handler.ProductCustomPersistenceHandler"/>
                <bean class="org.broadleafcommerce.admin.server.service.handler.ChildCategoriesCustomPersistenceHandler"/>
                <bean class="org.broadleafcommerce.admin.server.service.handler.SkuCustomPersistenceHandler"/>
            </list>
        </property>
    </bean>

下面是不同的xml文件

<bean id="blCustomPersistenceHandlers" class="org.springframework.beans.factory.config.ListFactoryBean" scope="prototype">
        <property name="sourceList">
            <list>
                <bean class="org.broadleafcommerce.cms.admin.server.handler.PageTemplateCustomPersistenceHandler"/>
                <bean class="org.broadleafcommerce.cms.admin.server.handler.StructuredContentTypeCustomPersistenceHandler"/>
                <bean class="org.broadleafcommerce.cms.admin.server.handler.SandBoxItemCustomPersistenceHandler"/>
                <bean class="org.broadleafcommerce.cms.admin.server.handler.PendingSandBoxItemCustomPersistenceHandler"/>
                <bean class="org.broadleafcommerce.cms.admin.server.handler.TimeDTOCustomPersistenceHandler"/>
                <bean class="org.broadleafcommerce.cms.admin.server.handler.RequestDTOCustomPersistenceHandler"/>
                <bean class="org.broadleafcommerce.cms.admin.server.handler.StructuredContentItemCriteriaCustomPersistenceHandler"/>
                <bean class="org.broadleafcommerce.cms.admin.server.handler.PageItemCriteriaCustomPersistenceHandler"/>
            </list>
        </property>
    </bean>

<bean id="blCustomPersistenceHandlers" class="org.springframework.beans.factory.config.ListFactoryBean"> <!-- scope="prototype" -->
        <property name="sourceList">
            <list>
                <bean class="com.mycompany.server.service.handler.HCProductCustomPersistenceHandler"/>
            </list>
        </property> 
    </bean>

上面的定义驻留在我们包含的jar文件中。 现在我想替换其中一个处理程序，例如ProductCustomPersistenceHandler

我需要更改有关该处理程序的一些功能，因此我在xml文件中更改了该处理程序，如下所示

<bean id="org.broadleafcommerce.admin.server.service.handler.ProductCustomPersistenceHandler"
        class="com.mycompany.server.service.handler.HCProductCustomPersistenceHandler" />

并将bean定义放入xml文件中

<bean id="blCustomPersistenceHandlers" class="org.springframework.beans.factory.config.ListFactoryBean" scope="prototype">
        <property name="sourceList">
            <list>
                <bean class="org.broadleafcommerce.cms.admin.server.handler.PageTemplateCustomPersistenceHandler"/>
                <bean class="org.broadleafcommerce.cms.admin.server.handler.StructuredContentTypeCustomPersistenceHandler"/>
                <bean class="org.broadleafcommerce.cms.admin.server.handler.SandBoxItemCustomPersistenceHandler"/>
                <bean class="org.broadleafcommerce.cms.admin.server.handler.PendingSandBoxItemCustomPersistenceHandler"/>
                <bean class="org.broadleafcommerce.cms.admin.server.handler.TimeDTOCustomPersistenceHandler"/>
                <bean class="org.broadleafcommerce.cms.admin.server.handler.RequestDTOCustomPersistenceHandler"/>
                <bean class="org.broadleafcommerce.cms.admin.server.handler.StructuredContentItemCriteriaCustomPersistenceHandler"/>
                <bean class="org.broadleafcommerce.cms.admin.server.handler.PageItemCriteriaCustomPersistenceHandler"/>
            </list>
        </property>
    </bean>

<bean id="blCustomPersistenceHandlers" class="org.springframework.beans.factory.config.ListFactoryBean"> <!-- scope="prototype" -->
        <property name="sourceList">
            <list>
                <bean class="com.mycompany.server.service.handler.HCProductCustomPersistenceHandler"/>
            </list>
        </property> 
    </bean>

我只是扩展这个处理程序并创建我的新处理程序，因为它只运行正在执行的核心处理程序，所以我想执行我的处理程序

但这是行不通的。 我不能
