How can I solve the spring ambiguity problem in controller - spring

Question

**dispatcher-servlet.xml
<bean id="urlHandlerMapping" class="org.springframework.beans.factory.config.PropertiesFactoryBean">
<property name="properties">
<props>
<prop key="/testlistCustomer.htm">supplierController</prop>
</props>
</property>
</bean>
<bean id="customerController" class="com.debasish.spring.mvc.CustomerController">
</bean>
<bean id="supplierController" parent="customerController" class="com.debasish.spring.mvc.SupplierController">
</bean>
<bean id="viewResolver"
class="org.springframework.web.servlet.view.InternalResourceViewResolver" >
<property name="prefix">
<value>/WEB-INF/pages/</value>
</property>
<property name="suffix">
<value>.jsp</value>
</property>
</bean>
**CustomerController
public class CustomerController extends MultiActionController{
public ModelAndView testlistCustomer(HttpServletRequest request,
HttpServletResponse response) throws Exception {
return new ModelAndView("CustomerPage", "msg","list() method in CustomerControler");
}
}
**SupplierController
public class SupplierController extends CustomerController{
#Override
public ModelAndView testlistCustomer(HttpServletRequest request, HttpServletResponse response) throws Exception {
return new ModelAndView("CustomerPage", "msg","list() method in SupplierController ");
}
}
Spring framework version : 4.3.23.RELEASE
Server started and I'm able to access below url
http://localhost:8084/spring.mvc/testlistCustomer.htm
I am getting ambiguity exception When I am implementing similar functionality in annotation based application.
**dispatcher-servlet.xml
<!-- Provide support for component scanning -->
<context:component-scan base-package="spring.mvc.annotation" />
<!--Provide support for conversion, formatting and validation -->
<mvc:annotation-driven/>
<bean id="viewResolver"
class="org.springframework.web.servlet.view.InternalResourceViewResolver" >
<property name="prefix">
<value>/WEB-INF/pages/</value>
</property>
<property name="suffix">
<value>.jsp</value>
</property>
</bean>
**CustomerController
#Controller
#RequestMapping
public class CustomerController{
#GetMapping(path="/testlistCustomer.htm")
public ModelAndView testlistCustomer(HttpServletRequest request,
HttpServletResponse response) throws Exception {
return new ModelAndView("CustomerPage", "msg",
"list() method" );
}
}
**SupplierController
#Controller
public class SupplierController extends CustomerController{
#Override
public ModelAndView testalistCustomer(HttpServletRequest request,
HttpServletResponse response) throws Exception {
return new ModelAndView("CustomerPage", "msg",
"list() method in supplier controller");
}
}
When starting the server I am getting below exception
