ContentNegotiatingViewResolver + ExceptionResolver

[btpka3]

I'am newly studying REST && Spring MVC 3.

I have one question : How to handle exception when using ContentNegotiatingViewResolver ?

I found this is asked about two year ago, but still no satisfied solution：
http://forum.springsource.org/showthread.php?t=77417

The one method I can use now is :
ContentNegotiatingViewResolver + @ExceptionHandler

but @ExceptionHandler is not so convenience because：
1. Not accept ResponseEntity<T> as return value.
http://forum.springsource.org/showthread.php?t=100755
https://jira.springsource.org/browse/SPR-6008 （I'm using spring 3.0.5）
But, we still can use Map as return value and response.setStatus(int) instead.

2. I have to write multiple @ExceptionHandler method for each @Controller class, unless using super class for this.



------------------------------------------------------------------------------
I still tried this :
ContentNegotiatingViewResolver + SimpleMappingExceptionResolver

  <bean class="org.springframework.web.servlet.handler.SimpleMappingExceptionResolver">
    <property name="order" value="1" />
    <property name="exceptionMappings">
      <props>
        <prop key="BusinessException">forward:/app/error/4XX</prop>
        <prop key="SystemException">forward:/app/error/5XX</prop>
      </props>
    </property>
    <property name="defaultErrorView" value="/error/5XX"/>
  </bean>
  <bean class="org.springframework.web.servlet.view.ContentNegotiatingViewResolver" >
    <property name="order" value="0" />
    <property name="defaultContentType" value="application/json" />
    <property name="mediaTypes">
      <map>
        <entry key="xml" value="application/xml" /> 
        <entry key="json" value="application/json" />
      </map>
    </property>
    <property name="defaultViews">
      <list>
        <ref bean="xmlMarshallView" /> 
        <ref bean="mappingJacksonJsonView" />
      </list>
    </property>
  </bean>

But, I failed. By 《Spring Framework Reference Documentation 3.0》 15.5 Resolving views,
only UrlBasedViewResolver and its sub class can resolve "redirect:" and "forward:" prefix.
Actually， it seems ContentNegotiatingViewResolver does not concern the view names.

So , What is the best practice about Exception Handling with REST and Content Negotiation ? (Ask again, )
Is ContentNegotiatingViewResolver can resolve "forward:" prefix in future?
