Answer 1

試してみてください。

<evaluate expression="webFlowUtils.getFlashAttribute(externalContext, 'some')"/> 

と：

@Component 
public final class WebFlowUtils { 

    public Object getFlashAttribute(ExternalContext context, String attributeName) { 
     Map<String, ?> flashMap = RequestContextUtils.getInputFlashMap((HttpServletRequest) context.getNativeRequest()); 
     return flashMap != null ? flashMap.get(attributeName) : null; 
    } 
}
