如何在Spring SImpleFormController中发送自动提交？

Question

假设我有一个SimpleFormController：

import org.springframework.web.servlet.mvc.SimpleFormController;

public class MyForm extends SimpleFormController
{

    @Override
    protected Object formBackingObject(HttpServletRequest request) throws Exception
    {
        final MyBean bean = new MyBean();
        String data = request.getSession().getAttribute("data");
        if (data!= null)
             this.doSubmitAction(bean);
        return bean;
    }


    @Override
    protected ModelAndView handleRequestInternal(HttpServletRequest request,
        HttpServletResponse response) throws Exception
    {
        return super.handleRequestInternal(request, response);
    }

    @Override
    protected ModelAndView onSubmit(HttpServletRequest request,
        HttpServletResponse response, Object command, BindException errors)
        throws Exception
    {
        // do Stuff
    }
}

如何根据会话属性从控制器触发onSubmit() 。 从代码中，我尝试放置this.doSubmit()但不会触发onSubmit() 。 是否可以在控制器内部进行操作？ 基本上，我的测试首先触发handleRequestInternal ，然后触发“ formBackingObject”，但无法在内部触发“ onSubmit”。
