我定义了一个@modelattribute(“ mymodel”)

@modelattribute("mymodel")
MyModel mymodel() {
  MyModel mymodel = new MyModel();
  return mymodel;
 }
@RequestMapping(value = "/save",method = RequestMethod.POST)
public final void save(@modelattribute("mymodel") MyModel mymodel,final BindingResult binding,final HttpServletRequest request,final ModelMap modelMap) throws Exception {
    modelService.save(mymodel);
            // try to reset the model --> doesn't work!!!
    myModel = new MyModel();
}

问题是,即使我在save方法中重置了模型,但如果在保存操作之后重新加载页面并再次保存,该模型将包含先前myModel的所有值.

处理后如何重置？
