Java Spring 添加 model 到 ModelAndView 抛出 StackOverflowException

Question

将 model 添加到 modelandview 时，有什么方法可以防止 StackOverflowException？

I have a method that returns a modelandview but I've seen that if I try to add model to modelandview it throws and StackOverflowException because Model already has modelandview, is there any way to add it without need to remove modelandview from model first?

    ((BindingAwareModelMap) model).remove("org.springframework.validation.BindingResult.modelAndView");
    ((BindingAwareModelMap) model).remove("modelAndView");
    modelAndView.addObject(model);
    return modelAndView;

Answer 1

当您使用ModelAndView时， Spring 不希望您手动创建Model 。

Spring 希望您将 model 的属性设置为直接在 model ModelAndView中包含的模型中。

所以应该是

modelAndView.getModel().put("attribute1", object1);
modelAndView.getModel().put("attribute2", object2);
