To Use redirect:/ in ModelAndView return type method, you are try following
要在 ModelAndView 返回类型方法中使用重定向：/，您可以尝试以下操作
ModelAndView modelAndView = new ModelAndView("redirect:/abc.htm");
modelAndView.addObject("modelAttribute" , new ModelAttribute());
return modelAndView;
You can also return home page using String returntype if you do not need any Model in home page
如果主页中不需要任何模型，也可以使用 String returntype 返回主页
@RequestMapping(value = "/home.htm", method = RequestMethod.GET)
public String homePage() {
return "home";
}

There are different ways to redirect but using Spring ModelView Object is simple
有多种重定向方式，但使用 Spring ModelView 对象很简单
@RequestMapping(value = "/redirecturl", method = RequestMethod.POST)
public ModelAndView methodPost() {
return new ModelAndView( "redirect:/login.html");
}
