即使这是一篇老文章，我也想分享我的解决方案.

Even though, it is an old post, I wanted to share my solution.

您实际上并不需要ModelAndView mv方法参数.只需将其删除.

You don't actually need ModelAndView mv method parameter. Just remove it.

以字符串形式返回视图名称:

Return view name as string:

@RequestMapping("/greeting")
public String greeting(@RequestParam(value="name", required=false, defaultValue="World") String name, Model model) {
    model.addAttribute("name", name);

    return "greeting";
}
