@Controller返回json使用@ResponseBody

@Controller 返回string 默认是返回view的名字，想要直接返回json则需要@ResponseBody

    @GetMapping("/map")
    @ResponseBody
    public java.util.Map<String,String> test(){
        java.util.Map<String,String> map = new HashMap<>();
        map.put("hello","hello");
        return map;
    }

@RestController返回页面

@RestController默认返回json，想要返回页面则需要方法体返回ModelAndView

    @GetMapping("foo")
    public ModelAndView foo(){
        ModelAndView modelAndView = new ModelAndView();
        modelAndView.setViewName("foo/index.html");
        return modelAndView;
    }
