当向前台传递信息有时候会因为中文的编码问题产生乱码，这样我们可以通过进行转码解决，同时可以在springmvc中进行配置方法来解决

 @RequestMapping(value = "/register",produces="text/html;charset=UTF-8", method = {RequestMethod.POST})
    @ResponseBody
    public String reg(Model model, @RequestParam("name") String name,
                      @RequestParam("password") String password,
                      @RequestParam(value = "rember", defaultValue = "0") int rememberme,
                      HttpServletResponse response) {
        
        try {
            Map<String, Object> map = userService.register(name, password);
            if (map.containsKey("ticket")) {
                Cookie cookie = new Cookie("ticket", map.get("ticket").toString());
                cookie.setPath("/");
                if (rememberme > 0) {
                    cookie.setMaxAge(3600 * 24 * 5);
                }
                response.addCookie(cookie);
                return HisUtil.getJSONString(0, "注册成功");
            } else {

                System.out.println(map);
                return HisUtil.getJSONString(1, map);
            }

        } catch (Exception e) {
            return HisUtil.getJSONString(1, "注册异常");
        }
    }

只需要在requestmaping中加入produces="text/html;charset=UTF-8"
