解决方法

我之前用的@RestController注解,而@RestController这个控制器返回数据而不是视图，改成@Controller 就好了(以下是修改后的)

@Controller

public class WebController {

    @Autowired

    private WxService service;

    @Autowired

    private HttpServletRequest request;

    @Autowired

    private HttpServletResponse response;

    /**

     * 获取授权的用户信息

     * @return

     */

    @GetMapping("/usr")

    public String getUsr() {

        try {

            String code = request.getParameter("code");

            //获取accesstoken的地址

            String url = "https://api.weixin.qq.com/sns/oauth2/access_token?appid=APPID&secret=SECRET&code=CODE&grant_type=authorization_code";

            url = url.replace("APPID", "wx3da4b30dadc22ff7").replace("SECRET", "2e132b85894583981d8410043443b766").replace("CODE", code);

            String result = Util.get(url);

            //获取result里面的token

            JSONObject jsonObject = new JSONObject(result);

            String at = jsonObject.getString("access_token");

            String openId = jsonObject.getString("openid");

            //拉取用户基本信息

            url = "https://api.weixin.qq.com/sns/userinfo?access_token=ACCESS_TOKEN&openid=OPENID&lang=zh_CN";

            url = url.replace("ACCESS_TOKEN", at).replace("OPENID", openId);

            result = Util.get(url);

            JSONObject usr = new JSONObject(result);

            User user = new User(usr.getString("openid"), usr.getString("nickname"), Integer.parseInt(usr.getString("sex")), usr.getString("language"), usr.getString("city"), usr.getString("headimgurl"), usr.getString("privilege"));

            return "index";

        } catch (JSONException e) {

            e.printStackTrace();

            return null;

        }

    }

}
