maven工程在eclipse中跑向cookie中添加值成功，部署到tomcat添加就不成功了

Question

项目是在用户登陆成功后，随即生成一个数，“token”作为键添加到cookie中，在eclipse中跑，用360，谷歌浏览器访问都能看到有这个cookie值，但是部署到远程tomcat服务器上，再访问就没有看到cookie值了
@RequestMapping(value="/user/login", method=RequestMethod.POST)

    //判断是否登录成功
    if(e3Result.getStatus() == 200) {
        String token = e3Result.getData().toString();
        //如果登录成功需要把token写入cookie
        CookieUtils.setCookie(request, response, "token", token);

    //根据用户名查询用户信息

    TbUser user = list.get(0);
    //判断密码是否正确
    if (!DigestUtils.md5DigestAsHex(password.getBytes()).equals(user.getPassword())) {

        return E3Result.build(400, "用户名或密码错误");
    }
    // 3、如果正确生成token。
    String token = UUID.randomUUID().toString();
    // 4、把用户信息写入redis，key：token value：用户信息
    
    user.setPassword(null);
    jedisClient.set("SESSION:" + token, JsonUtils.objectToJson(user));
    // 5、设置Session的过期时间
    jedisClient.expire("SESSION:" + token, SESSION_EXPIRE);
    // 6、把token返回
