        String name = scanner.next();
        System.out.println("请输入密码：");
        String password = scanner.next();

        Map<String, String> map = new HashMap<>();
        map.put("222", "222");
        map.put("1", "1");
        map.put("2", "3");
        Set<Entry<String, String>> en = map.entrySet();
        for (Entry<String, String> entry : en) {
            if (name.equals(entry.getKey()) && password.equals(entry.getValue())) {
                System.out.println("登录成功");
                break;
            } else {
                System.out.println("用户名错误，请确认账户和密码后再输入");
                //shixian();

问题出现在你的for循环中
修改为:

 public static void shixian() {

        Scanner scanner = new Scanner(System.in);
        System.out.println("请输入账号：");
        String name = scanner.next();
        System.out.println("请输入密码：");
        String password = scanner.next();

        Map<String, String> map = new HashMap<>();
        map.put("222", "222");
        map.put("1", "1");
        map.put("2", "3");
        Set<Entry<String, String>> en = map.entrySet();

        boolean isTrue=false;
        for (Entry<String, String> entry : en) {
            if (name.equals(entry.getKey()) && password.equals(entry.getValue())) {
                isTrue=true;
                break;
            } 
        }

        System.out.println(isTrue?"登陆成功":"登陆失败");

    }
