HttpServletRequest获取REST风格参数

            // 获取Token
            String token = String.valueOf(restParamsMap.get("token"));

    public <K, V> Map<K, V> typeConversionMap(Object obj, Class<K> tClass, Class<V> vClass) {
        HashMap<K, V> result = new HashMap<>();
        if (obj instanceof Map<?, ?>) {
