工具类之判断传入的参数是否为空

    public Boolean checkParamsNotNull(Object... params) {
        int a = 0;
        if (params != null && params.length > 0) {
            for (Object element : params) {
                if (element == null || element.toString().trim().length() == 0 ||
                    (element.toString().length() > 0 && element.toString().trim().length() == 0)) {
                    return false;
                }
                a++;
            }
            return a == params.length;
        }
        return false;
    }
