工作中需要根据身份证获取性别、出生日期及年龄，且要还要支持15位长度的身份证号码，网上搜索了一下，经过测试好像多少存在点问题，干脆自已写一个。

CertificateNo.java

/**

        boolean valid=Pattern.matches(myRegExpIDCardNo,certificateNo)||(certificateNo.length() == 17 && Pattern.matches(myRegExpIDCardNo,certificateNo.substring(0,15)));
        if(!valid){
            resultDTO.setStatueMessage("证件号码不规范!");
            return resultDTO;
        }
        int idxSexStart = 16;
