查询时隐藏部分身份证号

Mysql：

    select REPLACE(idcard, SUBSTR(mobile,4,12), '************') idcard from sys_users
    select insert(idcard,4, 12, '*************') idcard from sys_users ;

java代码：
1、身份证可能是18为或者15位

if (newTBProjectCorpInfo.getPersonidcard().length() == 18) {
            newTBProjectCorpInfo.setPersonidcard(newTBProjectCorpInfo.getPersonidcard().replaceAll("(\d{4})\d{10}(\d{4})", "$1****$2"));
        } else if (newTBProjectCorpInfo.getPersonidcard().length() == 15) {
            newTBProjectCorpInfo.setPersonidcard(newTBProjectCorpInfo.getPersonidcard().replaceAll("(\d{4})\d{8}(\d{4})", "$1****$2"));
        }

2， 对

User.setPersonidcard(User.getPersonidcard().replaceAll("(\w{4})\w{0,}(\w{4})", "$1****$2"));
