The hidden part of the query ID number

Mysql：

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

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

java code:

1, it may be 18 or ID 15

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, I like to use this

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