有没有办法将存储在字符串中的 LDAP 属性用作 RegEx 模式？
我在想这样的事情：
PASSWORD_WITH_LDAP_ATTRIBUTE = Pattern.compile(userid + "|" + ssn + "|" + bdate + "|" + empNo + "|" + telNo);
我已经试过这个了。在我输入的任何字符串中，正则表达式总是找到匹配项，即使它不是明确的匹配项。
这是可能的还是我在冒险尝试不可能的事情？
这是整个方法：
private static Pattern PASSWORD_WITH_LDAP_ATTRIBUTE = null;
private boolean checkForLdapAttributes(final String newPassword) throws LDAPException{
LoggingEnt loggingEnt = new LoggingEnt();
String userid = loggingEnt.getUseridCode();
String ssn = loggingEnt.getSocialSecurityNumber();
String bdate = loggingEnt.getBirthDate();
String empNo = loggingEnt.getEmployeeNumber();
String telNo = loggingEnt.getTelephoneNumber();
PASSWORD_WITH_LDAP_ATTRIBUTE = Pattern.compile(userid + "|" + ssn + "|" + bdate + "|" + empNo + "|" + telNo);
matcher = PASSWORD_WITH_LDAP_ATTRIBUTE.matcher(newPassword);
if(PASSWORD_WITH_LDAP_ATTRIBUTE.matcher(newPassword).find()){
isPasswordAccepted = false;
loggingEnt.setMsg1("You cannot use any of your Username, Social Security No., Birthdate, Employee No., and Telephone No. as password.");
throw new LDAPException("Invalid password combination for " + userid, LDAPException.INVALID_CREDENTIALS);
} else {
loggingEnt.setMsg1("Password accepted.");
isPasswordAccepted = true;
}
return matcher.matches();
}
