Hello everyone, I try to force the passwords to be strong, then I edit the file WEB-INFapplicationContext.xml to change the default line <property name="allowedPasswordPattern" value="^.*$"></property> with <property name="allowedPasswordPattern" value="^(?=.*[a-z])(?=.*[A-Z])(?=.*[0-9])(?=.*[=.% !@#$^&])(?=.{9,})"></property> Then force a password of length greater than 8, at least one lowercase, one uppercase, one digit and one special character (=,% !@#$^&). However it doesn't work for me. How can I solve that? Thank you very much in advance!
