If you change the set value in your setter, Hibernate of course thinks it was modified. (the value returned by get is different than the one originally set by Hibernate)

thanks michael !

I change setPassword method in usr_ ,not use extends ,

from :

public void setPassword(String password) {
this.password = password;
}

to :

public void setPassword(String password) {
this.password = MD5.encode(password);
}


so the same result,

so i do it only in jsp files,

who can provide orther method to solve it?

thanks.
