dao class

  @repository   @transactional   public class userdaoimpl implements userdao{  @autowired private sessionfactory sessionfactory;     @override @transactional public user getuserbyname(string username) {     // todo auto-generated method stub     user user = (user) sessionfactory.getcurrentsession().createquery(              "select u userentity u u.username = '' +         username + ''").uniqueresult();              return user; } 

service

   @service("customuserdetailsservice")     public class customuserdetailsservice implements userdetailsservice{  @autowired private userentitydao userentitydao;  @autowired private assembler assembler;  @override @transactional(readonly = true) public userdetails loaduserbyusername(string username)         throws usernamenotfoundexception {     // todo auto-generated method stub     userdetails userdetails = null;      userentity userentity = userentitydao.getuserbyname(username);      if (userentity == null)      throw new usernamenotfoundexception("user not found");      return assembler.builduserfromuser(userentity);     }}
