Utilisateur user = (Utilisateur) request.getSession().getAttribute("user");
model.addAttribute("nbrMails", metierUtilisateur.listDesEmailsRecuNonLu(user.getIdUtilisateur()).size());
SujetForum sujet = metierSujetForum.findById(idSujet);
sujet.setMessagesForums(metierSujetForum.getListMessageForum(idSujet));

@OneToMany(mappedBy = "messageForum")
private Collection<PieceJointeForum> pieceJointeForums;
public MessagesForum(String message, Date dateDepotMessage, boolean messageCorrecte) {

this.message = message;
this.dateDepotMessage = dateDepotMessage;
this.messageCorrecte = messageCorrecte;
}
public MessagesForum() {

}
public Long getIdMessage() {
return idMessage;
}
public void setIdMessage(Long idMessage) {
this.idMessage = idMessage;
}
public String getMessage() {
return message;
}
public void setMessage(String message) {
this.message = message;
}
public Date getDateDepotMessage() {
return dateDepotMessage;
}
public void setDateDepotMessage(Date dateDepotMessage) {
this.dateDepotMessage = dateDepotMessage;
}
public boolean isMessageCorrecte() {
return messageCorrecte;
}
public void setMessageCorrecte(boolean messageCorrecte) {
this.messageCorrecte = messageCorrecte;
}
public SujetForum getSujetForum() {
return sujetForum;
}
public void setSujetForum(SujetForum sujetForum) {
this.sujetForum = sujetForum;
}
public Utilisateur getUtilisateur() {
return utilisateur;
}
public void setUtilisateur(Utilisateur utilisateur) {
this.utilisateur = utilisateur;
}
public Collection<PieceJointeForum> getPieceJointeForums() {
return pieceJointeForums;
}
public void setPieceJointeForums(Collection<PieceJointeForum> pieceJointeForums) {
