JSF faire un CRUD dans un seul manageBean
Bonjour,
Je viens vers vous car j'ai un soucis sur comment anticiper la chose que je vais vous expliquer :
Comment est-ce que je peux fusionner ces deux classes en une seule ? C'est à dire "ArticleAddBean.java" + "ArticleReadBean.java" = "ArticleBean.java" tout en faisant la distinction de ce que je souhaite initialiser dans mon @PostConstrut init() (par exemple si je suis dans "monsite/views/add/article.xhtml" j'initialise tout ce qui concerne l'ajout d'un nouvelle article dans le init() mais je ne m'occupe pas du tout de ce qui concerne la lecture d'un article ? Je dois faire une condition genre if(monURL.contain("add/user")) User user = new User(); else ... ?
Voiçi un exemple de mes 2 classes ArticleAddBean.java et ArticleReadBean.java:

PS: si vous avez des remaques à faire sur mon code, je suis preneur.
Bien à vous.
