Spring MVC + Mongotemplate
Bonjour,
Je cherche déséspérement depuis quelques jours une façon à intégrer une Arraylist dans un document Mongo.
Je vous explique :
Je veux arriver à stocker ce genre de document dans ma base mongo
Code:

"os" : "Windows Server",
"version" : "2008",
"functions" : [
"SFTP",
"FTPS",
"CFT",
"AD"
],
"interventions" : {
"title" : "Add User",
"doneBy" : "Ahmed",
"desc": "Some description here"
},
{
"title" : "Something lese",
"doneBy" : "test"
"desc": "Some description here"
}
} |
J'ai donc créé ce modèle :

Puis ce modèle :

public TextArea desc;
public String getTitle() {
return title;

public void setTitle(String title) {

this.doneAt = doneAt;
}
public TextArea getDesc() {
return desc;
}
public void setDesc(TextArea desc) {

Ensuite j'ai créé ce service :

| @Repository
public class EquipementService {
@Autowired
private MongoTemplate mongoTemplate;
public void addEquipement(EquipementModel equipement) {
if (!mongoTemplate.collectionExists(EquipementModel.class)) {
mongoTemplate.createCollection(EquipementModel.class);
}
mongoTemplate.insert(equipement);
}
public List<EquipementModel> listEquipement() {
return mongoTemplate.findAll(EquipementModel.class);
}
public void deleteEquipement(EquipementModel equipement) {
mongoTemplate.remove(equipement);
}
public void updateEquipment(EquipementModel equipement) {
mongoTemplate.insert(equipement);
}
} |
Et enfin j'ai créé ce controleur :
Code:

| @Autowired
private EquipementService equipementService;
@RequestMapping(value = "/home", method = RequestMethod.GET)
public String getEquipementList(ModelMap model) {
model.addAttribute("equipement", equipementService.listEquipement());
return "home";
}
@RequestMapping(value = "/add", method = RequestMethod.GET)
public String addEquipement(ModelMap model) {
model.addAttribute("getEquipementList", equipementService.listEquipement());
model.addAttribute("equipement", new EquipementModel());
return "newequipement";
}
@RequestMapping(value = "/save", method = RequestMethod.POST)
public String createEquipement(@ModelAttribute(value="equipement") @Valid EquipementModel equipement,BindingResult result, ModelMap model) {
if (result.hasErrors()) {
model.addAttribute("errors", result.getAllErrors());
return "newequipement";
}
equipementService.addEquipement(equipement);
return "redirect:home";
}
@RequestMapping(value = "/delete", method = RequestMethod.GET)
public String deleteEquipement(@ModelAttribute EquipementModel equipement, ModelMap model) {
equipementService.deleteEquipement(equipement);
return "redirect:home";
} |
Et donc le problème, lorsque je vais sur la webapp donc par exemple localhost:8080/home (ou /add)
J'ai ce message :

Ce qui est fort, c'est que lorsque je rafraichi la page, j'arrive bien sur la page comme si rien n'était, c'est uniquement lorsque je restart le serveur.
Si jamais j'enleve le modèle InterventionModel, tout fonctionne noramelement.
Est-ce que quelqu'un aurait une idée please?
Merci beaucoup.
