Début angularjs - springboot- spring data/rest

**ekremyilmaz** · 02/01/2015, 23h22

Bonjour,

Je débute un petit projet de dev avec angularjs - springboot- spring data/rest.

Avant tout, c'est tout nouveau pour moi angularjs

.

Je rencontre un petit problème lors de la persistance d'un objet.

J'ai un objet Customer, RefStatus

Savez-vous comment résoudre ce problème ?

En gros, j'ai une entité qui contient une clé étrangère. et j'aimerai l'enregistrer.

merci !

finalement, j'ai trouvé solution en créant un controller en java

Code :

	 @RequestMapping(value="/create/{name}/{status}",method = RequestMethod.POST,headers="Accept=application/json")
	 public Customer create(
			 @PathVariable String name,
			 @PathVariable String status){
		 Customer customer = new Customer();
		 customer.setName(name);
		 System.out.println("ici");
		RefStatus refStatus = refStatusRepository.findByCode(status);
		customer.setStatus(refStatus);
 
		return this.customerRepository.save(customer);
	 }

ça marche
