I have a Status Code 400in the frontend when i try to send a POST request with Angular 5 to Spring Boot Rest Controller.
Here is the Entity :
@Entity
public class Prestataires implements Serializable
{
@Id @GeneratedValue
private Long id;
private String nom;
private String email;
private String tele;
private String fax;
private String rib;
private String adresse;
private String taches;
private String photo;
@Lob
private byte[] file;
@ManyToOne
@JoinColumn(name="ID_PRESTATAIRES_TYPES")
private PrestatairesTypes prestatairesTypes;
//--------------Getters and Setters------------------------
//--------------Constructors-------------------------------
}
Here is the Second Entity:
@Entity
public class PrestatairesTypes implements Serializable
{
@Id @GeneratedValue
private Long id;
private String designation;
//-------------------Constructors----------------
//--------------Getters and Setters-------------------
//---------------------OneToMany---------------------
@OneToMany(mappedBy="prestatairesTypes")
private Collection<Prestataires> prestataires;
}
Here is the RestController :
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.data.domain.Page;
import org.springframework.data.domain.PageRequest;
import org.springframework.web.bind.annotation.CrossOrigin;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.RestController;
import org.springframework.web.multipart.MultipartFile;
import smart.syndic.dao.PrestatairesRepository;
import smart.syndic.entities.Prestataires;
@RestController
@CrossOrigin("*")
public class PrestatairesRestController
{
@Autowired
private PrestatairesRepository repository;
@RequestMapping(value="/prestataires",
method=RequestMethod.POST)
public Prestataires addVilles(Prestataires p,
@RequestParam("multipartFile") MultipartFile file)
{
byte[] rawFile = null;
try{
rawFile = file.getBytes();
}catch(Exception e){
e.printStackTrace();
}
p.setFile(rawFile);
return repository.save(p);
}
}
Here is The Model Prestataires in TypeScript :
export class PrestatairesModel
{
id:any;
nom:any;
email:any;
tele:any;
fax:any;
rib:any;
adresse:any;
taches:any;
photo:any;

prestatairesTypes:any;
}
Here is the model PrestatairesTypes in TypeScript:
export class PrestatairesTypeModel
{
id:any;
designation:any;
}
Here is the Angular Controller in TypeScript :
import { Component, OnInit } from '@angular/core';
