package com.projet.pfe.entities;
import java.io.Serializable;
import javax.persistence.Entity;
import javax.persistence.Id;
import javax.persistence.IdClass;
import javax.persistence.JoinColumn;
import javax.persistence.ManyToOne;
#IdClass(ActiviteAF.class)
#Entity
public class ActiviteAF implements Serializable {
private static final long serialVersionUID = 1L;
#Id
#ManyToOne

private Activite activite;
#Id

#JoinColumn(name="idaf")
private AF fa;
private double montant;
public Activite getActivite() {
return activite;
}
public void setActivite(Activite activite) {
this.activite = activite;
}
public AF getFa() {
return fa;
}
public void setFa(AF fa) {
this.fa = fa;
}
public double getMontant() {
return montant;
}
public void setMontant(double montant) {
this.montant = montant;
}
public ActiviteAF(Activite activite, AF fa, double montant) {
super();
this.activite = activite;
this.fa = fa;
this.montant = montant;
}
public ActiviteAF() {
super();
}
}
this is my Repository
package com.projet.pfe.DAO;
import java.util.Collection;
import org.springframework.data.jpa.repository.JpaRepository;
import org.springframework.data.jpa.repository.Query;
import org.springframework.data.repository.query.Param;
import com.projet.pfe.entities.ActiviteAF;
public interface ActiviteAFRepository extends JpaRepository<ActiviteAF,Long> {
#Query("select af from ActiviteAF af where af.activite.idActivite like :x")
public Collection<ActiviteAF> activitebyid(#Param("x") Long id);
}
this is the Rest Controller
package com.projet.pfe.service;
import com.projet.pfe.DAO.AFRepository;
import java.util.Collection;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RestController;
import com.projet.pfe.DAO.ActiviteAFRepository;
import com.projet.pfe.DAO.ActiviteRepository;
import com.projet.pfe.entities.AF;
import com.projet.pfe.entities.Activite;
import com.projet.pfe.entities.ActiviteAF;
import org.springframework.web.bind.annotation.PathVariable;
#RestController
public class ActAFRestService {
#Autowired
private ActiviteAFRepository actafmet;
#Autowired
private ActiviteRepository actr;
#Autowired
private AFRepository afr;
#RequestMapping(value="/saveactaf/{idact}/{idaf}/{montant}",method=RequestMethod.POST)
public ActiviteAF save(#PathVariable(name="idact")long idact,#PathVariable(name="idaf")long idaf,#PathVariable(name="montant")double montant){
Activite a = new Activite();
AF af = new AF();
a = actr.findOne(idact);
af = afr.findOne(idaf);
ActiviteAF aaf = new ActiviteAF(a,af,montant);
return actafmet.save(aaf);
}
}

I find a solution , juste make a singel. Id and change the others to a simple annotation(forign keys) , this solution work but need a test( activite,af ) in the case of adding new object .
