I am developing a rest service which recovers data from a database, on the backend side everything works well (I tested in postman it recovers the desired data as you can see in this photo):
but frontend level it does not work it gives me the following error:
yet I put the crossorigin in my controller, but it still does not work :(
here is the code for my controller:
package com.app.habilitation.controller;
import java.util.List;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.web.bind.annotation.CrossOrigin;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
import com.app.habilitation.entity.EmploiEntity;
import com.app.habilitation.service.EmploiService;
@RestController
@SpringBootApplication
@CrossOrigin(origins = "*")
@RequestMapping("/emploi")
public class EmploiController {
private EmploiService emploiService;
@Autowired
public EmploiController(EmploiService theemploiService) {
emploiService=theemploiService;
}
@CrossOrigin(origins = "*")
@GetMapping("/getall")
public List<EmploiEntity> getAll() {
return emploiService.findAll();
}
}
and this is my dao code :
package com.app.habilitation.dao;
import org.springframework.data.jpa.repository.JpaRepository;
import com.app.habilitation.entity.EmploiEntity;
public interface EmploiDao extends JpaRepository<EmploiEntity, Integer> {
}
and this is my entity code :
package com.app.habilitation.entity;
import java.sql.Date;
import java.util.List;
import javax.persistence.CascadeType;
import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.OneToMany;
import javax.persistence.Table;
@Entity
@Table(name="ORDO_DEP_P_EMPLOI")
public class EmploiEntity {
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
@Column(name="IDENTIFIANT")
private Integer id;
@Column(name="CODE")
private String code;
@Column(name="NOM")
private String nom;
@Column(name="DATEEFFET")

@Column(name="DATEFIN")
private Date datefin;
@Column(name="STATUT")
private String statut;
/*@OneToMany(mappedBy = "emploi", cascade = {CascadeType.DETACH, CascadeType.MERGE, CascadeType.PERSIST, CascadeType.REFRESH})
private List<UserEntity> users; */
public Integer getId() {
return id;
}
/* public List<UserEntity> getUsers() {
return users;
}
public void setUsers(List<UserEntity> users) {
this.users = users;
} */
public void setId(Integer id) {
this.id = id;
}
public String getCode() {
return code;
}
public void setCode(String code) {
this.code = code;
}
public String getNom() {
return nom;
}
public void setNom(String nom) {
this.nom = nom;
}
public Date getDateeffet() {
return dateeffet;
}
public void setDateeffet(Date dateeffet) {
this.dateeffet = dateeffet;
}
public Date getDatefin() {
return datefin;
}
public void setDatefin(Date datefin) {
this.datefin = datefin;
}
public String getStatut() {
return statut;
}
public void setStatut(String statut) {
this.statut = statut;
}
public EmploiEntity(Integer id, String code, String nom, Date dateeffet, Date datefin, String statut
) {
this.id = id;
this.code = code;
this.nom = nom;
this.dateeffet = dateeffet;
this.datefin = datefin;
this.statut = statut;
}
public EmploiEntity() {
}
@Override
public String toString() {
return "EmploiEntity [id=" + id + ", code=" + code + ", nom=" + nom + ", dateeffet=" + dateeffet + ", datefin="
+ datefin + ", statut=" + statut + "]";
}
}
this is my emploiService code :
package com.app.habilitation.service;
import java.util.List;
import com.app.habilitation.entity.EmploiEntity;
public interface EmploiService {
public List<EmploiEntity> findAll();
}
and this is my emploiServiceImpl :
package com.app.habilitation.service;
import java.util.List;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;
import com.app.habilitation.dao.EmploiDao;
import com.app.habilitation.entity.EmploiEntity;
@Service
public class EmploiServiceImpl implements EmploiService {
private EmploiDao emploiDao;
public EmploiServiceImpl(EmploiDao theEmploiDao) {
emploiDao=theEmploiDao;
}
@Override
@Transactional
public List<EmploiEntity> findAll() {
return emploiDao.findAll();
}
}
this is my component.html :
<div class="inscription">

can someone help me please ??
