如何在spring-boot中获取实体的所有元素？

Question

I'm sending a GET request from angular5 to spring-boot to get all the elements of the entity Contrat below .

This is the entity :

@Entity
@Data
@AllArgsConstructor
@NoArgsConstructor
public class Contrat implements Serializable{

        @Id @GeneratedValue
        private Long id;
        private Date dateDebut ;
        private Date dateFin ;
        @ManyToOne
        @JoinColumn(name = "Id_Project")
        @JsonBackReference(value="projet-contrat")
        private Project project;

        @ManyToOne
        @JoinColumn(name = "Id_AppUser")
        @JsonBackReference(value="appuser-contrat")
        private AppUser appUser;
}

This is the repository :

  public interface ContratRepo extends JpaRepository<Contrat,Long> {

    @Query("select from Contrat c where c.appUser = :userApp")
    public Page<Contrat> chercherContrat(@Param("userApp") AppUser userApp  
   , Pageable pageable);

   }

In Angular5 the console.log(data) returns this result for exemple:

 {id: 1, dateDebut: 1526083200000, dateFin: 1526083200000} 

So as you can see there is not the project element (that i need in front-end) .

I want to show in angular the contrat elements plus some information of the project related to .

Any idea ?

您可以使用PagingAndSorting存储库代替jpaRepositiry来通过findAll api获取所有相关实体的详细信息。
