Error validation message format Spring boot

i am new using Java and Spring boot, im trying to validate a json input that will be stored in DB, the validation is doing well, the problem is the response format, i think it is not readable for a client as Angular JS, in need to know how to change the output format from this :

{
"error": {
    "code": 400,
    "message": "Validation failed for classes [com.company.customerhelpcenter.domain.Ticket] during persist time for groups [javax.validation.groups.Default, ]\nList of constraint violations:[\n\tConstraintViolationImpl{interpolatedMessage='Descripción no puede ser null', propertyPath=description, rootBeanClass=class com.company.customerhelpcenter.domain.Ticket, messageTemplate='Descripción no puede ser null'}\n\tConstraintViolationImpl{interpolatedMessage='not a well-formed email address', propertyPath=email, rootBeanClass=class com.company.customerhelpcenter.domain.Ticket, messageTemplate='{org.hibernate.validator.constraints.Email.message}'}\n\tConstraintViolationImpl{interpolatedMessage='Número de teléfono no puede ser null', propertyPath=phone, rootBeanClass=class com.company.customerhelpcenter.domain.Ticket, messageTemplate='Número de teléfono no puede ser null'}\n]"
}}

to this

{
"error": {
    "description" : "Description cannot be null",
    "email": "Email cannot be null",
    "phone": "Phone cannot be null"
} }

This is my controller

@PostMapping
public ResponseEntity<?> create(@RequestBody Ticket ticket)
{
    return new ResponseEntity<>(this.ticketService.create(ticket), HttpStatus.CREATED);
}

Service:

public Ticket create(Ticket ticket)
{
    return this.ticketRepository.save(ticket);
}

Repository:

@Repository
public interface TicketRepository extends JpaRepository<Ticket, Integer>, Serializable
{}

Entity

@Entity
@Table(name = "ticket")
public class Ticket implements Serializable
{
    private static final long serialVersionUID = 1L;

    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    @Basic(optional = false)
    @Column(name = "id")
    private Integer id;

    @Basic(optional = false)
    @NotNull(message = "Descripción no puede ser null")
    @Size(min = 1, max = 255)
    @Column(name = "description")
    private String description;

    @Basic(optional = false)
    @NotNull(message = "Número de teléfono no puede ser null")
    @Size(min = 1, max = 20)
    @Column(name = "phone")
    private String phone;

    @Basic(optional = false)

    private String email;

    @Basic(optional = false)
    @NotNull
    @Column(name = "locked")
    private boolean locked;

    @JoinColumn(name = "ticket_type_id", referencedColumnName = "id")
    @ManyToOne(optional = false, fetch = FetchType.EAGER)
    @Exclude
    private TicketType ticketType;

    @OneToMany(mappedBy = "ticket")
    private Set<TicketHistory> ticketHistories = new HashSet<TicketHistory>();


    public Integer getId()
    {
        return this.id;
    }

    public String getDescription()
    {
        return this.description;
    }

    public String getPhone()
    {
        return this.phone;
    }

    public String getEmail()
    {
        return this.email;
    }

    public TicketType getTicketType()
    {
        return this.ticketType;
    }

    public boolean isLocked()
    {
        return this.locked;
    }

    public Set<TicketHistory> getTicketHistories()
    {
        return this.ticketHistories;
    }
}
