ich bin zwei Anwendungen mit Spring 3. Die erste ist Rest API und die zweite ist ein Client.Der Client muss eine Reservierung erstellen. Ich bekomme 400 Bad Request Fehler, bitte helfen.400 Schlechte Anfrage mit RestTemplete und postForObject
Die Klasse Reservierung in der Client-Anwendung:
package ma.ensias.agencecentrale.entities;
import java.io.Serializable;
import java.util.Collection;
import javax.persistence.CascadeType;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.JoinColumn;
import javax.persistence.JoinTable;
import javax.persistence.ManyToMany;
import javax.persistence.ManyToOne;
import javax.persistence.Table;
import org.codehaus.jackson.annotate.JsonIgnore;
import org.codehaus.jackson.annotate.JsonIgnoreProperties;
import org.codehaus.jackson.annotate.JsonProperty;
@JsonIgnoreProperties(ignoreUnknown=true)
@Entity
@Table(name="reservations")
public class Reservation implements Serializable{
@Id
@GeneratedValue(strategy=GenerationType.IDENTITY)
private Long idReservation;
private String date;
@ManyToOne
@JoinColumn(name="id_utilisateur")
private Utilisateur utilisateur;
@JsonIgnore
@ManyToMany(cascade=CascadeType.ALL)
@JoinTable(name="passager_reservation", [email protected](name="id_reservation"), [email protected](name="id_passager"))
private Collection<Passager> passagers;
@JsonIgnore
@ManyToMany(cascade=CascadeType.ALL)
@JoinTable(name="vol_reservation", [email protected](name="id_reservation"), [email protected](name="id_vol"))
private Collection<Vol> vols;
// Contructor without fields
public Reservation() {
super();
}
// contructor with date attribute
public Reservation(String date) {
super();
this.date = date;
}
// ----------------------- Getters and setters-------------------------------
public String getDate() {
return date;
}
public void setDate(String date) {
this.date = date;
}
@JsonProperty(value="client")
public Utilisateur getUtilisateur() {
return utilisateur;
}
public void setUtilisateur(Utilisateur utilisateur) {
this.utilisateur = utilisateur;
}
public Collection<Vol> getVols() {
return vols;
}
public void setVols(Collection<Vol> vols) {
this.vols = vols;
}
public Long getIdReservation() {
return idReservation;
}
}
der Rest Auftraggeber:
// ----------------- - Erstellen Sie eine Reservierung --------------------------------------------- -----------
@RequestMapping("/ajouterReservation")
private static void ajouterReservation(Reservation reservation) {
RestTemplate restTemplate = new RestTemplate();
Reservation addedRes = restTemplate.postForObject(REST_SERVICE_URI,reservation, Reservation.class);
}
Und die Klasse Reserva tion in Anbieter App:
package ma.ensias.agencevoyage.entities;
import java.io.Serializable;
import java.util.Collection;
import javax.persistence.CascadeType;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.JoinColumn;
import javax.persistence.JoinTable;
import javax.persistence.ManyToMany;
import javax.persistence.ManyToOne;
import javax.persistence.Table;
import org.codehaus.jackson.annotate.JsonIgnore;
import org.codehaus.jackson.annotate.JsonIgnoreProperties;
import org.codehaus.jackson.annotate.JsonProperty;
@JsonIgnoreProperties(ignoreUnknown=true)
@Entity
@Table(name="reservations")
public class Reservation implements Serializable{
@Id
@GeneratedValue(strategy=GenerationType.IDENTITY)
private Long idReservation;
private String date;
@ManyToOne(cascade=CascadeType.ALL)
@JoinColumn(name="id_client")
private Client client;
@JsonIgnore
@ManyToMany(cascade=CascadeType.ALL)
@JoinTable(name="passager_reservation", [email protected](name="id_reservation"), [email protected](name="id_passager"))
private Collection<Passager> passagers;
@JsonIgnore
@ManyToMany(cascade=CascadeType.ALL)
@JoinTable(name="vol_reservation", [email protected](name="id_reservation"), [email protected](name="id_vol"))
private Collection<Vol> vols;
// Contructor without fields
public Reservation() {
super();
}
// contructor with date attribute
public Reservation(String date) {
super();
this.date = date;
}
// ----------------------- Getters and setters-------------------------------
public String getDate() {
return date;
}
public void setDate(String date) {
this.date = date;
}
public Client getClient() {
return client;
}
public void setClient(Client client) {
this.client = client;
}
public Collection<Passager> getPassagers() {
return passagers;
}
public void setPassagers(Collection<Passager> passagers) {
this.passagers = passagers;
}
public Collection<Vol> getVols() {
return vols;
}
public void setVols(Collection<Vol> vols) {
this.vols = vols;
}
}
und der Controller ist: // ------------------- eine Reservierung erstellen ----- -------------------------------------------------- -
@RequestMapping(value = "/ajouterReservation", method = RequestMethod.POST, consumes="application/json")
public ResponseEntity<String> ajouterReservation(@RequestBody Reservation reservation) {
metier.ajouterReservation(reservation);
return new ResponseEntity(HttpStatus.CREATED);
}
Ich testete auch den Anbieter mit Post-Mann und es funktioniert.
Der Fehler, den ich habe, sind unten bekommen:

versuchen verbrauchen Entfernen = „application/json“ in dem Provider oder stellen Sie den Header Content-Typ, bevor Sie den Rest Anruf – Barath
Ich habe bereits versucht, ohne konsumieren = „application/json“ und Header, aber ich erhalte die gleiche Störung – TarAll
Dann ist es Zeit, die Reservierungsinstanz zu analysieren, um die Antwort mit dem Eingabeanforderungskörper zu aktualisieren. Versuchen Sie auch, @RequestBody zu entfernen und überprüfen Sie, ob rest cal erfolgreich gemacht wurde, um das root casue zu identifizieren – Barath
