RestTempleteとpostForObjectを使用した400の不正リクエスト

Question

私はSpring 3を使用して2つのアプリケーションを構築しています。最初のAPIは残りAPIであり、2番目はクライアントです。クライアントは予約を作成する必要があります。 400リクエストが間違っています。ご協力ください。

クライアントアプリでクラス予約：

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", joinColumns=@JoinColumn(name="id_reservation"), inverseJoinColumns=@JoinColumn(name="id_passager")) 
    private Collection<Passager> passagers; 
    @JsonIgnore 
    @ManyToMany(cascade=CascadeType.ALL) 
    @JoinTable(name="vol_reservation", joinColumns=@JoinColumn(name="id_reservation"), inverseJoinColumns=@JoinColumn(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; 
    } 

} 

残りクライアント：

// ----------------- - 予約を作成する--------------------------------------------- -----------

そして、クラスReservaプロバイダアプリでション：

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", joinColumns=@JoinColumn(name="id_reservation"), inverseJoinColumns=@JoinColumn(name="id_passager")) 
    private Collection<Passager> passagers; 
    @JsonIgnore 
    @ManyToMany(cascade=CascadeType.ALL) 
    @JoinTable(name="vol_reservation", joinColumns=@JoinColumn(name="id_reservation"), inverseJoinColumns=@JoinColumn(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; 
    } 


} 

とコントローラがある： // -------------------予約を作成します。----- -------------------------------------------------- -

@RequestMapping(value = "/ajouterReservation", method = RequestMethod.POST, consumes="application/json") 
    public ResponseEntity<String> ajouterReservation(@RequestBody Reservation reservation) { 
     metier.ajouterReservation(reservation); 
     return new ResponseEntity(HttpStatus.CREATED); 
    } 

私は郵便配達員を使用してプロバイダをテストしています。

私は取得していますエラーは以下の通りです：

Answer 1

根本原因：問題は、プロバイダのコントローラに設定されたコンテンツタイプである：

@RequestMapping(value = "/ajouterReservation", method = RequestMethod.POST, consumes="application/json") 
    public ResponseEntity<String> ajouterReservation(@RequestBody Reservation reservation) 

解決方法1：ハンドラメソッドでconsumes="application/json"を削除

解決策2：残りのコールを行う前にヘッダを設定し、RestTemplateの交換メソッドを以下のように使用します。

 RestTemplate restTemplate = new RestTemplate(); 
    HttpHeaders headers=new HttpHeaders(); 
     headers.set("Content-Type", "application/json"); 
    HttpEntity requestEntity=new HttpEntity(reservation, headers); 

     Reservation addedRes = restTemplate.exchange(REST_SERVICE_URI, HttpMethod.POST,requestEntity,Reservation.class);
