java.io.StreamCorruptedException: ungültiger Stream-Header: 41434544

Ich versuche LocalDateTime über Jackson zu seresize und zu deserialisieren. Ich benutze Winterschlaf + erholsame Webservices. Es ist meine Einheit:java.io.StreamCorruptedException: ungültiger Stream-Header: 41434544

@Entity 
@Table(name = "USERS") 
@NamedQueries(value = { 
    @NamedQuery(name = "getUser", query = "from User user where userId = ?") 
}) 
public class User extends ResourceSupport implements Serializable{ 

@Id 
@GeneratedValue(strategy = GenerationType.AUTO) 
@Column(name = "USER_ID") 
private long userId; 

@Column(name = "USER_NAME") 
private String userName; 

@Column(name = "USER_CREATED") 

@JsonSerialize(using = LocalDateTimeSerializer.class) 
@JsonDeserialize(using = LocalDateTimeDeserializer.class) 

private LocalDateTime userCreated; 

@Column(name = "USER_PHONE") 
private String userPhone; 


public User(){} 

@JsonCreator 
public User(@JsonProperty("userId") long userId, 
      @JsonProperty("userName") String userName, 
      @JsonProperty("phone") String phone) { 
    super(); 
    this.userId = userId; 
    this.userName = userName; 
    this.userPhone = phone; 
    this.userCreated = LocalDateTime.now(); 
} 
public long getUserId() { 
    return userId; 
} 
public void setUserId(long userId) { 
    this.userId = userId; 
} 
public String getUserName() { 
    return userName; 
} 
public void setUserName(String userName) { 
    this.userName = userName; 
} 

public LocalDateTime getUserCreated() { 
    return userCreated; 
} 

public void setUserCreated(LocalDateTime userCreated) { 
    this.userCreated = userCreated; 
} 

public String getUserPhone() { 
    return userPhone; 
} 

public void setUserPhone(String userPhone) { 
    this.userPhone = userPhone; 
} 

@Override 
public boolean equals(Object user){ 
    boolean result = false; 
    if((user==null)||!(user instanceof User)) 
     result = false; 
    else{ 
     User otherUser = (User)user; 
     result = this.getUserId() == otherUser.getUserId() && 
       this.getUserName() == otherUser.getUserName() && 
       this.getUserPhone() == otherUser.getUserPhone()&& 
       this.getUserCreated() == otherUser.getUserCreated(); 
    } 
    return result; 
} 

@Override 
public int hashCode(){ 
    return Long.hashCode(userId) ; 
}

Es ist mein Serializer ist:

public class LocalDateTimeSerializer extends JsonSerializer<LocalDateTime>{ 

    @Override 
    public void serialize(LocalDateTime arg0, JsonGenerator arg1, SerializerProvider arg2) 
      throws IOException, JsonProcessingException { 
     // TODO Auto-generated method stub 
     DateTimeFormatter formatter = DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss"); 
     String formattedDateTime = arg0.format(formatter); 
     arg1.writeString(formattedDateTime); 
    } 

}

Es ist mein Deserializer:

public class LocalDateTimeDeserializer extends JsonDeserializer<LocalDateTime> { 

    @Override 
    public LocalDateTime deserialize(JsonParser arg0, DeserializationContext arg1) 
      throws IOException, JsonProcessingException { 
     // TODO Auto-generated method stub 
     DateTimeFormatter formatter = DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss"); 
     LocalDateTime localDateTime = LocalDateTime.parse(arg0.getText(), formatter); 
     return localDateTime; 
    } 

}

Es ist meine DAO Klasse:

@Repository 
public class UserDAOImpl implements UserDAO{ 

@Autowired 
private SessionFactory sessionFactory; 

public UserDAOImpl(){} 
public UserDAOImpl(SessionFactory sessionFactory){ 
    this.sessionFactory = sessionFactory; 
} 


@Override 
public User getUser(long userId) { 
    //Session session = sessionFactory.getCurrentSession(); 
    Session session = sessionFactory.openSession(); 
    Query query = session.getNamedQuery("getUser"); 
    query.setParameter(0, userId); 

    return (User)query.uniqueResult();// this string invokes error 
} 
@Override 
public void addUser(User user) { 
    // TODO Auto-generated method stub 
    Session session = sessionFactory.openSession(); 
    user.setUserCreated(LocalDateTime.now()); 
    session.save(user); 
    session.flush(); 
    session.close(); 
}

Es ist der Wert von USER_CREA TED Feld meiner gespeicherten Benutzer:

ACED00057372000D6A6176612E74696D652E536572955D84BA1B2248B20C00007870770E05000007E004110F261012C684C078

Wenn ich Benutzer in den db, das Hinzufügen Operation erfolgreich ausgeführt wird, aber wenn ich versuchen, Benutzer von DB bekomme ich Fehler:

41434544 dekodiert als die Zeichen "ACED". Läutet das irgendwelche Glocken? –

Welche Zeile Ihres Codes löst diese Ausnahme aus? – EJP

Da ist etwas Eigenartiges. Der Stacktrace dient zur Java-Objektserialisierung, der Code in der Frage dient jedoch zur JSON-Serialisierung. –

Hibernate nicht unterstützt LocalDateTime, es sei denn, Sie fügen Ihrem Klassenpfad an additional jar hinzu.

Das bedeutet, dass ohne LocalDateTime jede serialisierbare Klasse behandelt wird und die native Java-Serialisierung verwendet wird, um den Wert in einer binären Spalte der Tabelle zu speichern. Das willst du wirklich, wirklich nicht.

Vergleichen Sie auch keine Objekte mit ==. Und beachte, dass dies nichts mit JSON und Jackson zu tun hat.

* "Und beachten Sie, dass dies nichts mit JSON und Jackson zu tun hat." Das bedeutet, dass der gesamte Code, den das OP in der ersten Version des Q gepostet hat, irrelevant ist. –

Vielen Dank. Ich habe dieses Jar hinzugefügt und Converter für LocalDateTime und Timestamp-Typen erstellt. Alles funktioniert – Yuriy

Ich denke ich verstehe, was hier vorgeht. Hier sind die Hinweise.

Die Zahl 41.434.544 (hexadezimal) dekodiert, wie die Buchstaben "A", "C", "E", "D".
Eine Java-Objekt-Serialisierung beginnt mit einer 16-Bit-Magic-Nummer, deren Wert in Hexadezimal ACED ist. (Referenz: https://docs.oracle.com/javase/6/docs/platform/serialization/spec/protocol.html)

So sieht es aus wie Sie Folgendes getan haben:

Sie einen Gegenstand in ein Byte-Array serialisiert haben.
Sie haben das Byte-Array in einen Text umgewandelt, der eine hexadezimale Darstellung der Bytes enthält.
Sie haben diesen Text in einer VARCHAR (oder einer ähnlichen) Spalte einer Tabelle gespeichert.
Sie haben dann den Text abgerufen.
Sie haben String.getBytes (...) verwendet, um den Text in Bytes zu konvertieren.
Sie haben versucht, die Bytes zu deserialisieren.

Das Problem ist, dass Schritt 5 falsch ist. Sie müssen den Text in Bytes konvertieren, indem Sie die Zeichenfolge in Zeichenpaare (Hexadezimalziffern) aufteilen und jedes Paar in ein Byte konvertieren.

UPDATE - offenbar wird Hibernate die Serialisierung hinter den Kulissen zu tun, und die richtige Lösung ist, um es zu stoppen geschieht; siehe @JB Nizets Antwort.
