Hibernate/Spring/Jpa @oneToMany Kaskade Update

Question

Ich versuche, in den Dekorator Cascade = CascadeType.ALL auf dem Feld eins zu viele meiner Version Modell im Frühjahr hinzufügen, um jeden Hyper-Parameter zu aktualisieren, wenn ich meine aktualisieren Version. Wie Sie unten sehen können.

@Entity 
    @Table(name = "version") 
    @Cache(usage = CacheConcurrencyStrategy.NONSTRICT_READ_WRITE) 
    public class Version implements Serializable { 

     private static final long serialVersionUID = 1L; 

     @Id 
     @GeneratedValue(strategy = GenerationType.IDENTITY) 
     private Long id; 

     @NotNull 
     @Column(name = "num", nullable = false) 
     private Integer num; 

     @Column(name = "creation_date") 
     private ZonedDateTime creationDate;

     private String weightsURI; 

     @OneToMany(mappedBy = "version", fetch = FetchType.EAGER, orphanRemoval = true) 
     @JsonIgnoreProperties({"version", "metricsType"}) 
     @Cache(usage = CacheConcurrencyStrategy.NONSTRICT_READ_WRITE) 
     private Set<ResultExecution> resultExecutions = new HashSet<>(); 

     @OneToMany(mappedBy = "version", fetch = FetchType.EAGER, orphanRemoval = true, cascade = CascadeType.ALL) 
     @JsonIgnoreProperties({"version"})

     public Set<ResultExecution> getResultExecutions() {

     public Version resultExecutions(Set<ResultExecution> resultExecutions) {

      return this; 
     } 

     public Version addResultExecution(ResultExecution resultExecution) { 
      this.resultExecutions.add(resultExecution); 
      resultExecution.setVersion(this); 
      return this; 
     } 

     public Version removeResultExecution(ResultExecution resultExecution) {

     public void setResultExecutions(Set<ResultExecution> resultExecutions) {

     public Version addHyperParameter(HyperParameter hyperParameter) {

      return this; 
     } 

     public void setModelConfiguration(ModelConfiguration modelConfiguration) { 
      this.modelConfiguration = modelConfiguration; 
     } 
     // jhipster-needle-entity-add-getters-setters - Jhipster will add getters and setters here, do not remove 

     @Override 
     public boolean equals(Object o) { 
      if (this == o) {

      if (o == null || getClass() != o.getClass()) {

      Version version = (Version) o;

     @Override

     @Override

    } 

Mein Hyper Modell sieht wie folgt aus:

@Entity 
@Table(name = "hyper_parameter") 
@Cache(usage = CacheConcurrencyStrategy.NONSTRICT_READ_WRITE) 
public class HyperParameter implements Serializable { 

    private static final long serialVersionUID = 1L; 

    @Id 
    @GeneratedValue(strategy = GenerationType.IDENTITY) 
    private Long id; 

    @NotNull 
    @Column(name = "parameter_value", nullable = false) 
    private String parameterValue; 

    @ManyToOne(optional = false) 
    @NotNull 
    @JsonIgnoreProperties({"resultExecutions", "hyperParameters", "data", "modelConfiguration"}) 
    private Version version; 
public Long getId() { 
    return id; 
} 

public void setId(Long id) { 
    this.id = id; 
} 

public String getParameterValue() { 
    return parameterValue; 
} 

public HyperParameter parameterValue(String parameterValue) { 
    this.parameterValue = parameterValue; 
    return this; 
} 

public void setParameterValue(String parameterValue) { 
    this.parameterValue = parameterValue; 
} 

public Version getVersion() { 
    return version; 
} 

public HyperParameter version(Version version) { 
    this.version = version; 
    return this; 
} 

public void setVersion(Version version) { 
    this.version = version; 
} 

public HyperParameterType getHyperParameterType() { 
    return hyperParameterType; 
} 

public HyperParameter hyperParameterType(HyperParameterType hyperParameterType) { 
    this.hyperParameterType = hyperParameterType; 
    return this; 
} 

public void setHyperParameterType(HyperParameterType hyperParameterType) { 
    this.hyperParameterType = hyperParameterType; 
} 
// jhipster-needle-entity-add-getters-setters - Jhipster will add getters and setters here, do not remove 

@Override 
public boolean equals(Object o) { 
    if (this == o) { 
     return true; 
    } 
    if (o == null || getClass() != o.getClass()) { 
     return false; 
    } 
    HyperParameter hyperParameter = (HyperParameter) o; 
    if (hyperParameter.getId() == null || getId() == null) { 
     return false; 
    } 
    return Objects.equals(getId(), hyperParameter.getId()); 
} 

@Override 
public int hashCode() { 
    return Objects.hashCode(getId()); 
} 

@Override 
public String toString() { 
    return "HyperParameter{" + 
     "id=" + getId() + 
     ", parameterValue='" + getParameterValue() + "'" + 
     "}"; 
} 

}

ich eine json aktualisieren und einen Put mit ihm versuchen .I den Wert des Feldes parameter von 2 bis ändern 3 .

{ 
    "id": 1, 
    "num": 1, 
    "creationDate": "2017-05-11T00:00:00+02:00", 
    "executionDate": null, 
    "weightsURI": "tests/scripts/sequential/weights/weights_le_net_5.h5py", 
    "resultExecutions": [ 
     { 
     "id": 1, 
     "metricValues": "", 
     "executionType": "TRAIN", 
     "numPrediction": null 
     }, 
     { 
     "id": 2, 
     "metricValues": "", 
     "executionType": "TRAIN", 
     "numPrediction": null 
     } 
    ], 
    "hyperParameters": [ 
     { 
     "id": 1, 
     "parameterValue": "2", 
     "hyperParameterType": {

      "name": "epochs", 
      "parameterType": "INTEGER", 
      "parameterDefaultValue": "0", 
      "isRequired": true 
     } 
     }, 
     { 
     "id": 2, 
     "parameterValue": "32", 
     "hyperParameterType": { 
      "id": 2, 
      "name": "batch_size", 
      "parameterType": "INTEGER", 
      "parameterDefaultValue": "32", 
      "isRequired": true 
     } 
     } 
    ], 
    "modelConfiguration": { 
     "id": 1, 
     "name": "Modele LeNet5", 
     "creationDate": "2017-05-11T00:00:00+02:00",

     "saveURI": "tests/scripts/sequential/models/le_net_5.json" 
    } 
    } 

Aber wenn ich das tue ich habe einen 500 interne serveur Fehler und Stack-Trace wie der Balg über eine Null-Einschränkungsverletzung.

<!-- What do you expect the result to be? --> 

<!-- What is the actual result you get? (Please include any errors.) -->

] 

Wie kann ich meine hyperParameters aktualisieren, wenn ich meine Version aktualisiere, ohne diesen Fehler zu bekommen.

Answer 1

Verwenden Sie die @PreUpdate und @PrePersist Rückrufe in der Hyper Klasse wie folgt:

@PreUpdate 
@PrePersist 
public void setChildObjects() { 
    if (getVersions() != null) 
    { 
     for (Version version : getVersions()) 
     { 
      version.setHyperParameters (this); 
     } 
    } 
} 

für weitere Informationen hierzu siehe: http://docs.jboss.org/hibernate/core/3.3/reference/en/html/tutorial.html#tutorial-associations-usingbidir

Answer 2

Sie haben soeben Validierungsfehler haben. Sie versuchen interpolatedMessage mit Nullwert zu setzen. Ok, aber zuerst @NotNull Annotation in diesem Feld entfernen.

Answer 3

Beide Lösung tatsächlich funktionieren, ich hatte einen zweiten Fehler wegen dem, was in diesem Thema diskutiert wird: Spring data rest one to many cascade all. Ich musste @ JsonManagedReference und @JsonBackReference nur hinzufügen, weil ich Marshalling-Problem auf der Referenz der Version hatte, wenn ich versuchte, meine HyperParameters in Kaskade zu aktualisieren.
