无法使用 Spring 更新实体

问题描述 投票：0回答：1

我在 springboot 的这个异常中遇到了一些麻烦： Association 实例的标识符从 Association@42c3ddac 更改为 Association@5f8c91f9。

我真的不明白为什么会出现此异常，因为我只是在使用此方法更改非键属性时保存对象：

@PutMapping("/accept")
    public ResponseEntity<SoumissionDto> setAssociationToAccepted(@RequestBody AssociationDto associationDto) {
        try {
            Canvas canvas = canvasService.getCanvasByCodeInvitation(associationDto.getCodeInvitation());
            Canvas canvasSoumis = canvasService.getCanvasById(associationDto.getGuidcanvasIndividuel());
            Association updatedAssociation = associationService.getAssociationByCanvasCollabAndCanvas(canvas.getGUIDCanvas(), canvasSoumis.getGUIDCanvas());
            if (updatedAssociation == null) {
                return new ResponseEntity<>(HttpStatus.NOT_FOUND);
            } else {
                System.out.println("j'ai eu cette asso id :  "+ updatedAssociation.getCanvas().getGUIDCanvas().toString() +"  id collab  " + updatedAssociation.getCanvasEquipe().getGUIDCanvas().toString());
                updatedAssociation.setStatut(true);
                
Association returnAssociation = associationService.updateAssociation(updatedAssociation);
                SoumissionDto soumissionDto = createSoumissionDtoFromAssociation(returnAssociation);
                return new ResponseEntity<>(soumissionDto, HttpStatus.OK);
            }
        } catch (Exception e) {
            System.out.println("J'ai une erreur : "+e.getMessage());
            System.out.println("stack : "+ Arrays.toString(e.getStackTrace()));
            System.out.println("cause : "+e.getCause());

            return new ResponseEntity<>(HttpStatus.INTERNAL_SERVER_ERROR);
        }
    }

这里是 POJO 协会：

@Entity
@Table(name = "Association")
@IdClass(Association.class)
public class Association {

    @Id
    @ManyToOne
    @JoinColumn(name = "canvas_collectif", nullable = false)
    @OnDelete(action = OnDeleteAction.CASCADE)
    @JsonBackReference
    private Canvas canvas_collectif;

    @Id
    @ManyToOne
    @JoinColumn(name = "canvas", nullable = false)
    @OnDelete(action = OnDeleteAction.CASCADE)
    @JsonBackReference
    private Canvas canvas;


    @Column(name = "statut", nullable = false, length = 200)
    private boolean statut;
//with the usual getter and setter
}

在我的数据库中，关联使用由canvas id和canvas_collaboratifId组成的键，并具有布尔属性名称statut。

通过这种方法，我的目标是将statut属性更改为true

我不明白为什么我无法保存我的关联，因为我什至没有触及 ids...

感谢您的宝贵时间 祝大家有美好的一天

好的，我找到了解决方案， 由于我使用的是复合键，因此我需要创建一个实现 Serialized 的类 Association_PK 并在 Association 中声明它。 以下是课程：

package com.cogiteo.canvas.entities;

import java.io.Serializable;

public class Association_PK implements Serializable {
    private long canvas_collectif;
    private long canvas;

    public Association_PK() {
    }

    public Association_PK(long canvas_collectif, long canvas) {
        this.canvas_collectif = canvas_collectif;
        this.canvas = canvas;
    }
}

以及更新后的协会：

package com.cogiteo.canvas.entities;

import org.hibernate.annotations.OnDelete;
import org.hibernate.annotations.OnDeleteAction;

import com.fasterxml.jackson.annotation.JsonBackReference;

import jakarta.persistence.Column;
import jakarta.persistence.Entity;
import jakarta.persistence.Id;
import jakarta.persistence.IdClass;
import jakarta.persistence.JoinColumn;
import jakarta.persistence.ManyToOne;
import jakarta.persistence.Table;


@Entity
@Table(name = "Association")
@IdClass(Association_PK.class)
public class Association {

    @Id
    @ManyToOne
    @JoinColumn(name = "canvas_collectif", nullable = false)
    @OnDelete(action = OnDeleteAction.CASCADE)
    @JsonBackReference
    private Canvas canvas_collectif;

    @Id
    @ManyToOne
    @JoinColumn(name = "canvas", nullable = false)
    @OnDelete(action = OnDeleteAction.CASCADE)
    @JsonBackReference
    private Canvas canvas;


    @Column(name = "statut", nullable = false, length = 200)
    private boolean statut;


    public Canvas getCanvas() {
        return canvas;
    }

    public void setCanvas(Canvas canvas) {
        this.canvas = canvas;
    }

    public boolean getStatut() {
        return statut;
    }

    public void setStatut(boolean statut) {
        this.statut = statut;
    }

    public Canvas getCanvasEquipe() {
        return canvas_collectif;
    }

    public void setCanvasEquipe(Canvas canvas) {
        this.canvas_collectif = canvas;
    }
}

感谢大家的宝贵时间！ 祝你有美好的一天！
