无法用JPA更新实体，因为@onetoone依赖属性是不可变的，但没有@immutable注释 &g

Question

我要更新行:

 @PutMapping(value = "/updateEdits")
    @Transactional
    public void updateGeometry(@RequestBody List<Geometry> values){
        geometryRepository.saveAll(values);
    }

但它不工作。

WARN 12400—[nio-8080- exc -8] . h.p.p entity. abstractentitypersister: HHH000502: [com.sam .fiberplanner.entity.]的[feature]属性。[几何]实体被修改了，但它不会被更新，因为属性是不可变的。

相关实体:

@Getter
@Setter
@ToString
@RequiredArgsConstructor
@Entity
public class Geometry {
    @Id
    private Long gId;
    private String type;
    @Column(columnDefinition = "TEXT")
    private String coordinates;
    @OneToOne
    @MapsId
    private Feature feature;
}
@Getter
@Setter
@ToString
@RequiredArgsConstructor
@Entity
public class Feature {
    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private long fId;
    private String type;
    @ToString.Exclude
    @OneToOne(mappedBy = "feature",cascade = CascadeType.ALL)
    private Properties properties;
    @ToString.Exclude
    @OneToOne(mappedBy = "feature",cascade = CascadeType.ALL)
    private Geometry geometry;
    @ToString.Exclude
    @ManyToOne
    @JoinColumn(name = "geo_json_id")
    private GeoJson geoJson;
}

为什么[feature]属性是不可变的?我如何更新表?

Answer 1

如果可以的话试试

@Entity(mutable = "true")

Answer 2

在此关系中将cascade=CascadeType.ALL添加到您的实体关系

@OneToOne
@MapsId
private Feature feature;

，它将使实体可变
