Java Hibernate ConstraintViolationException:在删除时无操作在更新时无操作

我正在使用Java、Spring、Hibernate和JPA

MapRange.java

@Entity
@Table(name = "map_range")
@XmlRootElement(name = "map_range")
public class MapRange extends AbstractDomain<Long> {

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

    @Size(min = 1, max = 100)
    @Column(name = "NAME", nullable = false)
    private String name;

    @Column(name = "RADIUS", nullable = false)
    private Integer radius;

    @OneToMany(cascade = CascadeType.ALL, fetch = FetchType.EAGER, orphanRemoval = true)
    @JoinTable(name = "map_location", joinColumns = {
            @JoinColumn(name = "MAP_ID", referencedColumnName = "ID") }, inverseJoinColumns = {
                    @JoinColumn(name = "LOC_ID", referencedColumnName = "ID", unique = true) })
    private Set<LocationMap> locations;

@Entity
@Table(name = "location_map")
@XmlRootElement(name = "location_map")
public class LocationMap extends AbstractDomain<Integer> {

    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    @Basic(optional = false)
    @Column(name = "ID", unique = true, nullable = false)
    private Integer id;

    @Column(name = "LATITUDE", nullable = false)
    private BigDecimal latitude;

    @Column(name = "LONGITUDE", nullable = false)
    private BigDecimal longitude;

我得到以下错误：

如果有人能就我如何解决此问题提供一些建议，我将非常感谢您的帮助。

您如何创建实体的实例？您只需向我们显示您正在调用

merge

操作，但不显示它们是如何创建和映射的。@Richard您使用的

BeanUtils

是什么？

super.merge(mapRange);

    BeanUtils.copyProperties(entity, attached);
    entityManager.setFlushMode(FlushModeType.COMMIT);
    attached = entityManager.merge(attached);
