Java 初始化期间Hibernate PropertyNotFoundException-找不到MyEntity的setter#new

我目前正在迁移一个Hibernate实现，以使用

EntityManager

而不是

Session

。在初始化过程中，转储以下堆栈跟踪：

触发此异常的是什么

---

更新：以下是MyEntity的来源：

@Entity
@Table(name = "myEntity")
public class MyEntity extends BaseEntity {
    private String name;

    public MyEntity() {
    }

    public MyEntity(final String name) {
        this.name = name;
    }

    @Basic
    @NaturalId
    @Column(name = "name")
    public String getName() {
        return name;
    }

    public void setName(final String name) {
        this.name = name;
    }
}

@MappedSuperclass
public abstract class BaseEntity {
    protected UUID id;
    protected LocalDateTime created;
    protected LocalDateTime updated;

    @PrePersist
    public void prePersist() {
        preUpdate();
        created = updated;
    }

    @PreUpdate
    public void preUpdate() {
        updated = LocalDateTime.now();
    }

    @Id
    @GeneratedValue(strategy = GenerationType.SEQUENCE, generator = "uuid-generator")
    @GenericGenerator(name = "uuid-generator", strategy = "uuid2")
    @Column(name = "id")
    public UUID getId() {
        return id;
    }

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

    @Basic
    @Column(name = "created")
    public LocalDateTime getCreated() {
        return created;
    }

    public void setCreated(final LocalDateTime created) {
        this.created = created;
    }

    @Version
    @Column(name = "updated")
    public LocalDateTime getUpdated() {
        return updated;
    }

    public void setUpdated(final LocalDateTime updated) {
        this.updated = updated;
    }
}

和

BaseEntity

：

@Entity
@Table(name = "myEntity")
public class MyEntity extends BaseEntity {
    private String name;

    public MyEntity() {
    }

    public MyEntity(final String name) {
        this.name = name;
    }

    @Basic
    @NaturalId
    @Column(name = "name")
    public String getName() {
        return name;
    }

    public void setName(final String name) {
        this.name = name;
    }
}

@MappedSuperclass
public abstract class BaseEntity {
    protected UUID id;
    protected LocalDateTime created;
    protected LocalDateTime updated;

    @PrePersist
    public void prePersist() {
        preUpdate();
        created = updated;
    }

    @PreUpdate
    public void preUpdate() {
        updated = LocalDateTime.now();
    }

    @Id
    @GeneratedValue(strategy = GenerationType.SEQUENCE, generator = "uuid-generator")
    @GenericGenerator(name = "uuid-generator", strategy = "uuid2")
    @Column(name = "id")
    public UUID getId() {
        return id;
    }

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

    @Basic
    @Column(name = "created")
    public LocalDateTime getCreated() {
        return created;
    }

    public void setCreated(final LocalDateTime created) {
        this.created = created;
    }

    @Version
    @Column(name = "updated")
    public LocalDateTime getUpdated() {
        return updated;
    }

    public void setUpdated(final LocalDateTime updated) {
        this.updated = updated;
    }
}

显示实体

MyEntity

的java代码。请参阅编辑，不确定我最初为什么没有附加它！为什么在

MyEntity

类中有

SectorEntity

构造函数？因为我在复制到SO时没有更改它们，修复了！
