我有問題,當在JPA更新對象無法得到通過反射的字段值冬眠
我有豆用戶
public class User {
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
@Column(name = "id", unique = true, nullable = false)
private Long id;
@Column(name = "name", nullable = false)
private String name;
@OneToMany(fetch = FetchType.EAGER)
@JoinColumn(name = "fk_program_rating")
private List<Rating> ratingList = new ArrayList<Rating>();
}
和
public class Rating extends BaseModel {
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
@Column(name = "id", unique = true, nullable = false)
private Long id;
@ManyToOne()
@JoinColumn(name = "fk_program_rating", nullable = false)
@ForeignKey(name = "FK_prog_rate")
@OnDelete(action = OnDeleteAction.CASCADE)
private Program program;
}
時,試圖更新給我例外情況:無法通過反映 得到的字段值發生在表格評級有行時
ERROR TransactionInterceptor:434 - 應用程序異常被提交異常覆蓋 com.vodafone.visradio.dataaccess.exception.DataAccessException:org.hibernate.PropertyAccessException:無法通過com.vodafone.visradio的反射getter獲取字段值。 dataaccess.model.Rating.id
有關此問題的任何幫助
感謝
您是如何嘗試通過反射訪問它的? – m3th0dman
@ m3th0dman:我沒有通過反射訪問任何東西 – abdelhady
那麼你的評級類有一個getter方法你的'ID'屬性? – Matthias
