Spring Boot - 实体中的自定义类字段答案

【问题标题】：Spring Boot - custom class field in entitySpring Boot - 实体中的自定义类字段

【问题描述】：

我有 2 个自定义类，OzBakim 和 GunlukEtkinlik。这些类不是实体。我需要在实体中使用这些类。

但我得到一个错误：

在类中定义名称为“entityManagerFactory”的 bean 创建错误路径资源

我该如何解决这个问题？

到目前为止我得到了什么：

@Entity
@Table
@EntityListeners(AuditingEntityListener.class)
public class Rapor implements Serializable {

    @Id
    @SequenceGenerator(name = "RAPOR_SEQUENCE", sequenceName = "RAPOR_SEQUENCE", allocationSize = 1)
    @GeneratedValue(strategy = GenerationType.SEQUENCE, generator = "RAPOR_SEQUENCE")
    private Long id;

    @Embedded
    private OzBakim ozBakim;

    @Embedded
    private GunlukEtkinlik gunlukEtkinlik;

    private Date tarih;

//Set Get
}

更新

@Embeddable
public class GunlukEtkinlik {
    private boolean anaDil;
    private boolean bahce;
    private boolean bilimDeney;
    private boolean drama;
    private boolean dans;
    private boolean fenDoga;
    private boolean gezi;
    private boolean gorselSanatlar;
    private boolean masaBasiEtkinlik;
    private boolean masal;
    private boolean matematik;
    private boolean mutfakEtkinlik;
    private boolean muzik;
    private boolean oyun;
    private boolean satranc;
    private boolean spor;
    private boolean ingilizce;
    private boolean digerDiller;
    private boolean yaraticiEtkinlik;
    private boolean ogretmenNotu;
//Set Get
}

@Embeddable
public class OzBakim {
    private int kahvalti;
    private int ogleYemegi;
    private int ikindiKahvaltisi;
    private int elYuzTuvaletTemizligi;
    private int okulFaaliyetleri;
    private int arkadasIletisim;
    private int ogleUykusu;
    private int ogretmenNotu;
    private int topluOgretmenNotu;
//Set Get
}

错误：

【问题讨论】：

并且那个异常会有一个嵌套的异常告诉你真正的原因。
请写完整的堆栈跟踪。

@NeilStockton 我更新了。
堆栈跟踪？ “e.printStackTrace”的输出 ...

【解决方案1】：

我发现了错误。 :)

Repeated column in mapping for entity: com.exam.model.Rapor column: ogretmen_notu (should be mapped with insert="false" update="false")

@Entity 类中的@Embeddable 实体，这使得它可以在@Entity 类的同一个表中添加嵌入实体的列。

不能使用重复的列名。

@Embeddable
public class GunlukEtkinlik {
    .
    .
    .
    private boolean ogretmenNotu;
}

和

@Embeddable
public class OzBakim {
    .
    .
    .
    private int ogretmenNotu(You must change name);
}
