英文:
Complex Object as Inner Class inside Hibernate Entity
问题
现在，我知道内部类不能作为Hibernate中的实体。
我首先会展示我的代码，请参考我下面的问题：
@Entity@Table(name = "bags")public class Bags extends AbstractModel {private String brand;private String condition;private String size;private Extras extras;@ManyToOneprivate Customer customer;private class Extras {private boolean box;private boolean authenticity_card;private boolean shoulder_strap;private boolean dustbag;private boolean pouch;private boolean padlock_and_key;private boolean bagcharm;private boolean nameTag;private boolean mirror;}}
已省略Getter和Setter。我的问题是：
如果我想要一个稍微复杂一些的对象，比如Extras，在其中表示多个配饰的存在与否，是创建与bags相关联的附加表会更好，还是有其他方法可以解决这个问题？
如果我表达不清楚或者您需要额外的信息，请告诉我。
英文:
Now, I'm aware that an Inner class cannot be an Entity in Hibernate.
I'll first show my code, please refer to my question below:
@Entity@Table(name = "bags")public class Bags extends AbstractModel {private String brand;private String condition;private String size;private Extras extras;@ManyToOneprivate Customer customer;private class Extras {private boolean box;private boolean authenticity_card;private boolean shoulder_strap;private boolean dustbag;private boolean pouch;private boolean padlock_and_key;private boolean bagcharm;private boolean nameTag;private boolean mirror;}}
Getters and setters are ommited. My question is:
If I want to have a slightly more complex object such as Extras, in which I represent the absence or not of several accessories, would it be better to create an additional table associated with bags OR is there a way around this?
Please let me know if I was not clear or you require additional information.

@Embeddable注解用于声明一个类将被其他实体嵌入。
@Embeddablepublic class Extras {private boolean box;private boolean authenticity_card;private boolean shoulder_strap;private boolean dustbag;private boolean pouch;private boolean padlock_and_key;private boolean bagcharm;private boolean nameTag;private boolean mirror;}
@Embedded用于将一个类型嵌入另一个实体中。
@Entity@Table(name = "bags")public class Bags extends AbstractModel {private String brand;private String condition;private String size;private Extras extras;@ManyToOneprivate Customer customer;@Embeddedprivate Extras extras;}
英文:
@Embeddable annotation is used to declare a class will be embedded by other entities.
@Embeddablepublic class Extras {private boolean box;private boolean authenticity_card;private boolean shoulder_strap;private boolean dustbag;private boolean pouch;private boolean padlock_and_key;private boolean bagcharm;private boolean nameTag;private boolean mirror;}
@Embedded is used to embed a type into another entity.
@Entity@Table(name = "bags")public class Bags extends AbstractModel {private String brand;private String condition;private String size;private Extras extras;@ManyToOneprivate Customer customer;@Embeddedprivate Extras extras;}
