如何使一个可嵌入类的ids唯一地组合在一起spring data jpa，这样就不会输入重复的内容

@Embeddable
public class EmbeddableId implements Serializable {
    private Long id1;
    private Long id2;

    // 构造函数、getter和setter方法
}

@Entity
public class YourEntity {
    @EmbeddedId
    @AttributeOverrides({
        @AttributeOverride(name = "id1", column = @Column(name = "id1")),
        @AttributeOverride(name = "id2", column = @Column(name = "id2"))
    })
    private EmbeddableId id;

    // 其他属性和方法
}

@Embeddable
public class EmbeddableId implements Serializable {
    // 省略其他代码

    @Override
    public boolean equals(Object o) {
        if (this == o) return true;
        if (o == null || getClass() != o.getClass()) return false;
        EmbeddableId that = (EmbeddableId) o;
        return Objects.equals(id1, that.id1) && Objects.equals(id2, that.id2);
    }

    @Override
    public int hashCode() {
        return Objects.hash(id1, id2);
    }
}
