关于实体继承解决方式

参考：https://github.com/spring-projects/spring-data-book/blob/master/jpa/src/main/java/com/oreilly/springdata/jpa/core/AbstractEntity.java

@MappedSuperclass
public class AbstractEntity{
  //子类都需要的字段可写在这里
   @Column(length = 6)
   private String name;
   ... ...
}


@Entity
@Table(name = "child")
public class ChildEntity extends AbstractEntity{
... ...
}
