Java- JPA @Entity和@Embeddable在一起

Question

我是Spring jpa的新手，有一个需要创建的用例：

表A：带有列'a'，'b'和'c'

和表B：具有列d和表A中的列。

我的问题是，

我可以用@ Entity和@ Embeddable都为Table A注释POJO吗？

Answer 1

You will have to put two annotation by name "@Embeddable And
@MappedSuperclass" on above the table A entity and also you will have to inherit table A entity into the table B entity like below.

@Embeddable
@MappedSuperclass
@Entity
class TableA{....}

@Entity
Class TableB extends TableA{...}
