如何在 Java/Spring/Hibernate 中从数据库中删除实体并将克隆存储在不同的数据库表中

Question

My goal is

1. Delete entity in current table
2. Clone the deleted entity to another table to store for future reference

Thanks

My suggestion is to not delete first, but rather copy the entity into the table you wish, make sure it is successfull by checking the result code, then delete the entity from the table.

INSERT INTO copy_table 
SELECT * FROM original_table
WHERE condition; 

DELETE FROM original_table
WHERE condition;

In JPA

https://docs.spring.io/spring-data/jpa/docs/1.5.0.RELEASE/reference/html/jpa.repositories.html

Entity x = jpaRepository.findById(id);

cloneTableJpaRepo.save(x);

jpaRepository.delete(x);
