This article focuses on "how to achieve spring persistence". Interested friends may wish to have a look at it. The method introduced in this paper is simple, fast and practical. Now let the editor to take you to learn "the implementation of spring persistence" bar!

Rely on spring-data-jpa

Spring-data-jpa feature: 1:Repository: the top-level interface, which is an empty interface, is designed to unify all Repository types and allow components to automatically identify when scanning. 2:CrudRepository: is a sub-interface of Repository, providing the functions of CRUD. 3:PagingAndSortingRepository: is a sub-interface of CrudRepository, adding paging and sorting functions 4:JpaRepository: is a sub-interface of PagingAndSortingRepository, adding some practical functions, such as batch operation, etc. 5:JpaSpecificationExecutor: interface used for query 6:Specification: is a query specification provided by Spring Data JPA. To make complex queries, you only need to set query conditions around this specification.

All dao in the repository package needs to inherit JpaRepository and JpaSpecificationExecutor, without the @ Repository annotation, and can access and manipulate data with almost no writing implementation.

At this point, I believe you have a deeper understanding of "the implementation of spring persistence". You might as well do it in practice. Here is the website, more related content can enter the relevant channels to inquire, follow us, continue to learn!
