Springboot uses DataRest to directly access the database

Spring-boot-data-rest

Directly map database resources to Rest resources

illustrate

• Spring Data REST is based on Spring Data's repository, which can automatically output the repository as a REST resource.
• Currently, repositories that support Spring Data JPA, Spring Data MongoDB, Spring Data Neo4j, Spring Data GemFire, and Spring Data Cassandra are automatically converted to REST services. Note that it is automatic.
• To put it simply, Spring Data REST automates the large number of REST template interfaces we need to write
• Generally used to directly expose the content of the database to the front end
