First, we'll set the store type in our application.properties: spring.quartz.job-store-type=jdbc. The template programming model is equivalent to other Spring templates and builds the basis for interaction with the graph and is also used for the Spring Data repository support. Once an instance of the entity has been created, Spring Data populates all remaining persistent properties of that class. Created an Entity Bean class (Student) with an auto-incrementing primary key. Let me explain it briefly. Added a Spring Data Repository interface (StudentRepository). Setting up a JDBC JobStore in Spring takes a few steps. Similar to Spring Data JPA, Spring Data JDBC uses, by default, a naming strategy that maps Java entities to relational database tables, and attributes to column names. In the current implementation, entities referenced from an aggregate root JPA and Spring Data JPA 31.3.1.
