Creating a Repository Interface
We'll cover the following
Defining an interface
Spring’s CrudRepository
interface provides all the methods like findById()
and save()
to fetch from the database or to update the database. All we need to do is define a specialized interface to extend the CrudRepository
. Spring Data will generate implementations for interfaces that extend CrudRepository
.
Kotlin vs. Java
If we were writing in Java, we’d write something like:
//Java code only for comparison purpose
package com.agiledeveloper.todo;
import org.springframework.data.repository.CrudRepository;
interface TaskRepository extends CrudRepository<Task, Long> {
}
