RepositoryRestResource annotation in Spring Boot 2 not accessible - spring-boot

Question

I can not seem to get the #RepositoryRestResource to work on my simple lesson. Here is where my code is on GitHub:
https://github.com/txt8888/SB2-RepositoryRestResource
Basically,
A department entity: (I know the database connection works)
#Data
#AllArgsConstructor
#NoArgsConstructor
#Entity
#Table(name = "departments")
public class Department {
#Id
private String id;
private String name;
}
and the Repository:
#CrossOrigin
#RepositoryRestResource(collectionResourceRel = "departments",
path = "departments")
public interface DepartmentRepository extends JpaRepository<Department, String> {
}
and my pom.xml
<?xml version="1.0" encoding="UTF-8"?>

when I hit the http://localhost:8080/departments, it returns 404 not found.
http://localhost:8080/actuator/mappings does not show the endpoint either.
Did I miss something obvious?

Answer 1

I found out what was the issue. I forgot to include this dependencies:
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-rest</artifactId>
</dependency>
I previously had this dependency instead:
<dependency>
<groupId>org.springframework.data</groupId>
<artifactId>spring-data-rest-core</artifactId>
<version>2.6.10.RELEASE</version>
</dependency>
