couldn't resolve the issue "Consider defining a bean named 'mongoTemplate' in your configuration." in spring data

I am building a simple spring boot application to save some data into Mongo. I am stuck with the issue "Consider defining a bean named 'mongoTemplate' in your configuration.". I tried many things. But nothing works. Below is the code.

Student Bean

private UUID id;

private int rollNumber;

private String name;

public Student(UUID id, int rollNumber, String name) {
    this.id = id;
    this.rollNumber = rollNumber;

Repository

 public interface StudentsRepository extends MongoRepository<Student, UUID> {
 }
