我正在关注本教程（https://www.youtube.com/watch?v=Hu-cyytqfp8），并尝试在Spring Boot中连接到远程服务器上的MongoDB。运行应用程序时，我收到以下消息。

说明：com.mongotest.demo.Seeder中构造函数的参数0需要找不到“ com.mongotest.repositories.StudentRepository”类型的Bean。

行动：考虑在配置中定义一个类型为“ com.mongotest.repositories.StudentRepository”的bean。

    @Document(collection = "Students")
    public class Student {

        @Id
        private String number;
        private String name;
        @Indexed(direction = IndexDirection.ASCENDING)
        private int classNo;

    //Constructor and getters and setters.
    }

    ================================

    @Repository
    public interface StudentRepository extends MongoRepository<Student, String>{

    }

    @Component
    @ComponentScan({"com.mongotest.repositories"})

        private StudentRepository studentRepo;

        public Seeder(StudentRepository studentRepo) {
            super();
            this.studentRepo = studentRepo;
        }

        @Override
        public void run(String... args) throws Exception {
            // TODO Auto-generated method stub
