Spring REST API 没有显示 /players 尽管遵循了教程？

Question

我正在开发 SpringBoot REST API，并且一直在学习教程。我之前遵循过本教程并且一切正常，但现在当我打电话时：

http://localhost:8080/api/players

我收到 404 错误：

{"timestamp":"2021-11-05T15:05:07.850+00:00","status":404,"error":"Not Found","path":"/api/players"}

域：

    @Entity
@Data
@AllArgsConstructor
@NoArgsConstructor
public class Player {

    private @Id
    @GeneratedValue
    Long id;
    private String firstName;
    private String lastName;
    private String email;
    private String bio;


    @Override
    public boolean equals(Object o) {
        if (this == o) return true;
        if (o == null || getClass() != o.getClass()) return false;
        Player player = (Player) o;
        return Objects.equals(id, player.id) &&
                Objects.equals(firstName, player.firstName) &&
                Objects.equals(lastName, player.lastName) &&
                Objects.equals(email, player.email) &&
                Objects.equals(bio, player.bio);
    }

    @Override
    public int hashCode() {

        return Objects.hash(id, firstName, lastName, email, bio);
    }
}

回购：

    public interface PlayerRepository extends CrudRepository<Player, Long> {

}

数据库加载程序：

    @Component
public class DatabaseLoader implements CommandLineRunner {

    private final PlayerRepository repository;

    @Autowired
    public DatabaseLoader(PlayerRepository repository) {
        this.repository = repository;
    }

    @Override
    public void run(String... strings) throws Exception {
        this.repository.save(new Player(1L, "Magnus", "Carlsen", "magnuscarlsen@gmail.com", "I am world champion."));

    }
}

Spring应用程序：

    @SpringBootApplication
public class Application {

    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }
}

应用程序属性：

spring.data.rest.base-path=/api

正如我所说，我真的不明白为什么它不起作用，因为我已经检查了两次并且它应该可以工作，就像我第一次学习本教程时一样：

检查所有 classes 的包。它们应该是您的主要 Application class 所在包的子包。
