package pl.krywion.movies.app;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
@RestController
@RequestMapping("/api/v1/movies")
public class MovieController {
@GetMapping
public String allMovies() {
return "All Movies!";
}
}
My main class
package pl.krywion.movies;
import org.springframework.boot.SpringApplication;

I don't know how to fix it, I am a Spring beginner
I tried using @ComponentScan annotation, and moving MovieApplication Java class to package above or moving it ot the same package as controller
There is an issue with component scanning in spring 3.0.3: https://github.com/spring-projects/spring-boot/issues/34379
The issue occurs when running your application not as a .jar. If your project structure has directory elements whose names contain a characters that would be encoded in a URL, component scanning will not work as expected.
You can change your application's path to remove those characters. Or you downgrade to 3.0.2 or upgrade to 3.0.4, available since March 04, 2023.
