this is the main class

@SpringBootApplication(exclude = {DataSourceAutoConfiguration.class, SecurityAutoConfiguration.class})
@ComponentScan("com.alibou.security.user")
public class SecurityApplication {

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

}

and this is the structure of the project

enter image description here

this is one controller sample

@RestController
public class Controller {

    @GetMapping("/hello")
    public String helloWorld() {
        return "Hello World";
      }
}

and this is an input from POSTMAN

nothing is working, i swear i didnt have this problems years ago, now even the most simple thing is not working anymore.

Any hint?

Solution

  • Baeldung has a good explanation on how these annotations work here: https://www.baeldung.com/spring-component-scanning.

    Essentially, (from their site):

    We use the @SpringBootApplication annotation, but it's a combination of three annotations:

    @Configuration
@EnableAutoConfiguration
@ComponentScan

    Only the location of the configuration class matters, as component scanning starts from its package by default.

    Since you have used the @SpringBootApplication, the scanning will start from there, so I dont think you need to have the @ComponentScan annotation here. Unless you are trying to achieve something else that you did not mention on the question.
