I am trying to create a new starter. I have a business module, say ProjectManager, that contains some classes annotated with @Component. Following the tutorial, I created an autoconfigure module, it contains an AutoConfiguration class. Firstly, I tried to use @ComponentSan to find the beans in my business module.
@ComponentScan(value = {"com.foo.project"})
@ConditionalOnClass({Project.class})
@Configuration
public class ProjectAutoConfiguration {
....
}
But it doesn't work. I have to add additional configuration class as below:
@Configuration
@ComponentScan(value = {"com.foo.project"})
@MapperScan(value = {"com.foo.project"})
public class ProjectConfig {
}
And then import it into AutoConfiguration class like below:
@Import(ProjectConfig.class)
@ConditionalOnClass({Project.class})
@Configuration
public class ProjectAutoConfiguration {
....
}
That works. But according to the spring doc.
auto-configuration is implemented with standard @Configuration classes
So my question is, Why @ComponentScan doesn't work here ? Did I make something wrong? Or it is by design ?
you have to use the compentscan annotation into the main class. Here a sample code:
@SpringBootApplication
@ComponentScan("com.foo.project")
public class MainApplication extends SpringBootServletInitializer {
@Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
return application.sources(MainApplication.class);
}
public static void main(String[] args) {
new MainApplication().configure(new SpringApplicationBuilder(MainApplication.class)).run(args);
}
}
Cheers
