Anatres Sample

Getting Start

Firstly, define an AntaresManifestAdvice to tell Antares how to collect passengers and which FactoryBean class should be used to create the bean instance.

@Target({ElementType.TYPE})
@Retention(RetentionPolicy.RUNTIME)
@AntaresManifestAdvice(factoryClass = FooFactoryBean.class)
public @interface Foo {
    // Annotation methods
}

Secondly, implement your own FactoryBean which will create the bean instance.

public class FooFactoryBean extends AntaresFactoryBean {
    @Override
    public Object getObject() throws Exception {
        // Create the bean instance here
        return getObjectType().newInstance();
    }
}

Thirdly, use your own annotation in your code.

@Foo
public class MyBean { }

Put it together.

@AntaresScan
@SpringBootApplication
public class MyApp {
    public static void main(String[] args) {
        SpringApplication.run(MyApp.class, args);
    }
}

@Target({ElementType.TYPE})
@Retention(RetentionPolicy.RUNTIME)
@AntaresManifestAdvice(factoryClass = FooFactoryBean.class)
public @interface Foo {
    // Annotation methods
}

class FooFactoryBean extends AntaresFactoryBean {
    @Override
    public Object getObject() throws Exception {
        // Create the bean instance here
        return getObjectType().newInstance();
    }
}

@Foo
public class MyBean { }

@Service
class MyService {
    @Autowired
    private MyBean myBean;
}
