Sample Project
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;
}
