I have this spring configuration:
@Lazy
@Configuration
public class MyAppConfig {
@Foo @Bean
public IFooService service1() { return new SpecialFooServiceImpl(); }
}
How can I get a list of all beans that are annotated with @Foo
?
Note: @Foo
is a custom annotation defined by me. It's not one of the "official" Spring annotations.
[EDIT] Following the suggestions of Avinash T., I wrote this test case:
import static org.junit.Assert.*;
import java.lang.annotation.ElementType;
import java.lang.annotation.RetentionPolicy;
import java.lang.annotation.Target;
import java.lang.annotation.Retention;
import java.lang.reflect.Method;
import java.util.Map;
import org.junit.Test;
import org.springframework.beans.factory.config.BeanDefinition;
import org.springframework.context.annotation.AnnotationConfigApplicationContext;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.Lazy;
public class CustomAnnotationsTest {
@Test
public void testFindByAnnotation() throws Exception {
AnnotationConfigApplicationContext appContext = new AnnotationConfigApplicationContext( CustomAnnotationsSpringCfg.class );
Method m = CustomAnnotationsSpringCfg.class.getMethod( "a" );
assertNotNull( m );
assertNotNull( m.getAnnotation( Foo.class ) );
BeanDefinition bdf = appContext.getBeanFactory().getBeanDefinition( "a" );
// Is there a way to list all annotations of bdf?
Map<String, Object> beans = appContext.getBeansWithAnnotation( Foo.class );
assertEquals( "[a]", beans.keySet().toString() );
}
@Retention( RetentionPolicy.RUNTIME )
@Target( ElementType.METHOD )
public static @interface Foo {
}
public static class Named {
private final String name;
public Named( String name ) {
this.name = name;
}
@Override
public String toString() {
return name;
}
}
@Lazy
@Configuration
public static class CustomAnnotationsSpringCfg {
@Foo @Bean public Named a() { return new Named( "a" ); }
@Bean public Named b() { return new Named( "b" ); }
}
}
but it fails with org.junit.ComparisonFailure: expected:<[[a]]> but was:<[[]]>
. Why?
