Below is my code. I want to inject the "inter" field. Why is the
output null?
import static java.lang.annotation.ElementType.FIELD;
import static java.lang.annotation.ElementType.METHOD;
import static java.lang.annotation.ElementType.PARAMETER;
import static java.lang.annotation.RetentionPolicy.RUNTIME;
import java.lang.annotation.Retention;
import java.lang.annotation.Target;
import com.google.inject.AbstractModule;
import com.google.inject.BindingAnnotation;
import com.google.inject.Guice;
import com.google.inject.Inject;
import com.google.inject.Injector;
public class AnnotationDemo2 {
@Inject @MyAnnotation public Inter inter;
public static void main(String[] args) {
Injector injector = Guice.createInjector(new AbstractModule(){
@Override
protected void configure() {
bind(Inter.class).annotatedWith(MyAnontation.class).to
(Type.class);
}
});
AnnotationDemo2 demo2 = new AnnotationDemo2();
System.out.println(demo2.inter);
}
}
@BindingAnnotation @Target({ FIELD, PARAMETER, METHOD }) @Retention
(RUNTIME)
@interface MyAnnotation{
}
interface Inter{
}
class Type implements Inter{
}
