I-Stack-Trace für folgenden Code bin immer,

public interface SequenceDAO { 

    public Sequence getSequence(String sequenceId); 

    public int getNextValue(String sequenceId); 
}

Iam neu zu springen und ich lerne Frühling ohne Anmerkungen, also wenn jemand kann mir sagen, was falsch hier passiert

jede Hilfe ist apperitiert.

Ihr Kontext init sollte dies mag:

ApplicationContext aContext = new AnnotationConfigApplicationContext(ConcertConfig.class); 
@Configuration 
@EnableAspectJAutoProxy 
@ComponentScan 
public class ConcertConfig { 

}
