Spring autowired bean for @Aspect aspect is null

Question

I have the following spring configuration:

Answer 1

Configuring @Autowired with java config only (so no XML based configuration) requires a bit of extra work than just adding @Configuration to the class, as it also needs the aspectOf method.

What worked for me was creating a new class:

@Component
public class SpringApplicationContextHolder implements ApplicationContextAware {

    private static ApplicationContext applicationContext = null;

    public static ApplicationContext getApplicationContext() {
        return applicationContext;
    }

    @Override
    public void setApplicationContext(ApplicationContext applicationContext) throws BeansException {
       this.applicationContext = applicationContext;
    }
}

And then use that in you aspect in conjunction with using @DependsOn @Configured and @Autowired:

@DependsOn("springApplicationContextHolder")
@Configuration
@Aspect
public class SomeAspect {

    @Autowired
    private SomeBean someBean;

    public static SomeAspect aspectOf() {
        return SpringApplicationContextHolder.getApplicationContext().getBean(SomeAspect.class);
    }

The @DependsOn is needed because spring can't determine the dependency because the bean is used staticly.
