Spring Dependency Injection into JPA entity listener

Question

I need to have a Spring dependency injected into a JPA entity listener. I know I can solve this using @Configurable and Spring's AspectJ weaver as javaagent, but this seems like a hacky solution. Is there any other way to accomplish what I'm trying to do?

Another trick is to implement an utility class with static method that helps you to use Spring beans everywhere, not only in managed classes:

@Component
public final class BeanUtil {

    private static ApplicationContext context;

    private BeanUtil(ApplicationContext context) {
        BeanUtil.context = context;
    }

    public static <T> T getBean(Class<T> clazz) throws BeansException {

        Assert.state(context != null, "Spring context in the BeanUtil is not been initialized yet!");
        return context.getBean(clazz);
    }
}
