Using Spring I've had some issues with doing a dependency injection on an annotated Aspect class. CacheService is injected upon the Spring context's startup, but when the weaving takes place, it says that the cacheService is null. So I am forced to relook up the spring context manually and get the bean from there. Is there another way of going about it?

Here is an example of my Aspect:

import org.apache.log4j.Logger;
import org.aspectj.lang.ProceedingJoinPoint;
import org.aspectj.lang.annotation.Around;
import org.aspectj.lang.annotation.Aspect;
import com.mzgubin.application.cache.CacheService;

@Aspect
public class CachingAdvice {

  private static Logger log = Logger.getLogger(CachingAdvice.class);

  private CacheService cacheService;

  @Around("execution(public *com.mzgubin.application.callMethod(..)) &&"
    		+ "args(params)")
    public Object addCachingToCreateXMLFromSite(ProceedingJoinPoint pjp, InterestingParams params) throws Throwable {
    log.debug("Weaving a method call to see if we should return something from the cache or create it from scratch by letting control flow move on");

    Object result = null;
    if (getCacheService().objectExists(params))}{
      result = getCacheService().getObject(params);
    } else {
      result = pjp.proceed(pjp.getArgs());
      getCacheService().storeObject(params, result);
    }
    return result;
  }

  public CacheService getCacheService(){
    return cacheService;
  }

  public void setCacheService(CacheService cacheService){
    this.cacheService = cacheService;
  }
}
