Re: [aspectj-dev] A little help with perthis/pertarget ...

["Dan Bush" <dan.bush@xxxxxxxxx>]

Ok tried it again:

package com.xxx.aspect;

import org.slf4j.*;
import javax.ejb.*;
import com.xxx.ejb.stateless.*;
import java.util.*;

/**
* Profiles
*/
aspect ProfileAspect perthis(execution(* *Service.* (..))) {

    private long start;

        private static final Logger LOG = LoggerFactory
        .getLogger("com.ing.uds.aspect.ProfileAspect");

                pointcut services(): (execution(* *Service.* (..)));

    before(): services() {
     start =System.currentTimeMillis();
    }

    after(): services() {
        LOG.debug("{}|{}", thisJoinPoint, Long.toString(System.currentTimeMillis()-start));
        }

}

The advise is no longer executing.

does not work for you?
