IHello.java HelloSpeaker.java文件同 ThrowAdviceDemo相同

 

LogAspect.java内容：

package onlyfun.caterpillar;

import java.util.logging.Level;
import java.util.logging.Logger;

import org.aspectj.lang.JoinPoint;

public class LogAspect {
    private Logger logger =
            Logger.getLogger(this.getClass().getName());
   
    public void before(JoinPoint jointPoint) {
        logger.log(Level.INFO, "method starts..." +
            jointPoint.getSignature().getDeclaringTypeName() +
            "." + jointPoint.getSignature().getName());
    }

    public void afterReturning(JoinPoint jointPoint) {
        logger.log(Level.INFO, "method ends..." +
            jointPoint.getSignature().getDeclaringTypeName() +
            "." + jointPoint.getSignature().getName());
    }

    public void afterThrowing(JoinPoint jointPoint,
                              Throwable throwable) {
        logger.log(Level.INFO, "Logging that a " + throwable +
            "/nException was thrown in..." +
            jointPoint.getSignature().getDeclaringTypeName() +
            "." + jointPoint.getSignature().getName());
    }
}
