</context:component-scan>

<aop:aspectj-autoproxy/>
<aop:config proxy-target-class="true"/>

在代码中使用如下：

import java.util.List;

import org.apache.commons.collections.CollectionUtils;

import org.aspectj.lang.annotation.Aspect;
import org.aspectj.lang.annotation.Pointcut;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Autowired;

@Aspect
public class PromoteFilter {

private static final Logger logger = LoggerFactory.getLogger(PromoteFilter.class);

@Autowired
GeneralBeanDao beanDao;
@Autowired
PromoteService promoteService;

@Pointcut("execution(* com.group.controller.OrderController.comfirReceipt(..))")
private void privileged() {
}

@AfterReturning("privileged()")
public void access(JoinPoint sp) {

Object[] args = sp.getArgs();
Long id = (Long) args[0];
System.out.println("aop后置通知开始执行：===============================当前订单的Id是："+ id);
