看异常是说bean不能实例化,但到底是哪原因,就找不出来了,配置文件是这样的:
<?xml version="1.0" encoding="UTF-8"?>

<aop:after pointcut-ref="mycut" method="doAfter"/>
<aop:around pointcut-ref="mycut" method="doBasicProfiling" />
</aop:aspect>
</aop:config>
</beans>
用作切面的类:
package cn.itcast.service;
import org.aspectj.lang.ProceedingJoinPoint;
public class MyInterceptor2 {
public void doAccessCheck(String name) {
System.out.println("前置通知:" + name);
}
public void doAfterReturning(String result) {
System.out.println("后置通知:" + result);
}
public void doAfter() {
System.out.println("最终通知");
}
public void doAfterThrowing(Exception e) {
System.out.println("例外通知:" + e);
}
public Object doBasicProfiling(ProceedingJoinPoint pjp) throws Throwable {
// if(){ 判断用户是否有权限
System.out.println("进入方法");
Object result = pjp.proceed();
// }
System.out.println("退出方法");
return result;
}
}
以下是所报出的异常,检查了很久,发现目录都没写错,类也是正确的:
