spring AOP练习的时候使用注解时报错，不用就成功

Question

环境
eclipse
jdk1.6
maven

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"

xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

<!-- 开启注解扫描 -->
<context:component-scan base-package="com.cjh.aop2"/>
<!-- 开启aop注解方式，此步骤s不能少，这样java类中的aop注解才会生效 -->
<aop:aspectj-autoproxy/>

</beans>

两个类

        @Component("knight")
    public class BraveKnight {
        public void saying(){
            System.out.println("我是骑士..（切点方法）");
        }
    }

---

@Component("annotationTest")
@Aspect
public class AnnotationTest {
//定义切点
@Pointcut("execution(* *.saying(..))")
public void sayings(){}

@Before("sayings()")
public void sayHello(){
    System.out.println("注解类型前置通知");
}
//后置通知
@After("sayings()")
public void sayGoodbey(){
    System.out.println("注解类型后置通知");
}
//环绕通知。注意要有ProceedingJoinPoint参数传入。
@Around("sayings()")
public void sayAround(ProceedingJoinPoint pjp) throws Throwable{
    System.out.println("注解类型环绕通知..环绕前");
    pjp.proceed();//执行方法
    System.out.println("注解类型环绕通知..环绕后");
}

}

测试类

public static void main(String[] args) {
    ApplicationContext ac = new ClassPathXmlApplicationContext("applicationContext.xml");
    BraveKnight br = (BraveKnight) ac.getBean("knight");
    br.saying();
}

    **报错代码**

类没找到，查下你的spring-core版本
