java-用@aspect注解方式無法實現切面功能

用@aspect注解方式無法實現切面功能

用@aspect注解的方式實現切面，但是無發效果，代碼如下，求大神解答

業務類

 package com.aop_spring;


public class Business implements IBusiness, IBusiness2 {   

    @Override   
    public boolean doSomeThing() {   
        System.out.println("執行業務邏輯");   
        return true;   
    }   

    @Override   
    public void doSomeThing2() {   
        System.out.println("執行業務邏輯2");   
    }   

}   

切面代碼：

 package com.aop_spring;

import org.aspectj.lang.annotation.Aspect;
import org.aspectj.lang.annotation.Before;

@Aspect
public class SpringAspect {

    @Before("execution(* * com.aop_spring.Business.*(..))")
    public void before(){
        System.out.println("before");
    }
}

spring配置文件

<beans
    xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

    <context:component-scan base-package="com.*" annotation-config="true"/>

    <aop:aspectj-autoproxy/>    

    <bean id="business" class="com.aop_spring.Business">
    </bean>

</beans>

測試代碼：

 package com.aop_spring;

import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

public class Test {
     public static void main(String[] args){
            ApplicationContext appCtx = new ClassPathXmlApplicationContext("applicationContext.xml");
            ((Business) appCtx.getBean("business")).doSomeThing();
        }
}

包路徑：

運行結果：
執行業務邏輯

最佳回答：

@Aspect上面注解一個@Component試試
