1.定義介面Perform

package com.show;
/**
 * Created by kenneth on 2017/4/6.
 */
public interface Perform {
    void sing();
}

2.介面Perform的實現類Boy

package com.show;
/**
 * Created by kenneth on 2017/4/6.
 */
public class Boy implements Perform {
    @Override
public void sing() {
        System.out.println("男孩在唱歌
 
");
}
}

3.定義通知PerformHelper

package com.show;
/**
 * Created by kenneth on 2017/4/6.
 */
public class PerformHelper {
    public void beforePerform() {
        System.out.println("表演之前要整理衣服");
}

    public void afterPerform() {
        System.out.println("表演之後要行禮");
}
}

4.Spring配置檔案

<?xml version
 
="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:aop="http://www.springframework.org/schema/aop"
xsi:schemaLocation="http://www.springframework.org/schema/beans
       http://www.springframework.org/schema/beans/spring-beans.xsd
 
       http://www.springframework.org/schema/aop
       http://www.springframework.org/schema/aop/spring-aop.xsd">
<!--目標物件-->
<bean id="boy" class="com.show.Boy"/>
<!--切面-->
<bean id="performHelper" class="com.show.PerformHelper"/>
<!--配置切入點-->
<aop:config>
        <aop:pointcut id="pointcut" expression="execution(public * *..Perform.sing(..))"/>
        <aop:aspect ref="performHelper">
            <aop:before method="beforePerform" pointcut-ref="pointcut"/>
            <aop:after method="afterPerform" pointcut-ref="pointcut"/>
        </aop:aspect>
    </aop:config>
</beans>

5.測試類

package com.show;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
/**
 * Created by kenneth on 2017/4/6.
 */
public class Test {
    public static void main(String[] args) {
        ApplicationContext context = new ClassPathXmlApplicationContext("ApplicationContext.xml");
Perform performer = (Perform) context.getBean("boy");
performer.sing();
}
}
