Spring中MethodBeforeAdvice，AfterReturningAdvice类对消息的管理和使用

Spring中对消息机制的使用，我们首先使用继承类的方法完成
通过使用idea工具下的Maven聚合项目方式来编写的案例
项目整体架构

父项目的pom.xml中定义了所有的包

因为我们只是了AOP切面技术完成该案例，所有不需要完全导入父项目的JAR包。

在dome包中创建2个简单的类，为了之后调用该类下的方法来为消息机制做准备

package com.zxf.demo;

public class Demo1 {
    public void demo1(){
        System.out.println("demo1");
    }
    public void demo2(){
        System.out.println("demo2");
    }
    public void demo3(){
        System.out.println("demo3");
    }
}

package com.zxf.demo;

public class Demo2 {
    public void f(){
        System.out.println("f()");
    }
}

编写消息机制，本案例通过继承类放是完成

package com.zxf.advice;

import org.springframework.aop.AfterReturningAdvice;

import java.lang.reflect.Method;

public class MyAfterAdvice implements AfterReturningAdvice {
    public void afterReturning(Object o, Method method, Object[] objects, Object o1) throws Throwable {
        System.out.println("执行后发出的通知...");
    }
}

package com.zxf.advice;

import org.springframework.aop.MethodBeforeAdvice;

import java.lang.reflect.Method;

public class MyBeforeAdvice implements MethodBeforeAdvice {
    public void before(Method method, Object[] objects, Object o) throws Throwable {
               System.out.println("执行前发出的通知。。");
    }
}

下面来完成Spring核心配置文件的编写
applicationContext.mxl

<?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">
<bean id="mybefore" class="com.zxf.advice.MyBeforeAdvice"/>
    <bean id="after" class="com.zxf.advice.MyAfterAdvice"/>
<aop:config>
       <aop:pointcut id="aop1" expression="execution(* com.zxf.demo.*.*(..))"/>
       <!--* 代表所有的意思 -->
       <!--com.zxf.demo.Demo1.*(..)) Demo1类下的所有方法 -->
       <!--com.zxf.demo.*.*(..)) demo包下的所有类和方法 -->
    <aop:advisor advice-ref="after" pointcut-ref="aop1"/>
    <aop:advisor advice-ref="mybefore" pointcut-ref="aop1"/>
</aop:config>
<bean id="demo1" class="com.zxf.demo.Demo1"/>
<bean id="demo2" class="com.zxf.demo.Demo2"/>
</beans>

最后一个junit的方式测试类

package com.zxf;

import com.zxf.demo.Demo1;
import com.zxf.demo.Demo2;
import org.junit.Test;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

public class Test1 {
    @Test
    public void test1(){
        ApplicationContext ac=new ClassPathXmlApplicationContext("applicationContext.xml");
        Demo1 d_1 = ac.getBean("demo1", Demo1.class);
        d_1.demo1();
        d_1.demo2();
        d_1.demo3();
        Demo2 d_2 = ac.getBean("demo2", Demo2.class);
          d_2.f();

    }
}

运行结果
