spring framework面向切面编程示例（xml配置）：spring-aop

示例代码：http://download.csdn.net/detail/u010476739/9922458

工具：spring framework 4.2.4、maven

使用xml配置实现spring-aop

1.pom依赖

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">  <modelVersion>4.0.0</modelVersion>  <groupId>com.jackletter</groupId>  <artifactId>springaopxml</artifactId>  <version>0.0.1-SNAPSHOT</version>  <name>this is name</name>  <description>this is desc</description>    <properties>  <spring.version>4.2.4.RELEASE</spring.version>  </properties>    <dependencies>         <!-- Spring Core -->        <!-- http://mvnrepository.com/artifact/org.springframework/spring-core -->        <dependency>            <groupId>org.springframework</groupId>            <artifactId>spring-core</artifactId>            <version>${spring.version}</version>        </dependency>                 <!-- Spring Context -->        <!-- http://mvnrepository.com/artifact/org.springframework/spring-context -->        <dependency>            <groupId>org.springframework</groupId>            <artifactId>spring-context</artifactId>            <version>${spring.version}</version>        </dependency>                <!-- Spring Aop -->        <!-- http://mvnrepository.com/artifact/org.springframework/spring-aop/4.3.4.RELEASE -->        <dependency>    <groupId>org.springframework</groupId>    <artifactId>spring-aop</artifactId>    <version>${spring.version}</version></dependency><dependency>    <groupId>org.aspectj</groupId>    <artifactId>aspectjweaver</artifactId>    <version>1.8.10</version></dependency>             </dependencies></project>

2.spring配置文件（applicationContext.xml）

<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="person" class="bean.Person" /><bean id="dog" class="bean.Dog" /><bean id="cat" class="bean.Cat" /><aop:config><aop:aspect ref="person"><aop:pointcut expression="execution(* bean.Animate.show())" id="show"/><!-- <aop:before method="showBefore" pointcut="execution(* bean.Animate.show())"/> --><aop:before method="showBefore" pointcut-ref="show"/><aop:after-returning method="showAfter" pointcut-ref="show"/><aop:after-throwing method="showThrow" pointcut-ref="show"/><aop:around method="showArround" pointcut-ref="show"/></aop:aspect></aop:config></beans>

3.代码

Animate

package bean;public interface Animate {public String show() throws Exception;}

Cat

package bean;public class Cat implements Animate {public String show() {return "i'm cat";}}

Dog

package bean;public class Dog implements Animate{public String show() throws Exception {//throw new Exception("ko");return "i'm dog";}}

Person

package bean;import org.aspectj.lang.ProceedingJoinPoint;public class Person {public void showBefore(){System.out.println("before run...");}public void showAfter(){System.out.println("after run...");}public Object showArround(ProceedingJoinPoint point) throws Throwable{System.out.println("arround start...");Object obj=point.proceed();System.out.println("arround end...");return obj;}public void showThrow(){System.out.println("throw run...");}}

App

package springaopxml;import org.springframework.context.ApplicationContext;import org.springframework.context.support.ClassPathXmlApplicationContext;import bean.Animate;public class App {public static void main(String[] args) throws Exception {ApplicationContext context=new ClassPathXmlApplicationContext("applicationContext.xml");Animate ani=(Animate) context.getBean("dog");System.out.print(ani.show());}}
