一、eclipse新建java项目取名SpringTest

二、导入sping包到构建路径

还需要aspectjweaver.jar

三、创建java类（当然先要创建各种包）

IHelloService.java

package com.zjptcc.wxw.spring.hello;public interface IHelloService {public void sayHello();public void sayChinaHello();}

HelloServiceImpl.java

package com.zjptcc.wxw.spring.hello;public class HelloServiceImpl implements IHelloService {private String Hello;private String ChinaHello;@Overridepublic void sayHello() {// TODO 自动生成的方法存根System.out.println(Hello);}@Overridepublic void sayChinaHello() {// TODO 自动生成的方法存根System.out.println(ChinaHello);}public String getHello() {return Hello;}public void setHello(String hello) {Hello = hello;}public String getChinaHello() {return ChinaHello;}public void setChinaHello(String chinaHello) {ChinaHello = chinaHello;}}

SimpleHelloBean.java

package com.zjptcc.wxw.spring.hello;public class SimpleHelloBean {public void sayHello(){System.out.println("Hello World!");}
}

AopTest.java

package com.zjptcc.wxw.spring.hello;import org.aspectj.lang.annotation.AfterReturning;
import org.aspectj.lang.annotation.Aspect;
import org.aspectj.lang.annotation.Before;
import org.aspectj.lang.annotation.Pointcut;@Aspect
public class AopTest {/*Pointcut for sayHello*/@Pointcut("execution(* *.sayHello())")public void hellopoint() {}@Before("hellopoint()")public void beforehello() {System.out.println("接下去调用sayHello()......");}@AfterReturning("hellopoint()")public void afterhello() {System.out.println("函数sayHello()执行结束......");}/*Pointcut for sayChinaHello*/@Pointcut("execution(* *.sayChinaHello())")public void helloChinapoint() {}@Before("helloChinapoint()")public void beforehelloChina() {System.out.println("接下去调用sayChinaHello()......");}@AfterReturning("helloChinapoint()")public void afterhelloChina() {System.out.println("函数sayChinaHello()执行结束......");}
}

四、配置文件

在src目录下创建resources目录，并在其下建立hello-beans.xml内容如下：

<?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:context="http://www.springframework.org/schema/context"xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx"xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsdhttp://www.springframework.org/schema/contexthttp://www.springframework.org/schema/context/spring-context-3.0.xsdhttp://www.springframework.org/schema/txhttp://www.springframework.org/schema/tx/spring-tx-3.0.xsdhttp://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.0.xsd"><context:annotation-config/> <aop:aspectj-autoproxy /><bean id="helloService" class="com.zjptcc.wxw.spring.hello.HelloServiceImpl"><property name="Hello"><value>Hello,china!</value></property><property name="ChinaHello"><value>你好,中国欢迎您!</value></property></bean><bean id="SimpleHelloBean" class="com.zjptcc.wxw.spring.hello.SimpleHelloBean"></bean><bean id="aopTest" class="com.zjptcc.wxw.spring.hello.AopTest" /></beans>

五、测试

测试程序TestHelloService.java如下：

package com.zjptcc.wxw.spring.test;import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;import com.zjptcc.wxw.spring.hello.IHelloService;
import com.zjptcc.wxw.spring.hello.SimpleHelloBean;public class TestHelloService {/*** @param args*/private static ApplicationContext ctx;public static void main(String[] args) {// TODO 自动生成的方法存根ctx = new ClassPathXmlApplicationContext("resources/hello-beans.xml");//用接口IHelloService helloWorld = (IHelloService) ctx.getBean("helloService");helloWorld.sayHello();helloWorld.sayChinaHello();System.out.println("------------------------------------------------------------------------------------");//用类SimpleHelloBean SimpleHello = (SimpleHelloBean) ctx.getBean("SimpleHelloBean");SimpleHello.sayHello();}}

运行结果如下：

六、利用配置文件实现AOP

java类

package com.zjptcc.wxw.spring.person;
public class PersonService {private String name;public void setName(String name) {this.name = name;}public void info(){System.out.println("此人姓名为："+name);}public String getName(){return name;}
}

package com.zjptcc.wxw.spring.person;public class PersonAop {public void before_info() {System.out.println("接下去,调用info()显示人名......");}public void after_info() {System.out.println("调用info()结束......");}public void after_get() {System.out.println("调用getName()结束......");}}

resources/person-beans.xml

<?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:context="http://www.springframework.org/schema/context"xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx"xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsdhttp://www.springframework.org/schema/contexthttp://www.springframework.org/schema/context/spring-context-3.0.xsdhttp://www.springframework.org/schema/txhttp://www.springframework.org/schema/tx/spring-tx-3.0.xsdhttp://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.0.xsd"><context:annotation-config /><aop:aspectj-autoproxy /><bean id="personService" class="com.zjptcc.wxw.spring.person.PersonService"><property name="name"><value>露茜</value></property></bean><!--定义切面 --><bean id="personaop" class="com.zjptcc.wxw.spring.person.PersonAop" /><aop:config><aop:aspect ref="personaop"><aop:pointcut id="infopoint" expression="execution(* *.info(..))" /><aop:before pointcut-ref="infopoint" method="before_info" /><aop:after pointcut-ref="infopoint" method="after_info" /></aop:aspect><aop:aspect ref="personaop"><aop:pointcut id="getpoint" expression="execution(* *.getName(..))" /><aop:after pointcut-ref="getpoint" method="after_get" /></aop:aspect></aop:config></beans>

测试

package com.zjptcc.wxw.spring.test;import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;import com.zjptcc.wxw.spring.person.PersonService;public class TestPersonService {/*** @param args*/private static ApplicationContext ctx;public static void main(String[] args) {// TODO 自动生成的方法存根ctx = new ClassPathXmlApplicationContext("resources/person-beans.xml");PersonService p = (PersonService) ctx.getBean("personService");p.info();System.out.println(p.getName());}}

运行
