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;

@Override

public void sayHello() {

// TODO 自动生成的方法存根

System.out.println(Hello);

}

@Override

public 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：

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.xsd

http://www.springframework.org/schema/context

http://www.springframework.org/schema/context/spring-context-3.0.xsd

http://www.springframework.org/schema/tx

http://www.springframework.org/schema/tx/spring-tx-3.0.xsd

http://www.springframework.org/schema/aop

http://www.springframework.org/schema/aop/spring-aop-3.0.xsd">

Hello,china!

你好,中国欢迎您!

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

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.xsd

http://www.springframework.org/schema/context

http://www.springframework.org/schema/context/spring-context-3.0.xsd

http://www.springframework.org/schema/tx

http://www.springframework.org/schema/tx/spring-tx-3.0.xsd

http://www.springframework.org/schema/aop

http://www.springframework.org/schema/aop/spring-aop-3.0.xsd">

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
