SpringXML方式实现AOP demo

1、新建一个java的工程，导入spring需要的jar包与开发切面需要的jar包。

dist\spring.jar
lib\jakarta-commons\commons-logging.jar
如果使用了切面编程(AOP),还需要下列jar文件
lib/aspectj/aspectjweaver.jar和aspectjrt.jar
lib/cglib/cglib-nodep-2.1_3.jar
如果使用了JSR-250中的注解,如@Resource/@PostConstruct/@PreDestroy,还需要下列jar文件
lib\j2ee\common-annotations.jar

2、Person.java

package cn.ehoo.bean;
/**
 * @author whp
 * @Email [email protected]
 * @Jan 4, 2011
 * 
 */
public class Person {
	private Long id;
	private String name;

	public Long getId() {
		return id;
	}

	public void setId(Long id) {
		this.id = id;
	}

	public String getName() {
		return name;
	}

	public void setName(String name) {
		this.name = name;
	}

}

2、PersonService.java 与PersonServiceBean.java

PersonService.java

package cn.ehoo.service;

import cn.ehoo.bean.Person;

/**
 *@author whp
 *@Email [email protected]
 *@Jan 4, 2011
 *
 */
public interface PersonService {

	public void save(Person person);

}

PersonServiceBean.java

package cn.ehoo.service.impl;


import cn.ehoo.bean.Person;
import cn.ehoo.service.PersonService;

/**
 * @author whp
 * @Email [email protected]
 * @Jan 4, 2011
 * 
 */
public class PersonServiceBean implements PersonService {
	private String user;

	public String getUser() {
		return user;
	}

	public void setUser(String user) {
		this.user = user;
	}

	public PersonServiceBean() {
	}

	public PersonServiceBean(String user) {
		super();
		this.user = user;
	}

	public void save(Person person) {
		System.out.println("执行PerServiceBean的save方法");
		//throw new RuntimeException("======");
	}
}

3、MyInterceptor.java

package cn.ehoo.service.impl;

import org.aspectj.lang.ProceedingJoinPoint;

/**
 * @author whp
 * @Email [email protected]
 * @Jan 4, 2011
 * 
 */
public class MyInterceptor {
	private void anyMethod() {
	}
	public void doAccessCheck() {
		System.out.println("执行前置通知");
	}

	public void doReturnCheck() {
		System.out.println("执行后置通知");
	}

	public void doReleaseAction() {
		System.out.println("执行最终通知");
	}

	public void doExceptionAction() {
		System.out.println("执行例外通知");
	}

	public Object doBasicProfiling(ProceedingJoinPoint pjp) throws Throwable {
		System.out.println("执行环绕通知");
		Object retule = pjp.proceed();
		System.out.println("退出环绕通知");
		return retule;
	}

}

4 在src下对beans.xml进行配置

<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"
	xsi:schemaLocation="http://www.springframework.org/schema/beans
           http://www.springframework.org/schema/beans/spring-beans-2.5.xsd
           http://www.springframework.org/schema/context
           http://www.springframework.org/schema/context/spring-context-2.5.xsd
           http://www.springframework.org/schema/aop 
           http://www.springframework.org/schema/aop/spring-aop-2.5.xsd">
	<bean name="personService" class="cn.ehoo.service.impl.PersonServiceBean" />
	<bean name="myInterceptor" class="cn.ehoo.service.impl.MyInterceptor" />
	<aop:config>
		<aop:aspect id="myaop" ref="myInterceptor">
			<aop:pointcut id="mycut" expression="execution(* cn.ehoo.service.impl.PersonServiceBean.*(..))" /><!--切入点表达式 -->
			<aop:before pointcut-ref="mycut" method="doAccessCheck" /><!--前置通知 -->
			<aop:after-returning pointcut-ref="mycut" method="doReturnCheck" /><!--后置通知 -->
			<aop:after-throwing pointcut-ref="mycut" method="doExceptionAction" /><!--例外通知 -->
			<aop:after pointcut-ref="mycut" method="doReleaseAction" /><!--执行最终通知 -->
			<aop:around pointcut-ref="mycut" method="doBasicProfiling" /><!--执行环绕通知-->
		</aop:aspect>
	</aop:config>

</beans>

5、测试类

package junit.test;

import org.junit.AfterClass;
import org.junit.BeforeClass;
import org.junit.Test;
import org.springframework.context.support.AbstractApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

import cn.ehoo.bean.Person;
import cn.ehoo.service.PersonService;

/**
 * @author whp
 * @Email [email protected]
 * @Jan 4, 2011
 * 
 */
public class AOPTest {
	static PersonService personService;
	@BeforeClass
	public static void setUpBeforeClass() throws Exception {
		AbstractApplicationContext cxt = new ClassPathXmlApplicationContext("beans.xml");
		personService = (PersonService) cxt.getBean("personService");
	}

	/**
	 * @author whp
	 * @Email [email protected]
	 * @Jan 4, 2011
	 * 
	 */
	
	public static void main(String[] args) {
		try {
			setUpBeforeClass();
		} catch (Exception e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}
	}
	@Test
	public void saveTest() {
		personService.save(new Person());
	}

	@AfterClass
	public static void tearDownAfterClass() throws Exception {
	}
}
