一、创建项目  
项目名称：spring101001  
二、添加jar包  
1.在项目中创建lib目录  
/lib  
2.在lib目录下添加相关spring jar包  
\--用于切面编程  
com.springsource.org.aopalliance-1.0.0.jar  
commons-logging.jar  
junit-4.10.jar  
log4j.jar  
\--用于切面编程  
spring-aop-3.2.0.RELEASE.jar  
spring-beans-3.2.0.RELEASE.jar  
spring-context-3.2.0.RELEASE.jar  
spring-core-3.2.0.RELEASE.jar  
spring-expression-3.2.0.RELEASE.jar  
三、添加配置文件  
1.在项目中创建conf目录  
/conf  
2.在conf目录下添加配置文件  
配置文件名称：applicationContext.xml  
配置文件内容：  
<?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"  
xsi:schemaLocation="  
http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd  
http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd">  
</beans>  
四、创建业务bean  
1.在src目录下创建业务bean包  
包名：cn.jbit.spring101001.service  
2.在包下创建业务bean  
业务bean名称：BookStore.java  
业务bean内容：  
public class BookStore \{  
/\*\*  
\* 进书  
\*/  
public void addBook()\{  
System.out.println("添加图书信息");  
\}  
  
/\*\*  
\* 查找图书  
\*/  
public void findBook()\{  
System.out.println("查找图书信息");  
\}  
\}  
  
bean增强名称：TimeExecute.java  
bean增强内容：  
public interface TimeExecute \{  
public void isActive(boolean flage);  
\}  
  
引介名称：TimeClass.java  
引介内容：  
public class TimeClass extends DelegatingIntroductionInterceptor implements  
TimeExecute \{  
  
private boolean flage;  
@Override  
public void isActive(boolean flage) \{  
this.flage = flage;  
\}  
  
@Override  
public Object invoke(MethodInvocation arg0) throws Throwable \{  
if (flage) \{  
long begin = System.currentTimeMillis();  
Object object = super.invoke(arg0);  
long end = System.currentTimeMillis();  
System.out.println("方法执行时间毫秒："+(end-begin));  
return object;  
\}else\{  
  
return super.invoke(arg0);  
\}  
  
\}  
\}  
五、在核心配置文件中添加配置信息  
  
<bean id="bookstore" class="cn.jbit.spring101001.service.BookStore"></bean>  
  
  
<bean id="timezengqiang" class="cn.jbit.spring101001.service.TimeClass"></bean>  
  
  
<bean id="proxyobject" class="org.springframework.aop.framework.ProxyFactoryBean">  
  
<property name="proxyInterfaces" value="cn.jbit.spring101001.service.TimeExecute"></property>  
  
<property name="proxyTargetClass" value="true"></property>  
  
<property name="interceptorNames" value="timezengqiang"></property>  
  
<property name="target" ref="bookstore"></property>  
</bean>  
六、测试  
1.在项目中创建test目录  
/test  
2.在test目录中创建测试包  
包名：cn.jbit.spring101001.service  
3.在测试包中创建测试类  
测试类名：IntroTest.java  
测试内容：  
public class IntroTest \{  
@Test  
public void testYinJie()\{  
ApplicationContext context = new ClassPathXmlApplicationContext("classpath:applicationContext.xml");  
BookStore bookStore = (BookStore) context.getBean("proxyobject");  
TimeExecute timeExecute = (TimeExecute) bookStore;  
timeExecute.isActive(true);  
bookStore.addBook();  
\}  
\}
