Spring 2.0 AOP Simple 예제 

1.        필요한 파일을 클래스 패스에 추가한다. 
        C:\java\spring-framework-2.5.3\dist\spring.jar 
        common-logging.jar파일을 다운로드(http://commons.apache.org/logging/) 
commons-logging-1.1.1.jar 파일을 클래스패스에 추가 
        AOP를 위해 C:\java\spring-framework-2.5.3\\lib\aspectJ 아래 aspectjrt.jar 와 aspectjrt.jar 파일을 클래스 패스에 추가 

2.        springaop라는 자바프로젝트를 작성 후 Animal.java 인터페이스를 작성 

[Animal.java] 
package springaop; 

public interface Animal { 
    public void walwal(); 
} 

3.        Tomdog.java 인터페이스 구현 클래스 제공 
  
        [TomDog.java] 
package springaop; 

public class TomDog implements Animal { 
    public void walwal() { 
            System.out.println("I'm Tomdog..."); 
    } 
} 

4.        Aspect 작성 

[AnimalAOP.java] 
package springaop; 

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 AnimalAOP { 
    @Pointcut("execution(public * Animal.walwal(..))") 
    public void greeting() {            
    } 
    
    @Before("greeting()") 
    public void hi() { 
            System.out.println("Hi ... "); 
    } 
    
    @AfterReturning("greeting()") 
    public void doBeforeOne() { 
            System.out.println("Good Bye ~~~"); 
    } 
} 


5.        Application-Context.xml 작성 

[application-context.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"> 

        <!-- this is the object that will be proxied by Spring's AOP infrastructure --> 
      <bean id="tomdog" class="springaop.TomDog" /> 
      
      <aop:aspectj-autoproxy /> 
      
      <!-- this is the actual advice itself --> 
      <bean id="animalAOP" class="springaop.AnimalAOP" /> 
  

</beans> 

6.        TestClient 작성 

[TestClient.java] 
package springaop; 

import org.springframework.beans.factory.BeanFactory; 
import org.springframework.context.support.FileSystemXmlApplicationContext;; 

public class TestClient { 
    public static void main(String[] args) { 
            BeanFactory bean = new FileSystemXmlApplicationContext("C:\\java\\Tomcat 5.5\\webapps\\SpringAOP\\springaop\\application-context.xml"); 
            
            Animal tomdog = (Animal)bean.getBean("tomdog"); 
            tomdog.walwal(); 
    } 
}
