spring aop 配置

Spring的AOP分为注解和配置两种方式实现. 网上注解的例子比较多.

看了视频, 写了个简单的以备后用.

Common.java 普通的类

package trytry.aop;
/**    
* @author 李晨        
* @version 创建时间：Jul 28, 2009 3:01:01 PM    
*/
public class Common {

  public void show(){
     System.out.println("------------------普通----------------");
   }
}

Check.java 验证的类

package trytry.aop;
/**    
* @author 李晨        
* @version 创建时间：Jul 28, 2009 3:03:08 PM    
*/
public class Check {

  public void show(){
     System.out.println("------------------验证----------------");
   }
}

下面是核心的Spring的配置文件applicationContext-aop.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: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-2.5.xsd
       http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-2.5.xsd
       http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-2.5.xsd">
    
  <bean id="common" class="trytry.aop.Common"/>
  <bean id="check" class="trytry.aop.Check"/>
    
  <aop:config>
    <aop:aspect id="deal" ref="check">
      <aop:pointcut id="target" expression="execution(* trytry.aop.Common.show(..))"/>
      <aop:before method="show" pointcut-ref="target"/>
    </aop:aspect>
  </aop:config>
    
</beans>

最后是主程序调用,测试测试

package trytry.aop;

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

/**    
* @author 李晨        
* @version 创建时间：Jul 28, 2009 3:06:07 PM    
*/
public class Client {

  public static void main(String[] args) {
     BeanFactory factory=new ClassPathXmlApplicationContext("applicationContext-aop.xml");
     Common c=(Common) factory.getBean("common");
     c.show();
   }

}

测试结果,在控制台打印

------------------验证----------------
------------------普通----------------

完
