. 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
------------------普通----------------
