1.业务类
package cn.blogjava.aop;
public class HelloSpeaker implements IHello {
public void hello(String name) {
System.out.println("Hello, " + name );
}
}
2.将要添加Aspect的方法抽象到接口中
package cn.blogjava.aop;
public interface IHello {
public void hello(String name);
}
3.实现MethodBeforeAdvice接口，实现log功能
package cn.blogjava.aop;
import java.lang.reflect.Method;
import java.util.logging.Level;
import java.util.logging.Logger;
import org.springframework.aop.MethodBeforeAdvice;
public class LogBeforeAdvice implements MethodBeforeAdvice{
private Logger logger = Logger.getLogger(this.getClass().getName());
public void before(Method method, Object[] args, Object targer){
logger.log(Level.INFO, "method starts
" + method);
}
}
4.配置文件
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE beans PUBLIC "-//SPRING/DTD BEAN/EN"
"http://www.springframework.org/dtd/spring-beans.dtd">
<beans>
<bean id="logBeforeAdvice"
class="cn.blogjava.aop.LogBeforeAdvice"/>
<bean id="helloSpeaker"
class="cn.blogjava.aop.HelloSpeaker" />
<bean id="helloProxy"
class="org.springframework.aop.framework.ProxyFactoryBean">
<property name="proxyInterfaces">
<value>cn.blogjava.aop.IHello</value>
</property>
<property name="target">
<ref bean="helloSpeaker" />
</property>
<property name="interceptorNames">
<list>
<value>logBeforeAdvice</value>
</list>
</property>
</bean>
</beans>
5.测试类
package cn.blogjava.aop;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.FileSystemXmlApplicationContext;
public class SpringAopDemo {
public static void main(String[] args) {
ApplicationContext context =
new FileSystemXmlApplicationContext("beans-config.xml");
IHello helloProxy =(IHello)context.getBean("helloProxy");
helloProxy.hello("YYY");
}
}
