BeforeAdvice

IHello.java
package onlyfun.caterpillar;

public interface IHello {
    public void hello(String name);
}

HelloSpeaker.java
package onlyfun.caterpillar;

public class HelloSpeaker implements IHello {
    public void hello(String name) {
        System.out.println("Hello, " + name);
    }
}

LogBeforeAdvice.java
package onlyfun.caterpillar;

public class LogBeforeAdvice
        implements MethodBeforeAdvice {
    private Logger logger =             Logger.getLogger(this.getClass().getName());

    public void before(Method method, Object[] args, Object target) throws Throwable {
      //权限控制
   }
}

<beans>
    <bean id="logBeforeAdvice"
          class="onlyfun.caterpillar.LogBeforeAdvice"/>

    <bean id="helloSpeaker"
          class="onlyfun.caterpillar.HelloSpeaker"/>

    <bean id="helloProxy"
          class="org.springframework.aop.framework.ProxyFactoryBean">
        <property name="proxyInterfaces">
            <value>onlyfun.caterpillar.IHello</value>
        </property>
        <property name="target">
            <ref bean="helloSpeaker"/>
        </property>
        <property name="interceptorNames">
            <list>
                <value>logBeforeAdvice</value>
            </list>
        </property>
    </bean>
</beans>

package onlyfun.caterpillar;

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("Justin");
    }
}

package onlyfun.caterpillar;

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("Justin");
    }
