<aop:before pointcut-ref="somePointcut" method="before"/>
</aop:aspect>
</aop:config>
<bean id="aspectHello" class="tao.aspect.AspectHello"></bean>

<bean id="component" class="tao.aspect.service.impl.ComponentImpl"></bean>package tao.aspect.service;public interface Component {
public void business();
}
================================
package tao.aspect.service.impl;import tao.aspect.service.Component;public class ComponentImpl implements Component{

public void business(){
System.out.println("xxxxxxxxx");

package tao.aspect;
public class AspectHello { public void before() {
