我开始使用 spring 框架 3.1.2 学习 AOP。但我有麻烦。在Beans.xml上下文文件中我写道：
<?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"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
http://www.springframework.org/schema/aop
http://www.springframework.org/schema/aop/spring-aop-3.0.xsd ">
<bean id = "audience" class="com.MySpring.Audience"></bean>
<aop:config>
<aop:aspect ref="audience">
<aop:pointcut id="performance" expression="execution(* com.MySpring.Performer.perform(..))"/>
<aop:before pointcut-ref="performance" method="seatDown"/>
<aop:before pointcut-ref="performance" method="turnOffPhone"/>
<aop:after-returning pointcut-ref="performance" method="applauz"/>
<aop:after-throwing pointcut-ref="performance" method="demandRefund"/>
</aop:aspect>
</aop:config>
</beans>
和Java类
public class AOPTest {
/**
* @param args
*/
public static void main(String[] args) {
// TODO Auto-generated method stub
ApplicationContext context = new ClassPathXmlApplicationContext(
"Beans.xml");
}
}
// ///
class Audience {
public void seatDown() {
out.println("Seat down");
}
public void turnOffPhone() {
out.println("Turn Off Phone");
}
public void applauz() {
out.println("Aplauz");
}
public void demandRefund() {
out.println("We have money back");
}
}
////
interface Performer{
void perform();
}
但在错误控制台中我看到：
Description Resource Path Location Type
Error occured processing XML 'class path resource [org/aopalliance/aop/Advice.class] cannot be opened because it does not exist'. See Error Log for more details Beans.xml /AnnotationsWiring/src line 11 Spring Beans Problem
第二个错误：
Description Resource Path Location Type
Error occured processing XML 'org/springframework/aop/aspectj/AspectJMethodBeforeAdvice'. See Error Log for more details Beans.xml /AOP/src line 12 Spring Beans Problem
