我读了很多关于这个问题的话题，但我还没有解决......也许我正在寻找太远的解决方案。我有以下课程：

我创建了一个要增强的界面：

public interface Performer {
    void peform();
}

impl类：

@Component
public class PianoShow implements Performer{
    public void peform() {
        System.out.println("this is a piano show, enjoy it !!!");
    }
}

aop类：

@Aspect
@Component
public class AspectJAudience {
    @Pointcut("execution(* org.test.spring.aop.Performer.peform(..))")
    public void performance() {

    }

    @Before("performance()")
    public void takeSeats() {
        System.out.println("The audience is taking their seats.");
    }

    @Before("performance()")
    public void turnOffCellPhones() {
        System.out.println("The audience is turning off their cellphones");
    }

    @AfterReturning("performance()")
    public void applaud() {
        System.out.println("CLAP CLAP CLAP CLAP CLAP");
    }

    @AfterThrowing("peformance()")
    public void demandRefund() {
        System.out.println("Boo! We want our money back!");
    }
}

正如一些话题所说，我已经更新了aop的jar依赖：

<properties>
           <spring.version>4.2.6.RELEASE</spring.version>
           <aspect.version>1.8.13</aspect.version>
</properties>
<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-aop</artifactId>
    <version>${spring.version}</version>
</dependency>
<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-aspects</artifactId>
    <version>${spring.version}</version>
</dependency>
<dependency>
    <groupId>org.aspectj</groupId>
    <artifactId>aspectjrt</artifactId>
    <version>${aspect.version}</version>
</dependency>
<dependency>
    <groupId>org.aspectj</groupId>
    <artifactId>aspectjweaver</artifactId>
    <version>${aspect.version}</version>
</dependency>
<dependency>
    <groupId>cglib</groupId>
    <artifactId>cglib</artifactId>
    <version>2.2.2</version>
</dependency>

并且spring配置文件是：

<?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:context="http://www.springframework.org/schema/context"
       xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd">

    <context:component-scan base-package="org.test.spring.aop"/>

    <aop:aspectj-autoproxy />
</beans>

关于这种话题有一些答案，解决方案只是更新aop的版本，我已按照他们的说法完成，但它不起作用，有什么帮助吗？谢谢！

ps：当我使用xml configure来执行aop时，它可以工作，但是当我使用注释方式时它不起作用

1 个答案:

答案 0 :(得分：1)

这是因为第二个AfterThrowing表达式中的拼写错误。我突出强调了代码需要纠正。

@AfterThrowing("peformance()")
public void demandRefund() {
    System.out.println("Boo! We want our money back!");
}

<强> @AfterThrowing（＆＃34; peformance（）＆＃34）

谢谢，
帕布
