我无法弄清楚为什么我得到这个错误我的AspectJ Lib包括以下jar：

I can not figure out why am I getting this error my AspectJ Lib includes following jars:

• aspectjrt.jar


• aspectjweaver.jar


• cglib-2.2.2.jar


• aopalliance-1.0.jar


• asm-common-3.3.1.jar

• aspectjrt.jar
• aspectjweaver.jar
• cglib-2.2.2.jar
• aopalliance-1.0.jar
• asm-common-3.3.1.jar

这是我的主要方法：

package com.springaoppractice.aop;

import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

import com.springaoppractice.aop.service.ShapeService;

public class AopMain {

    public static void main (String[] args){

        ApplicationContext context = new ClassPathXmlApplicationContext("spring.xml");
        ShapeService shapeService = context.getBean("shapeService", ShapeService.class);
        System.out.println(shapeService.getCircle().getName());

    }
}

这是我的看点：

package com.springaoppractice.aop.aspect;

import org.aspectj.lang.annotation.Aspect;
import org.aspectj.lang.annotation.Before;

@Aspect
public class LoggingAspect {

    @Before("execution(public String getName())")
    public void LoggingAdvice (){
        System.out.println("Logging advice initiazlied, get method is called!");
    }
}

继承我的ServiceClass：

package com.springaoppractice.aop.service;

import com.springaoppractice.aop.model.Circle;
import com.springaoppractice.aop.model.Triangle;

public class ShapeService {

    private Circle circle;
    private Triangle triangle;

    public Circle getCircle() {
        return circle;
    }
    public void setCircle(Circle circle) {
        this.circle = circle;
    }
    public Triangle getTriangle() {
        return triangle;
    }
    public void setTriangle(Triangle triangle) {
        this.triangle = triangle;
    }
}

以下是我的模特：

package com.springaoppractice.aop.model;

public class Circle {

    private String name;

    public String getName(){
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }
}

package com.springaoppractice.aop.model;

public class Triangle {

    private String name;

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

}

这是我的SPRING .XML

添加到类路径的jar：

推荐答案

因为不正确的aopalliance jar，我遇到了同样的问题。
我之前使用的是aopalliance-alpha1.jar

So I was having the same issue due to incorrect aopalliance jar. What I had earlier was aopalliance-alpha1.jar

然后我将其更改为aopalliance-1.0.jar，您可以从 http://mvnrepository.com/artifact/aopalliance/aopalliance/1.0

But then I changed it to aopalliance-1.0.jar which you can download from http://mvnrepository.com/artifact/aopalliance/aopalliance/1.0

该计划正在为我工​​作。

The program is working for me.
