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

Here is my main method:

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());

    }
}

Here is my Aspect:

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!");
    }
}

Heres my 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;
    }
}

Here are my model:

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;
    }

}

Here is my SPRING.XML

Jars that are added to classpath:

回答1:

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

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

The program is working for me.

回答2:

Had the same error. I downloaded aopalliance-1.0-sources.jar and aspectjweaver-1.7.1-sources.jar instead of aopalliance-1.0.jar and aspectjweaver-1.7.1.jar (without "source"). After downloading proper jars (@kriegaex links) it works well.

回答3:

Thanks for this question, I encounterd exactly the same error, its purely the Jar error. I resolved this issue by using asm-3.3.1.jar, aspectjrt.jar, cglib-3.1.jar, aopalliance-1.0.jar and aspectweaver-1.7.2.jar. I think its aopalliance and aspectweaver dependency which causes this error. Hope its helpful

回答4:

I had the same problem and im sure you are following java brains as i am :) just change the aopalliance -jar to aopalliance1.0-jar it works for me.

回答5:

For me it works nicely with this on the classpath (I did not use Maven on purpose and manually added all libs in Eclipe in order to replicate your setup):

The aspect's output appears on the console as expected. Maybe you want to compare your libs to mine. I strongly recommend to use Maven as a build tool though. This way you have more control over your dependencies.

Edit: I forgot to mention that my Eclipse project is an AspectJ project, not a normal Java project. I.e. I use ajc as a compiler, not javac. The result is compile-time weaving. If you want to use load-time weaving, please tell me and I will test it that way.

Edit 2: I have just converted my project to a normal Java project, i.e. javac compiles all classes/aspects and Spring AOP with LTW are now used to apply aspects. It still works flawlessly. My current library setup looks like this:
