启动程序后CGLIB错误（签名者信息与同一软件包中其他类的签名者信息不匹配）

Question

I am getting a CGLIB error while trying to run a program. I searched for the same issue, and found some threats, but without any solution.

Stack trace:

A spring.xml file look like:

<?xml version="1.0" encoding="UTF-8"?>

    <bean name="loggingAspect" class="org.max.tutorial.aspect.LoggingAspect"></bean>

</beans>

A Circle.java class is:

package org.max.tutorial.model;

public class Circle {

    private String name;

    public Circle() {
        // Empty
    }

    public Circle(String name) {
        this.name = name;
    }

    public String getName() {
        return name;
    }

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

}

I have imported all last stable Spring jars, AspectJ jars and aopalliance jar. Any suggestions? Thanks.


UPDATE:

LoggingAspect.java is

package org.max.tutorial.aspect;

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


@Aspect
public class LoggingAspect {

    @Before("execution(public String getName())")
    public void loggingAdvise() {
        System.out.println("Advice is run. Get method called.");
    }

}

And ShapeService.java is

package org.max.tutorial.service;

import org.max.tutorial.model.Circle;
import org.max.tutorial.model.Triangle;

public class ShapeService {

    private Triangle triangle;
    private Circle circle;

    public ShapeService() {
        // Empty
    }

    public ShapeService(Triangle triangle, Circle circle) {
        this.triangle = triangle;
        this.circle = circle;
    }

    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;
    }

}

The problem is resolved, I think it was a library conflict in eclipse.

After I converted a project to maven and build it with dependencies I need, the problem disappears.
