java - 使用JavaBrains中的代码时发生异常

我正在JavaBrains的Koushik的帮助下学习Spring和AOP。我现在在这节课上：
http://javabrains.koushik.org/2011/08/spring-tutorial-27-writing-our-first.html
但是，当我尝试运行它时，出现以下异常：

Exception in thread "main" org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'triangle' defined in class path resource [spring.xml]: Initialization of bean failed; nested exception is java.lang.VerifyError: class net.sf.cglib.core.DebuggingClassWriter overrides final method visit.(IILjava/lang/String;Ljava/lang/String;Ljava/lang/String;[Ljava/lang/String;)V

以下是本教程中使用的类文件和xml文件：

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

}

package org.koushik.javabrains.service;

    }

我将不胜感激。
先感谢您。

最佳答案

解决了！问题是我在AspectJ库中有一个cjlib-2.2.2.jar，在JRE系统库中有一个cjlib-2.2.3.jar。当我删除第二个时，它开始像预期的那样工作。
