Spring AO问题
老是提示这样的错误
Exception in thread "main" org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'loggerBean' defined in class path resource [test/applicationContext.xml]: 
Initialization of bean failed; nested exception is org.springframework.aop.framework.AopConfigException: Couldn't generate CGLIB subclass of class [class test.LogBean]:
 Common causes of this problem include using a final class or a non-visible class; nested exception is net.sf.cglib.core.CodeGenerationException: java.lang.reflect.InvocationTargetException-->null

package test;

public class LogBean {
public Object aroundLogCalls(ProceedingJoinPoint joinPoint)throws Throwable{

System.out.println("before invoke method:"+joinPoint.getSignature().getName());

AOPBean文件
package test;

public class AOPBean {
public void display(){
System.out.println("AOPBean.display()");
}

}


AOPMain文件
package test;

import org.springframework.context.support.ClassPathXmlApplicationContext;

public class AOPMain {

/**
* @param args
*/
public static void main(String[] args) {
// TODO Auto-generated method stub
ClassPathXmlApplicationContext factory =
new ClassPathXmlApplicationContext("test/applicationContext.xml");

AOPBean aopbean = (AOPBean)factory.getBeanFactory().getBean("aopBean");
aopbean.display();
}

}






------解决方案--------------------------------------------------------

Java code
ClassPathXmlApplicationContext factory = new ClassPathXmlApplicationContext("test/applicationContext.xml");
------解决方案--------------------------------------------------------
Couldn't generate CGLIB 说明少包了
------解决方案--------------------------------------------------------
这是有关aop里面出的问题
他那个包有问题
