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]:

ClassPathXmlApplicationContext factory = 
new ClassPathXmlApplicationContext("test/applicationContext.xml"); 

test/applicationContext.xml这个路径是对的吗?

你有src目录吗?如果有就改成src/applicationContext.xml要是还是不行.
就把全路径写上去试一试

Couldn't generate CGLIB 说明少包了

这是有关aop里面出的问题
他那个包有问题
