在Spring AOP中,必须将cglib库包含到构建路径中,以避免出现“ 由于CGLIB2不可用而无法代理目标类 ”的错误消息。
Exception in thread "main" org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'customerServiceProxy': FactoryBean threw exception on object creation; nested exception is org.springframework.aop.framework.AopConfigException: Cannot proxy target class because CGLIB2 is not available.

您可以从…下载cglib库。
1. Cglib官方网站
http://cglib.sourceforge.net/
2. Maven资料库
http://repo1.maven.org/maven2/cglib/cglib/2.2/
如果使用的是Maven,则可以仅包含Maven依赖项。
<!-- AOP dependency -->
<dependency>
<groupId>cglib</groupId>
<artifactId>cglib</artifactId>
<version>2.2</version>
</dependency>
