解决方法：

在maven2的配置文件中，初始化下载的一些jar包中，加入cglib2.2 jar包的下载

Xml代码  

1. <dependency>  
2.     <groupId>cglib</groupId>  
3.     <artifactId>cglib</artifactId>  
4.     <version>2.2</version>  
5. </dependency>  

<dependency>
	<groupId>cglib</groupId>
	<artifactId>cglib</artifactId>
	<version>2.2</version>
</dependency>

 

 

再次启动时，debug报错消失

 

在resin服务器的lib下发现，当配置 上面的xml时候，会有包 cglib-2.2.jar 加载过来

可见，以上的错误信息是由于缺少这个包造成的，在相应的 lib中加入该包，就不会有这个问题了。

 

随文附上该包下载
