Error creating bean with name 'userService' defined in file [D:\eclipse-jee-neon-3-win32-x86_64\jav

错误原因

Cannot proxy target class because CGLIB2 is not available. Add CGLIB to the class path or specify proxy interfaces.

Spring AOP底层自动的使用JDK的动态代理或者CGLIB代理

1：当对象有接口时，使用JDK动态代理

2：当对象没有接口时使用CGLIB代理

解决方案
（1）添加service层接口

（2）或导入cglib jar包

<dependency>

   <groupId>cglib</groupId>

   <artifactId>cglib</artifactId>

   <version>2.2.2</version>

   </dependency>

  </dependencies>
