java.lang.ClassCastException: com.sun.proxy.$Proxy8 cannot be cast to com.bjsxt.service.UserServiceImpl01_AOP.

对于Spring AOP 采用两种代理方法，一种是常规JDK，一种是CGLIB，我的UserDao了一个接口IUserDao，当代理对象实现了至少一个接口时，默认使用 JDK动态创建代理对象，当代理对象没有实现任何接口时，就会使用CGLIB方法。点此查看详细介绍>>>
治疗方法
如果你的代理对象没有实现接口的方法，就将代理对象转换成接口。
获取代理类的代码该为：

vate ApplicationContext ac = new ClassPathXmlApplicationContext("beans.xml");
IUserService iuserService=(IUserService)ac.getBean("userService");

或者在applicationcontext.xml里加上这一句

<aop:aspectj-autoproxy proxy-target-class="true"/>

临床表现: 使用Spring AOP动态代理: 使用Spring管理的bean类继承自某个接口: Spring容器中有你要代理的bean的id,但是该id不能强制转换成Bean类. 病例: 定义代理类: @Transactional @Repository public UserDaoImpl implements UserDao extends BaseDaoImpl{ /*没有实现任何接口*/ } 获取代理类: ApplicationContext ctx = new ClassPathXm

报这个错,只有一个原因,就是转化的类型不对. 接口过父类的子类,在强制转换的时候,一定要用接口父类来定义. 代码示例: package com.luoluo.dao.impl; import java.sql.Connection; import java.sql.SQLException; import javax.annotation.Resource; import javax.sql.DataSource; import com.luoluo.dao.UserDAO; import co
