spring中用annotation版配置一个简单的aop总是报一下错

Exception in thread "main" org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'userDao' defined in file [F:\MyEclipse10WorkSpace\spring_01\bin\com\lsf\dao\impl\UserDao4MySqlImpl.class]: Initialization of bean failed; nested exception is java.lang.IllegalArgumentException: error at ::0 can't find referenced pointcut allAddMethod

Caused by: java.lang.IllegalArgumentException: error at ::0 can't find referenced pointcut allAddMethod

源代码如下：

@Component("userDao")
public class UserDao4MySqlImpl implements UserDao {

	@Override
	public void saveUser(User user) {
		System.out.println("------mysql-----");
	}


}

[shengfenglai]

@Service("userService")
public class UserServiceImpl implements UserService {
	private UserDao userdao;
	
	@Resource(name="userDao")
	public void setUserdao(UserDao userdao) {
		this.userdao = userdao;
	}
	/*构造方法注入依赖关系
	public UserServiceImpl(UserDao userdao) {
		this.userdao = userdao;
	}*/
	@Override
	public void addUser(User user) {
		userdao.saveUser(user);

	}
}
