spring默认注入方式引起的异常

Failed to convert property value of type [$Proxy0] to required type [com.travis.service.impl.userServiceImpl] for property 'service'

spring默认的注入为接口注入方式。

1.spring 配置中遇到该问题，可以通过注入的方式解决，代码如下：

<tx:annotation-driven transaction-manager="myTxManager" proxy-target-class="true"/>

2.我们想用实现类进行注入，需要做两方面的工作：

1.导入CGLIB库，即cglib.jar包
2.在spring配置文件applicationContext.xml中进行一下配置：<aop:aspectj-autoproxy proxy-target-class="true"/> 或者 <aop:config proxy-target-class="true"
></aop:config>表示可以用类注入

实际上，上面几种配置解决方法，我一条也没成功..不知是我版本问题还是什么..

但是依据最上面对spring默认注入方式的解释，我发现是因为在我的action中定义service时，我按快捷键导入包导入的是实现类userServiceImpl而不是接口userService,更改之后可以正常启动tomcat。
