spring 整合Mybatis 错误:Error creating bean with name 'loginController': Injection of autowired dependencies failed......xxxxx

Error creating bean with name 'loginController': Injection of autowired dependencies failed......xxxxx

　　运行环境：jdk1.7.0_17+tomcat 7 + spring：3.2.0 +mybatis：3.2.7+ eclipse

　　错误：在使用框架时候启动报错：Error creating bean with name 'loginController': Injection of autowired dependencies failed......xxxxx

　　错误原因：在使用springmvc 注解开发中从错误来看提示我有一个bean 无法注入到容器，反复查看着了些资料是我没有告诉系统我的service是那个没有添加注解倒置的，特此写下原因记录下

　　解决办法：可以看到我下面接口实现service类并没有任何注解，只需要加上注解就ok了  "@Service" 告诉系统這是我的service

　　　　

　　错误代码：
