java.lang.IllegalStateException: Failed to load ApplicationContext解决办法

配置springMVC框架时总是出错，如下：

最后发现，我需要依赖注入controller、service两个bean，但是一开始我只是自动依赖注入了controller如：

<!-- 自动扫描 -->
	<context:component-scan base-package="com.rest.tiis.controller" />

修改成：

<!-- 自动扫描 -->
	<context:component-scan base-package="com.rest.tiis.controller" />
	<context:component-scan base-package="com.rest.tiis.service" />

以上为我个人的报名。
问题瞬间解决，两个小时，就这么。。。
一切总结起来就是：
我们只会用，不知道底层到底是怎么设计的，永远停留在应用的层面，很难提高coding效率！！多看书、多看源码、多交流！！！

其实你还是错的，两个扫描要放到不同的配置文件下。
“Spring MVC最打击新人的事情，你必须保证spring-mvc.xml的<context:component-scan>只扫描Controller，而 applicationContext.xml里的不包含Controller。”
看一下江南白衣的说明吧，https://github.com/springside/springside4/wiki/Spring-MVC。
或者在ITEYE上找张开涛的SpringMVC教程具体学习一下。

你说的很对，这个确实对新人来说是个挑战，继续研究中！
