使用@Resource注入，启动tomcat时抛出异常(解决办法在异常信息下面)：

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'adminController': Injection of resource dependencies failed; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type [com.guilinzhicheng.mapper.FindClassMapper] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency.

解决方法:在web.xml中需配置：

<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>

ContextLoaderListener：在web容器启动时，自动装配ApplicationContext的配置信息
