SpringMvc自动装配@Controller无效

1.问题原因：SpringMvc驱动器没有扫描该Controller层

虽然配置了

     <!-- 启用spring mvc 注解 -->
     <context:annotation-config />
 
     <!-- 设置使用注解的类所在的jar包 -->
     <context:component-scan base-package="cn.lonecloud.controller"></context:component-scan>

但是由于没有启用mvc驱动器导致其自动装配失败

解决办法：

<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns:mvc="http://www.springframework.org/schema/mvc"
    xmlns:context="http://www.springframework.org/schema/context"
    xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd">
 
    <mvc:annotation-driven />
    <mvc:default-servlet-handler />
    <!-- 启用spring mvc 注解 -->
    <context:annotation-config />
 
    <!-- 设置使用注解的类所在的jar包 -->
    <context:component-scan base-package="cn.lonecloud.controller"></context:component-scan>
</beans>

添加

<mvc:annotation-driven />
    <mvc:default-servlet-handler />和mvc的schema文件即可开启驱动
