1.問題原因:SpringMvc驅動器沒有掃描該Controller層
雖然配置了
1 <!-- 啟用spring mvc 註解 --> 2 <context:annotation-config /> 3 4 <!-- 設定使用註解的類所在的jar包 --> 5 <context:component-scan base-package="cn.lonecloud.controller"></context:component-scan>
但是由於沒有啟用mvc驅動器導致其自動裝配失敗
解決辦法:
<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 /> <!-- 啟用spring mvc 註解 --> <context:annotation-config /> <!-- 設定使用註解的類所在的jar包 --> <context:component-scan base-package="cn.lonecloud.controller"></context:component-scan> </beans>
新增
<mvc:annotation-driven /> <mvc:default-servlet-handler />和mvc的schema檔案即可開啟驅動
