利用spring與springmvc對mabytis進行整合時無法注入mapper怎么解決？很多新手對此不是很清楚，為了幫助大家解決這個難題，下面小編將為大家詳細講解，有這方面需求的人可以來學習下，希望你能有所收獲。
1. 單元測試的時候,單元測試失敗報錯: A ServletContext is required to configure default servlet handling

這時候去檢查spring-core和springMVC的兩個配置文件，異常提示信息大意是ServletContext需要配置默認servlet處理映射器。一臉懵逼。。。最后發現是兩個配置文件的context和包掃描配置有問題，springServlet上下文應該在spring核心配置中( spring_ynyn_dependence.xml )處理，需要使用 <context:annotation-config /> 進行配置。調整后的配置是：
1.sprin框架的配置文件spring_ynyn_dependence.xml調整
將以下配置內容
<context:component-scan base-package="org.byron4j.ynyn.*" >
<context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller" />
</context:component-scan>
替換為：
<context:annotation-config />2.springMVC的配置文件spring-mvc.xml調整
<context:component-scan base-package="com.crfchina.mcp.*" >
<context:include-filter type="annotation" expression="org.springframework.stereotype.Controller" />
</context:component-scan> 再次執行單元測試，OK。

... 33 more解決第一個問題，單元測試后，部署該項目啟動時，瘋狂報錯nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type [org.byron4j.mcp.mapper.TaskerMapper] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency. Dependency annotations: {@org.springframework.beans.factory.annotation.Autowired(required=true)}。多次檢查，發現springMVC配置文件中也需要加載mybatis配置，前面我僅僅在spring上下文核心配置文件(spring_ynyn_dependence.xml)中做了配置。
在spring-mvc.xml文件最后引入加載mybatis配置：
<import resource="classpath*:byron4j_ynyn_datasource.xml"/>
重新部署應用啟動服務無措，發起請求驗證OK。
