好久不搭架构，今天使用spring+springmvc整合mabytis的时候，坑爹的两个问题发生了。
花了一晚上解决这两个问题。现在将错误经验总结分享下，避免以后遇到坑继续往里跳。
1. 单元测试的时候,单元测试失败报错: A ServletContext is required to configure default servlet handling

执行单元测试的时候，报错了警告: Exception encountered during context initialization - cancelling refresh attempt
org.springframework.beans.factory.BeanCreationException: Error creating bean with name ‘defaultServletHandlerMapping' defined in class path resource [org/springframework/web/servlet/config/annotation/DelegatingWebMvcConfiguration.class]: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.springframework.web.servlet.HandlerMapping]: Factory method ‘defaultServletHandlerMapping' threw exception; nested exception is java.lang.IllegalArgumentException: A ServletContext is required to configure default servlet handling
这时候去检查spring-core和springMVC的两个配置文件，异常提示信息大意是ServletContext需要配置默认servlet处理映射器。一脸懵逼。。。最后发现是两个配置文件的context和包扫描配置有问题，springServlet上下文应该在spring核心配置中( spring_ynyn_dependence.xml )处理，需要使用 <context:annotation-config /> 进行配置。调整后的配置是：
1.sprin框架的配置文件spring_ynyn_dependence.xml调整
|

|
将以下配置内容<context:component-scan base-package="org.byron4j.ynyn.*" > <context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller" /> </context:component-scan>替换为：<context:annotation-config /> |
2.springMVC的配置文件spring-mvc.xml调整
|

3
|
<context:component-scan base-package="com.crfchina.mcp.*" > <context:include-filter type="annotation" expression="org.springframework.stereotype.Controller" /> </context:component-scan> |
再次执行单元测试，OK。
二. mapper注入失败使用@Autowired注解: 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)}

解决第一个问题，单元测试后，部署该项目启动时，疯狂报错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)}。多次检查，发现springMVC配置文件中也需要加载mybatis配置，前面我仅仅在spring上下文核心配置文件(spring_ynyn_dependence.xml)中做了配置。
在spring-mvc.xml文件最后引入加载mybatis配置：

1
|
<import resource="classpath*:byron4j_ynyn_datasource.xml"/> |
重新部署应用启动服务无措，发起请求验证OK。
