Spring MVC <mvc: annotation-driven>, springmvc tutorial
Study <mvc: annotation-driven> In SpringMvc 3.2. If no other parameter is configured, It is roughly equivalent to the following configuration file (refer to from org. springframework. web. servlet. config. annotationDrivenBeanDefinitionParser)

<! -- Configure the media type mapped to the path extension --> <bean name = "pathExtensionContentNegotiationStrategy" class = "org. springframework. web. accept. pathExtensionContentNegotiationStrategy "> <constructor-arg> <props> <! -- If romePresent --> <prop key = "atom"> application/atom + xml </prop> <prop key = "rss"> application/rss + xml </prop> <! -- Endif --> <! -- If jackson2Present | jacksonPresent --> <prop key = "json"> application/json </prop> <! -- Endif --> <! -- If jaxb2Present --> <prop key = "xml"> application/xml </prop> <! -- Endif --> </props> </constructor-arg> </bean> <! -- Configure the ing media type policy --> <bean name = "mvcContentNegotiationManager" class = "org. springframework. web. accept. contentNegotiationManager "> <constructor-arg> <list> <ref bean =" pathExtensionContentNegotiationStrategy "/> </list> </constructor-arg> </bean> <! -- Configure the @ RequestMapping processor at the method level --> <bean name = "requestMappingHandlerMapping" class = "org. springframework. web. servlet. mvc. method. annotation. requestMappingHandlerMapping "> <property name =" order "value =" 0 "/> <property name =" contentNegotiationManager "ref =" mvcContentNegotiationManager "/> </bean> <! -- Configure the data conversion service.

When spring mvc is added to <mvc: annotation-driven/>, an error is reported when the project is started.

<! -- Start the annotation function of Spring MVC to map requests to annotation POJO -->
<Bean class = "org. springframework. web. servlet. mvc. annotation. AnnotationMethodHandlerAdapter">
<Property name = "messageConverters">
<List>
<Bean class = "org. springframework. http. converter. StringHttpMessageConverter">
<Property name = "supportedMediaTypes">
<List>
<Value> text/html; charset = UTF-8 </value>
</List>
</Property>
</Bean>
</List>
</Property>
</Bean>
The configuration is incorrect.

Use the <mvc: annotation-driven/> annotation in Spring to report an error in the test class.

<Mvc: annotation-driven/> indicates the injection of spring mvc components into the container. In this case, the container must use the webApplicationContext sub-container of applicationContext.
Therefore, we recommend that you modify the code ApplicationContext ac = new ClassPa... as follows:
ApplicationContext ac = new FileSystemXmlApplicationContext ("..."); // Replace the ellipsis with the configuration path.
Ac. getBean ("beanId ");
