一.什么是内容协商
<!--1、检查扩展名(如my.pdf);2、检查Parameter(如my?format=pdf);3、检查Accept Header--> <bean id= "contentNegotiationManager" class= "org.springframework.web.accept.ContentNegotiationManagerFactoryBean"> <!-- 扩展名至mimeType的映射,即 /user.json => application/json --> <property name= "favorPathExtension" value= "true" /> <!-- 用于开启 /userinfo/123?format=json 的支持 --> <property name= "favorParameter" value= "true" /> <property name= "parameterName" value= "format"/> <!-- 是否忽略Accept Header --> <property name= "ignoreAcceptHeader" value= "false"/> <!--扩展名到MIME的映射;favorPathExtension, favorParameter是true时起作用 --> <property name= "mediaTypes"> <value> json=application/json xml=application/xml html=text/html </value> </property> <!--<property name="mediaTypes">--> <!--<map>--> <!--<entry key="xml" value="application/xml"/>--> <!--<entry key="json" value="text/plain"/>--> <!--<entry key="xls" value="application/vnd.ms-excel"/>--> <!--</map>--> <!--</property>--> <!-- 默认的content type ,在没有扩展名和参数时即: "/user/1" 时的默认展现形式 --> <property name= "defaultContentType" value= "text/html" /> </bean>
视图定义:
<bean class="org.springframework.web.servlet.view.ContentNegotiatingViewResolver"> <property name="order" value="0"/> <property name="contentNegotiationManager" ref="contentNegotiationManager"/> <property name="viewResolvers"> <list> <!-- 这个类用于jsp视图解析 --> <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <property name="prefix" value="/WEB-INF/page/"/> <property name="suffix" value=".jsp"/> </bean> </list> </property> <property name="defaultViews"> <list> <bean class="org.springframework.web.servlet.view.json.MappingJackson2JsonView"> </bean> <!-- for application/xml --> <bean class="org.springframework.web.servlet.view.xml.MarshallingView"> <property name="marshaller"> <bean class="org.springframework.oxm.castor.CastorMarshaller"> <property name="validating" value="false"></property> </bean> </property> </bean> </list> </property> </bean>
在mvc:annotation-driven里面配置使用内容协商
<mvc:annotation-driven conversion-service= "conversionService" content-negotiation-manager= "contentNegotiationManager”/>
spring ContentNegotiationManagerFactoryBean 内容协商
