SpringMVC 3.2.* json 406

今天项目请求json时报了这个诡异的且从来没有遇到到的错误：The resource identified by this request is only capable of generating responses with characteristics not acceptable according to the request "accept" headers.

解决办法：

1、将springmvc 文件的 xsd修改为3.2版本，如：

http://www.springframework.org/schema/mvc/spring-mvc-3.2.xsd

2、将<mvc:annotation-driven/> 修改为

<mvc:annotation-driven content-negotiation-manager="contentNegotiationManager"/>
    <bean id="contentNegotiationManager"
          class="org.springframework.web.accept.ContentNegotiationManagerFactoryBean">
        <property name="favorPathExtension" value="false" />
        <property name="favorParameter" value="true" />
        <property name="parameterName" value="mediaType" />
        <property name="ignoreAcceptHeader" value="true"/>
        <property name="useJaf" value="false"/>
        <property name="defaultContentType" value="application/json" />

        <property name="mediaTypes">
            <map>
                <entry key="json" value="application/json" />
                <entry key="xml" value="application/xml" />
            </map>
        </property>
    </bean>

这样问题得到解决了。。
