如何添加XML的JSON支持已经工作？

    <beans:bean class="org.springframework.web.servlet.view.BeanNameViewResolver"/>

    <!-- InternalResourceViewResolver should be the last sice it always returns/resolves a view -->
    <beans:bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <beans:property name="viewClass"  value="org.springframework.web.servlet.view.JstlView"></beans:property>

</beans:beans>

附加解决方案,用于：
    method = RequestMethod.POST,headers =“content-type = application / json”
你还需要：

<beans:bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter>
    <beans:property name="messageConverters">
        <beans:list>
            <beans:bean class="org.springframework.http.converter.json.MappingJacksonHttpMessageConverter" />
        </beans:list>
    </beans:property>
</beans:bean>

正确绑定@RequestBody的java对象.

<bean class="org.springframework.http.converter.json.MappingJacksonHttpMessageConverter">
       <property name="objectMapper">
            <ref bean="JacksonObjectMapper" />
       </property>
</bean>

<bean class="org.springframework.web.servlet.view.json.MappingJacksonJsonView">
    <property name="objectMapper">
         <ref bean="JacksonObjectMapper" />
    </property>
</bean>

<bean id="JacksonObjectMapper" class="org.codehaus.jackson.map.ObjectMapper" />

使用JaxB marshaller来实例化Jackson(我不认为)是没有意义的.

使用ContentNegotiatingViewResolver的示例：

<bean
    class="org.springframework.web.servlet.view.ContentNegotiatingViewResolver">
    <property name="mediaTypes">
        <map>
            <entry key="json" value="application/json" />
            <entry key="xml" value="application/xml" />
        </map>
    </property>
    <property name="defaultViews">
        <list>
            <bean
                class="org.springframework.web.servlet.view.json.MappingJacksonJsonView">
                <property name="objectMapper">
                    <ref bean="JacksonObjectMapper" />
                </property>
            </bean>
            <bean class="org.springframework.web.servlet.view.xml.MarshallingView">
                <property name="marshaller">
                    <ref bean="Jaxb2Marshaller" />
                </property>
            </bean>
        </list>
    </property>
    <property name="favorPathExtension" value="false" />
    <property name="favorParameter" value="true" />
    <property name="useNotAcceptableStatusCode" value="true" />
</bean>
