情况是这样。 我要为一个POST请求生成一个JSON，于是就有了下面这个Controller和这个JSP
@RequiresRoles("ROLE_USER")
@RequestMapping(value = "/ajax/cost-pie", method = RequestMethod.POST)
public String costPie(
ModelMap modelMap
)
{
Map<String, Double> map = myService.getData(); // 经调试，读取数据业务逻辑完全正常
modelMap.put("map", map);
return "statistics/ajax/cost-pie";
}
有了数据以后我借助WEB-INF/jsp/statistics/ajax/cost-pie.jsp来帮我生成JSON
没有借助FastJSON 或 Jackson

以下是我spring-mvc.xml配置
<bean id="contentNegotiationManager" class="org.springframework.web.accept.ContentNegotiationManagerFactoryBean">
<property name="favorPathExtension" value="true" />
<property name="favorParameter" value="true" />
<property name="parameterName" value="format" />
<property name="ignoreAcceptHeader" value="true" /> <!-- 忽略HttpHeader:Accept -->
<property name="mediaTypes">
<value>
json=application/json
xml=application/xml
html=text/html
</value>
</property>
<property name="defaultContentType" value="text/html" />
</bean>
<bean class="org.springframework.web.servlet.view.ContentNegotiatingViewResolver">
<property name="order" value="0" />
<property name="contentNegotiationManager" ref="contentNegotiationManager"/>
<property name="defaultViews">
<list>
<bean class="com.alibaba.fastjson.support.spring.FastJsonJsonView" />
</list>
</property>
</bean>
<bean id="defaultViewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="order" value="1" />
<property name="viewClass" value="org.springframework.web.servlet.view.JstlView" />
<property name="contentType" value="text/html" />
<property name="prefix" value="/WEB-INF/jsp/" />
<property name="suffix" value=".jsp" />
</bean>
奇怪的现象是，即使我配置了ignoreAcceptHeader=true，当请求http://localhost:8080/statistics/ajax/cost-pie
（FireBug调试可知 Header.Accept=application/json）到达后最后mvc框架最终用FastJsonJsonView帮我展示的数据，
而不是我期望的JstlView！！！
我是用的软件版本如下
spring/spring-mvc 3.2.4.RELEASE
fastjson 1.1.36
有哪位大神遇到过和我一样的问题吗？ 请多指教。
