使用spring mvc3 @ResponseBody有415个Unsupported Media Type为什么？

Question

弹簧的xml：

<bean class="org.springframework.web.servlet.view.ContentNegotiatingViewResolver"> 
    <property name="mediaTypes"> 
     <map> 
      <entry key="atom" value="application/atom+xml" /> 
      <entry key="html" value="text/html" /> 
      <entry key="json" value="application/json" /> 
     </map> 
    </property> 
    <property name="viewResolvers"> 
     <list> 
      <bean class="org.springframework.web.servlet.view.BeanNameViewResolver" /> 
      <bean 
       class="org.springframework.web.servlet.view.InternalResourceViewResolver"> 
       <property name="prefix" value="/WEB-INF/views/" /> 
       <property name="suffix" value=".jsp" /> 
      </bean> 
     </list> 
    </property> 
    <property name="defaultViews"> 
     <list> 
      <bean 
       class="org.springframework.web.servlet.view.json.MappingJacksonJsonView" /> 
     </list> 
    </property> 
</bean> 

<bean id="viewResolver" 
    class="org.springframework.web.servlet.view.InternalResourceViewResolver"> 
    <property name="prefix" value="/WEB-INF/views/" /> 
    <property name="suffix" value=".jsp" /> 
</bean> 

<mvc:annotation-driven /> 

<context:annotation-config /> 

<context:component-scan base-package="org.lxh"></context:component-scan> 

和代码是：

@RequestMapping(value = "/2wt/test.do",method=RequestMethod.POST) 
public @ResponseBody 
Map<String, ? extends Object> create(
     @RequestBody WtStandartype wtStandartype) { 
    System.out.println(wtStandartype.getId() + "--------"); 
    return Collections.singletonMap("id", wtStandartype.getId()); 

} 

JavaScript是：

jQuery.ajax({ 
       'type': 'POST', 
       'url': '/2wt/test.do',//'WtStandardTypeList.do?addto=updb', 
       'contentType': 'application/json', 
       'data': JSON.stringify(jsonuserinfo), 
       'dataType': 'json', 
       'error':function(){ 
        alert(222); 
       }, 
       'success': function(){ 
        alert(33333); 
       } 
      }); 

的web.xml是：

<?xml version="1.0"?> 
    <web-app> 
<display-name>jbpm</display-name>

    <param-name>contextConfigLocation</param-name>

我从阿贾克斯但Firefox视图提交的是415不支持的媒体类型

LIB有杰克逊映射器-ASL-1.5.6.jar杰克逊核心ASL-1.5.6.jar春季版是3.03

为什么提交不成功？

试着把一个明确的Accept标题：application/json。

mvc-showcase示例Spring应用程序有一个消息转换器示例，它使用JQuery为Ajax请求读取json和xml到屏幕上，您可以尝试使用该示例为您的代码建模。
