使用spring mvc3 @ResponseBody有415个不支持的媒体类型为什么？ [英] use spring mvc3 @ResponseBody had 415 Unsupported Media Type why?

问题描述

spring 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 is：

   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);
                }
            });

web.xml是：

<display-name>jbpm</display-name>

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

我ajax提交来自但是firefox视图是415不支持的媒体类型

I ajax submit the from but firefox view is 415 Unsupported Media Type

lib有jackson-mapper-asl-1.5.6.jar jackson-core-asl-1.5.6.jar spring version is 3.03

lib had jackson-mapper-asl-1.5.6.jar jackson-core-asl-1.5.6.jar spring version is 3.03

为什么提交不成功？

推荐答案

尝试明确接受标题： 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 for Ajax请求将json和xml读取到屏幕上，您可以尝试使用它示例代码模型。

The mvc-showcase sample spring application has a message converters example which reads json and xml to the screen with JQuery for Ajax request, you can try and use that example to model your code.
