spring mvc 使用@ResponseBody报错的解决方法

spring 3.0 mvc在从后台向前台返回时要转化成json串，但页面上报了

The resource identified by this request is only capable of generating responses with characteristics not acceptable according to the request "accept" headers

异常信息

org.springframework.web.HttpMediaTypeNotAcceptableException: Could not find acceptable representation

后台controllor

(= = RequestMethod.)
Map<StringObject> ((= = ) String custToken) {
    Map<StringObject> returnMap = HashMap<StringObject>() result = .queryYebAssets(custToken)returnMap.put(result)returnMap}

网上很多的说法是引入如下两个包

<dependency>

<groupId>org.codehaus.jackson</groupId>

<artifactId>jackson-core-asl</artifactId>

</dependency>

<dependency>

<groupId>org.codehaus.jackson</groupId>

<artifactId>jackson-mapper-asl</artifactId>

</dependency>

除此之外还要修改spring的配置文件里加入如下

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

本项目中引入了其他的json文件，并没有引入上述的两个包。配置文件中加上后也是可以正常转化的。
