spring mvc 與fastjson集合

在使用spring mvc框架時候,有時候請求須要返回json格式.spring默認使用jackjson,可是我須要用fastjson,每次手動轉換比較麻煩,須要spring自動爲我轉換,配置代碼以下

Spring版本4.0.0

默認使用jackjson的配置
<annotation-driven>
</annotation-driven> 

使用fastjson的配置
    <annotation-driven>
      <message-converters register-defaults="true">
          <beans:bean id="fastJsonHttpMessageConverter" 
class="com.alibaba.fastjson.support.spring.FastJsonHttpMessageConverter">
                <beans:property name="supportedMediaTypes">
                    <beans:list>
                        <beans:value>application/json</beans:value>
                    </beans:list>
                </beans:property>
            </beans:bean>
        </message-converters>
    </annotation-driven>
