springMVC中使用Json数据相关配置

重点内容1，利用Jackson配置在springmvc的配置文件中

<bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter">
    <property name="messageConverters">
        <list >
            <ref bean="mappingJacksonHttpMessageConverter" />
        </list>
    </property>
</bean>
<bean id="mappingJacksonHttpMessageConverter" class="org.springframework.http.converter.json.MappingJacksonHttpMessageConverter">
    <property name="supportedMediaTypes">
        <list>
            <value>application/json;charset=UTF-8</value>
        </list>
    </property>
</bean>

方法2：利用FastJson

<mvc:annotation-driven>
     <mvc:message-converters register-defaults="true">
         <bean class="com.alibaba.fastjson.support.spring.FastJsonHttpMessageConverter">
             <property name="supportedMediaTypes" value="application/json"/>
         </bean>
     </mvc:message-converters>
</mvc:annotation-driven>

方法3：手动对所需接受和发送对象转换

方法1和方法2 通过使用springMVC的@Reponsebody、@RequestBody实现实体类与json的自动转换
