不论是性能、易用性、特性支持，fastjson都要远好于默认的jackson，所以如果应用程序经常使用ajax进行数据交互，建议用fastjson作为默认解析器，只需要简单配置：

<
mvc:annotation-driven
>
<
mvc:message-converters
register-defaults
=
"true"
>
<
bean
class
=
"com.alibaba.fastjson.support.spring.FastJsonHttpMessageConverter"
>
<
property
name
=
"supportedMediaTypes"
value
=
"application/json"
/>
<!--设置fastjson特性-->
<
property
name
=
"features"
>
<
array
>
<!--设置null值也要输出，fastjson默认是关闭的-->
<
value
>WriteMapNullValue</
value
>
<!--设置使用文本方式输出日期，fastjson默认是long-->
<
value
>WriteDateUseDateFormat</
value
>
</
array
>
</
property
>
</
bean
>
</
mvc:message-converters
>
</
mvc:annotation-driven
>
|
然后引入fastjson的包就好了。
附Spring MVC4示例配置文件：
