参考文章：https://www.cnblogs.com/gxz-sw/p/6860447.html?ivk_sa=1024320u

1.先得有这个alibaba的jar包

<dependency>
    <groupId>com.alibaba</groupId>
    <artifactId>fastjson</artifactId>
    <version>1.2.66</version>
</dependency>

2.springmvc配置

<mvc:annotation-driven>
        <mvc:message-converters register-defaults="true">
            <!-- 避免IE执行AJAX时,返回JSON出现下载文件 -->
            <bean id="fastJsonHttpMessageConverter" class="com.alibaba.fastjson.support.spring.FastJsonHttpMessageConverter">
                <property name="supportedMediaTypes">
                    <list>
                        <value>application/json;charset=UTF-8</value>
                    </list>
                </property>
            </bean>
        </mvc:message-converters>
    </mvc:annotation-driven>

3.正常使用

 @ResponseBody
    @RequestMapping("/addFaceData")
    public Result addFaceData(Customer a, String baseimg){
