前台json与后台实体bean自动对应

一、前台请求

特别注意的是：

1 data : JSON.stringify(tkt),//将生成的对象转成字符串传递后台

2 contentType:"application/json;charset=utf-8",//申明请求的媒体类型为json

<script type="text/javascript">
    $(function(){
        $("#testid").on("click",function(){
            var tkt = {};
            tkt.refundOrderId = 111111;
            var dts = [];
            var each = {};
            each.passengerName='张三';
            each.ticketNo='999-12435625';
            each.cusRetPrice=30;
            each.cusRetRate=0.15;
            each.cusRefundPrice=600;
            each.cusTicketPrice=800;
            dts.push(each);
            var each1 = {};
            each1.passengerName='李四';
            each1.ticketNo='999-12435626';
            each1.cusRetPrice=30;
            each1.cusRetRate=0.15;
            each1.cusRefundPrice=600;
            each1.cusTicketPrice=800;
            dts.push(each1);
            tkt.ticketInfos = dts;
            $.ajax({
                type : "POST",
                url : "${contextPath }/refund/confirm/backfill.do",
                data : JSON.stringify(tkt),
                dataType: "json",
                contentType:"application/json;charset=utf-8",
                success: function(data){
                    console.log(data);
                   }
            });
        });
    })
</script>

 

二、后台接收

特别注意的是：

1 @RequestBody spring mvc自动转换json字符串为实体

@RequestMapping(value = "/backfill", method = {RequestMethod.POST })
@ResponseBody
public String backfill(@RequestBody ConfirmRefundInfo confirmRefundInfo){

　　//...

}

 

三、配置json转换器

特别注意的是：

1 配置<value>application/json;charset=UTF-8</value>

<bean id="mappingJacksonHttpMessageConverter" class="org.springframework.http.converter.json.MappingJacksonHttpMessageConverter">
        <property name="supportedMediaTypes">
            <list>
                <value>text/html;charset=UTF-8</value>
                <value>application/json;charset=UTF-8</value>
            </list>
        </property>
    </bean>
