@RequestBody jackson解析复杂的传入值的一个坑;jackson解析迭代数组;jackson多重数组;jakson数组

一、实际开发的一个问题。

传入一个json数组，数组中还嵌套数组，运用springboot+Jpa框架，@RequestBody注解传入数据

Controller

  @ApiOperation(value = "添加订单", notes = "添加订单", httpMethod = "POST")
     @RequestMapping("/addOrder")
     public BaseResource addOrder(@RequestBody BaseSingleList baseSingleList) {
         log.info("controller传入数据:" + gson.toJson(baseSingleList));

         return orderService.addOrder(baseSingleList);

 }

传入对象的json格式

 {
     "singleOrderList": [
         {
             "orderName": "wyy",
             "orderPhone": "186683812781",
             "contact": "wyy",
             "telephony": "187738122781",
             "provinceId": 123,
             "cityId": 1-302,
             "regionId": 19930203,
             "address": "33363",
             "userId": "32689d13465242dfad62ee1cdbf34d887",
             "serieId": "94",
             "trueTime": "2018-12-02",
             "overTime": "2019-12-01",
             "monthlyRent": 5000,
             "dateCount": 18,
             "packageId": "34ea0a3fb9a4496bab90488727ad6c57a09b",
             "total": "3000000",
             "ModularIdNum": [
                 {
                     "itemId": "b20f1c33256ae64ad576bec51e85d821eae1",
                     "modularNum": 1
                 }
             ],
             "isRentAndSell": 11110,
             "applicationArea": null,
             "remark": null,
             "instruPurpose": null
         }
     ]
 }

二、传入后总是接收不到

"ModularIdNum": [
{
"itemId": "b20f1c33256ae64ad576bec51e85d821eae1",
"modularNum": 1
}
]
这段数组的值，本来以为是@RequestBody无法解析问题，最后发现是字段的大小写问题

ModularIdNum 建立在实体类中，是不能大写的，需要小写modularIdNum

"modularIdNum": [
{
"itemId": "b20f1c33256ae64ad576bec51e85d821eae1",
"modularNum": 1
}
]

实体类对应
