@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

1、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

1  @ApiOperation(value = "添加订单", notes = "添加订单", httpMethod = "POST") 2     @RequestMapping("/addOrder") 3     public BaseResource addOrder(@RequestBody BaseSingleList baseSingleList) { 4         log.info("controller传入数据:" + gson.toJson(baseSingleList)); 5 
6         return orderService.addOrder(baseSingleList); 7 
8 }

View Code

    传入对象的json格式

 1 {  2     "singleOrderList": [  3  {  4             "orderName": "wyy",  5             "orderPhone": "186683812781",  6             "contact": "wyy",  7             "telephony": "187738122781",  8             "provinceId": 123,  9             "cityId": 1-302, 10             "regionId": 19930203, 11             "address": "33363", 12             "userId": "32689d13465242dfad62ee1cdbf34d887", 13             "serieId": "94", 14             "trueTime": "2018-12-02", 15             "overTime": "2019-12-01", 16             "monthlyRent": 5000, 17             "dateCount": 18, 18             "packageId": "34ea0a3fb9a4496bab90488727ad6c57a09b", 19             "total": "3000000", 20             "ModularIdNum": [ 21  { 22                     "itemId": "b20f1c33256ae64ad576bec51e85d821eae1", 23                     "modularNum": 1
24  } 25  ], 26             "isRentAndSell": 11110, 27             "applicationArea": null, 28             "remark": null, 29             "instruPurpose": null
30  } 31  ] 32 }

2、传入后老是接收不到
      

"ModularIdNum": [
{
"itemId": "b20f1c33256ae64ad576bec51e85d821eae1",
"modularNum": 1
}
]
这段数组的值，原本觉得是@RequestBody没法解析问题，最后发现是字段的大小写问题

ModularIdNum 创建在实体类中，是不能大写的，须要小写modularIdNum

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

实体类对应
