将JSON数组发送到Spring BootRestController

Question

我发了这样的帖子：

{
  "stuff": [
    {
      "thingId": 1,
      "thingNumber": "abc",
      "countryCode": "ZA"
    },
    {
      "thingId": 2,
      "thingNumber": "xyz",
      "countryCode": "US"
    }
  ]
}

我可以检索控制器中的数据，如下所示：

@RequestMapping(value = "/stuffs", method = RequestMethod.POST)
public String invoices(@RequestBody Map<String, List <Stuff>> stuffs) {

    return "Hooray";
}

@RequestMapping(value = "/stuffs", method = RequestMethod.POST)
public String invoices(@RequestBody List <Stuff> stuffs) {

    return "I'm sad that this won't work.";
}

    {
      [
        {
          "thingId": 1,
          "thingNumber": "abc",
          "countryCode": "ZA"
        },
        {
          "thingId": 2,
          "thingNumber": "xyz",
          "countryCode": "US"
        }
      ]
    }

我确信这很简单，但我无法从我的StackOverflow和Google搜索中提炼出答案。

任何帮助都将不胜感激！：）

请注意，如果您试图获得一个没有Java类的JSON数组（在OP的问题中，该类是“stuff”），则需要像下面这样设置Spring Boot控制器：

@RequestMapping(value = "/stuffs", method = RequestMethod.POST)
public String invoices(@RequestBody Map<String, Object> [] stuffs) {

    return "Hooray";
}
