JSONObject的问题- 在用JSONObject传参到controller接收为空白和JSONArray添加json后转string不正确...

问题一：

在用JSONObject传参到controller接收为空白的问题：

@RestController
@RequestMapping("/callback")
public class CallbackApiController {
    Logger logger = (());

    @PostMapping("/callBackJson")
    public void callBackJSON(@RequestBody  jsonObject){
        ("传递参数，param={}",());
        ("-------->回调成功！<------------");
    }


}

运行结果：

2020-05-14 13:53:47.398 INFO 32904 --- [io-16016-exec-1] : 传递参数，param={}
2020-05-14 13:53:47.398 INFO 32904 --- [io-16016-exec-1] : -------->回调成功！<------------

将JSONObject的类型从



替换为
 
 
的运行成功，结果如下：
 
 
2020-05-14 13:56:09.585 INFO 33684 --- [io-16016-exec-2]  : 传递参数，param={"url":""}
2020-05-14 13:56:09.585 INFO 33684 --- [io-16016-exec-2]  : -------->回调成功！<------------
 
 
 
 
 
问题二
 
 
public static void main(String[] args) {
 JSONObject json = new JSONObject();
 JSONArray array = new JSONArray();
 ("mm","22");
 ("timestamp","jljlj");
 (json);
 ();
 ("mm","jjj");
 ("timestamp","oooo");
 (json);;
 (());
 }
运行结果[{"mm":"jjj","timestamp":"oooo"},{"$ref":"$[0]"}]
这样导致传送数据给第三方的接口时总是报错500解析不了，这是第二个加入的是第一个的引用，索引应该创建两个对象加入array中，如下正常
 public static void main(String[] args) {
 JSONObject json = new JSONObject();
 JSONObject json2 = new JSONObject();
 JSONArray array = new JSONArray();
 ("mm","22");
 ("timestamp","jljlj");
 ("mm","jjj");
 ("timestamp","oooo");
 (json);
 (json2);
 (());
 }
 运行结果：[{"mm":"22","timestamp":"jljlj"},{"mm":"jjj","timestamp":"oooo"}]
