JSONObject始终返回"empty":false [英] JSONObject always returns "empty": false

问题描述

有一个Spring Rest控制器:

There is a Spring Rest Controller :

@RestController
@RequestMapping("secanalytique")
public class SectionAnalytiqueController {

    @GetMapping(value = "/sectionbyaxepro/{codecomp}", produces = "application/json")
    public JSONObject getByAxePro(@PathVariable String codecomp) {
        JSONObject jsonModel = new JSONObject();
        jsonModel.put("cce0","frityyy");
        return jsonModel;
    }

}

我对邮递员进行了测试: http://172.20.40.4:8080/Oxalys_WS /secanalytique/sectionbyaxepro/8 ；而我得到的总是

I made a test with Postman : http://172.20.40.4:8080/Oxalys_WS/secanalytique/sectionbyaxepro/8 ; and what I got is always

{
    "empty": false
}

那怎么了?

推荐答案

我遇到了同样的问题，并找到了解决方法.

I met same issue, and found the way to handle.

@GetMapping(value = "/test/{id}", produces = MediaType.APPLICATION_JSON_VALUE)
public ResponseEntity<Object> getById(@PathVariable String id) {
    JSONObject jsObj = new JSONObject();
    jsObj.put("t0","test0");
    JSONArray jsArr = new JSONArray();
    jsArr.put(jsObj.toMap());

    return new ResponseEntity<>(jsObj.toMap(), HttpStatus.OK);
    //return new ResponseEntity<>(jsArr.toList(), HttpStatus.OK);
}
