No converter found for return value of type: class XXX.XXX....

阿新 • • 發佈：2021-10-08

目的：要將java物件直接返回成json串。。。

解決方法：

1. 可能是沒有新增處理json的依賴，需要新增jackson

2. 如果添加了依賴，

@RequestMapping("/getAllCities")
    @ResponseBody
    public ResponseResult getAllCities(){
        List<City> allCities = readerInfoService.getAllCities();
        ResponseResult responseResult = new ResponseResult(ResultCode.SUCCESS,allCities);

        
 
return responseResult;
    }

看你要返回的型別，我這裡即 ResponseResult類中是否缺少了 gettter 和 setter...

沒有的話需要新增。。。
