springboot项目前端传list后端接收

前端代码:

   $.ajax({
        url: 'xxxxxx',
        method: 'POST',
        contentType: 'application/json;charset=utf-8',
        data: JSON.stringify(that.testList),
        success: function (res) {
            console.log(res);
        }
    });

后端代码:

    @PostMapping("/getAnswer")
    @ApiOperation(value = "获取结果", notes = "")
    public ResponseBean getAnswer(@RequestBody List<String> questionIds){
        ......
    }

以上。
