前台使用Vue post请求，后台如何接收请求参数

vue代码

      axios.post("DebugController/debugInterface",that.fileModal)
        .then(function(res) {
          that.button_isloading=false;
          that.isreadOnly=false;
          if (res.data.data!=null) 
          {
            that.headData = JSON.stringify(res.data.data.head);
            that.metaData = JSON.stringify(res.data.data.data);
          } 
          else 
          {
             that.$Notice.warning({
                  title: "查询出现异常,请检查",
                  desc: ''
                });
          }
          
        })
        .catch(function(err) {
          console.log(err)
        })

java代码
controller
方法一获得多个参数

@RequestMapping("debugInterface")
@ResponseBody
public ResultObj debugInterface(@RequestBody LinkedHashMap params) {
        ResultObj result = ResultObj.succeed();
        String serverName=params.get("serviceName");
        return result;
    }

方法二获得单个参数
方法三获得Bean
vue代码

axios.post('RedoController/updateRedoTask', redoCondition)
        .then(function(res) {
          that.addModifyModal = false
          that.$Notice.success({
            title: 'Redo任务修改成功。',
          });
          that.query()
        })
        .catch(function(err) {
          console.log(err)
        })

java代码

public void updateRedoTask(RedoConditionBean redoCondition) {
       RedoSvcTypeBean redoSvcType = redoCondition.getRedoSvcType();
       Date date=new Date();
       SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
       redoCondition.setModifyDate(sdf.format(date));
       redoConditionMapper.update(redoCondition);
       redoSvcTypeMapper.update(redoSvcType);
    }
