springCloud发送请求多对象参数传递问题

今天做修改的时候遇到个很奇怪的问题，参数是两个对象，直接放到map中向消费者传递，方法用map接收，死活接收不到，问了下前辈说map中是多对象时接收容易出错，推荐我传递JSON,照他说的把问题解决了，代码发上来以后长个记性。

先看有问题的，请求：

public R updateChargeStandard(CaChargeStandardTemplate caChargeStandardTemplate){
        SysEmployeeInfo user = (SysEmployeeInfo) SecurityUtils.getSubject().getSession().getAttribute("user");
        Map<String,Object> params = new HashMap<>();
        params.put("user",user);
        params.put("caChargeStandardTemplate",caChargeStandardTemplate);
       return chargeStandardService.updateChargeStandard(params);
    }

接收：

  public R updateChargeStandard(@RequestBody Map<String,Object> params){
        CaChargeStandardTemplate caChargeStandardTemplate = (CaChargeStandardTemplate)params.get("caChargeStandardTemplate");
        SysEmployeeInfo user = (SysEmployeeInfo)params.get("user");
        int i = chargeStandardService.updateChargeStandard(caChargeStandardTemplate,user);
        return  i > 0 ? R.ok("保存成功"):R.error("保存失败");
    }

再看修改之后的

请求：

 public R updateChargeStandard(CaChargeStandardTemplate caChargeStandardTemplate){
        SysEmployeeInfo user = (SysEmployeeInfo) SecurityUtils.getSubject().getSession().getAttribute("user");
        Map<String,Object> params = new HashMap<>();
        String userStr = JSON.toJSONString(user); //对象转String再放进map中
        String caChargeStandardTemplateStr = JSON.toJSONString(caChargeStandardTemplate);
        params.put("user",userStr);
        params.put("caChargeStandardTemplate",caChargeStandardTemplateStr);
       return chargeStandardService.updateChargeStandard(params);
    }

接收：

public R updateChargeStandard(@RequestBody Map<String,Object> params){
        String caChargeStandardTemplateStr = (String) params.get("caChargeStandardTemplate");//从map中取String
        CaChargeStandardTemplate caChargeStandardTemplate = JSON.parseObject(caChargeStandardTemplateStr,CaChargeStandardTemplate.class);//String转对象
        String userStr = (String) params.get("user");//从map中取String
        SysEmployeeInfo user = JSON.parseObject(userStr,SysEmployeeInfo.class);//String转对象
        int i = chargeStandardService.updateChargeStandard(caChargeStandardTemplate,user);
        return  i > 0 ? R.ok("保存成功"):R.error("保存失败");
    }

end.
