怎么筛选数据，数据是从接口调过来，我的后端怎么判断呢 比如前端传个tool_name_id=卡尺，

可以使用蒙古DB， 里面有查询API, 自己写比较繁琐

哈哈 你俩逗死我了，他说的蒙古DB是MongoDB

[liuyh1024]

把返回的string类型的串，转成json，从里面取值判断。

MongoDB, https://www.mongodb.com/what-is-mongodb 提供java接口， 另外也可以应用在分布式方面

蒙古还是廷厉害的， 只要不是蒙古大夫

如果是字符串处理，可以用第三方的json类库， 你可以去搜索 java json 查找

我把传过来的数据变成json数据了且与实体类映射了MessRet messRet = JSONObject.parseObject(forObject, (Type) MessRet.class);List<MsTool> data = messRet.getData().getData();这个list是我的集合类数据，后面怎么弄？
