将区域数据批量导入到mongodb

val count = MongoClient.ins.query(com.xiaoxi.server.region.dao.Region::class) {}.count()
            //如果表中已经有数据了则不导入数据
            if (count > 0) return
            val regionInfo = MainServer.vertx.fileSystem().readFileBlocking(regionInfoPath).toString()
            val regionObject = JsonObject(regionInfo)
            MongoClient.ins.batchInsert(com.xiaoxi.server.region.dao.Region::class) {
                for (regionItem in Region.all) {
                    val regionFileObj = regionObject.getJsonObject(regionItem.code)
                    if (regionFileObj != null) {
                        add(com.xiaoxi.server.region.dao.Region().apply {
                            Code = regionItem.code
                            Code3 = regionItem.code3
                            Name = regionFileObj.getString("name")
                            Header = regionFileObj.getString("region")
                            Payload = regionFileObj.getJsonObject("payload")
                            CreateTime = timestamp()
                        })
                    } else {
                        add(com.xiaoxi.server.region.dao.Region().apply {
                            Code = regionItem.code
                            Code3 = regionItem.code3
                            Name = regionItem.name
                            Header = regionItem.header
                            CreateTime = timestamp()
                        })
                    }
                }
            }.exec()

分组查询，返回map<String!,JsonArray!>

//按照区域分组，获取对应的appId
            val appInfos = MongoClient.ins.aggregate(App::class) {
                match {
                    where(App::Status eq AppStatus.Enable.value)
                    where(or(App::UpdateTime lte timestamp().minus(10), App::UpdateTime eq null))
                }
                group {
                    id(App::Region)
                    pushByField("apps", App::AppID)
                }
            }.exec().associateBy({ it.getString("_id") }, { it.getJsonArray("apps") })
