错误的Scheduler groupScheduler = Schedulers.newParallel("groupByPool", 16); Flux.fromStream(incomingMessages()) // stream of new data from socket .groupBy(Message::getEntityId) // split incoming messages by groups, which should be processed serially .map(g -> g.publishOn(groupScheduler)) //create new publisher for groups of messages .subscribe( //create consumer for main stream stream -> stream.subscribe(this::processMessage) // create consumer for group stream and process messagaes );密钥路径。你丢失了:cityname

:custcity

允许@custcity = Custcity.create({cityname: params[:customer][:custcity][:cityname], cust_id: @customer.id})：

cityname

将表单数据插入两个表，其中一个提交在rails中
