Scala slick MySQL field too many tuple issues

The original synchronization service is normal, due to the need, the other Side single table new fields, more than 22

SBT Assembly Compilation Error

Too many elements for tuple:26, allowed:22

Scala case class supports a maximum of 22 construction parameters

And find a way out.

Final Application Slickless Solution

Some examples

ImportSlick.jdbc.H2Profile.api._ImportShapeless. {Hlist,::,Hnil,Generic}ImportSlickless._CaseClassUser (Id:Long,EmailString)ClassUsers (TagTAG)Extendstable[User] (tag,The Users") {DefId= column[Long] ( "id", O.PrimaryKey, o.AutoInc) def email = column[  String] ("email") def * = (ID :: Email :: hnil). Mappedwith (generic[  User])}lazy val users = tablequery[users]        

　

Conversion based on tupled required

    Case (byoffset_get,lastid:int) + = {println ("Sync Start by", LastID) val words = Tablequery[words]// Val Action=origin_db.run (Word.filter (_.id > LastID). Take (page_size).

Based on Hlists/generics, you do not

  Case (byoffset_get,lastid:int) + = {println ("table" +tablename+ "Sync Start by", LastID) val users = Tableq Uery[users]//Val Action=origin_db.run (User.filter (_.id > LastID). Take (page_size). Result) Val Action=or  Igin_db.run (Users.filter (_.id > LastID). Take (page_size). Result) Action.oncomplete (data=>{println ("table  "+tablename+" Sync get Data ", Data.get.length) if (data.issuccess) {val Users=data.get.tolist if (users.length>0) {future {println (S "Blocking table" +tablename+ "next page 1s start") timeunit.seco              Nds.sleep (1) println (S "Blocking table" +tablename+ "next page 1s finished")//sync only consider insert if (Is_just_insert) {self! ( Byoffset_insert,users)}else{//If historical data is updated self! (            byoffset_insert_update,users)}}}else{Future {  println (S "Blocking table" +tablename+ "future 5m Start") TimeUnit.MINUTES.sleep (5) println (S " Blocking table "+tablename+" 5m finished ") Self!          (Byoffset_get,lastid)} }}else{Future {println (S "Blocking table" +tablename+ "The Future 5m start") Ti MeUnit.MINUTES.sleep (5) println (S "Blocking table" +tablename+ "future 5m finished") Self!        (Byoffset_get,lastid)} }})}//Insert data case (Byoffset_insert,users:list[user]) =>{println ("table" +tablename+ "Insert Star T ", users.length) val user = Tablequery[users]//user.+= (user.unapply (users.head). Get) Val insertactions = D        Bio.seq (user++=users) dest_db.run (insertactions) OnComplete (data=>{if (data.issuccess) {   println ("table" +tablename+ "Insert data result", data)//Added after successful update last table Val lastid=users.last.id      Sync.lastactor!
