How do you set the right spawnpoint for new players?

Unzwar, I'm building a new Minecraft server 1.10.

And the problem is, if a player on the server who has never been on it, he spawns somewhere in the farm world. As main world is actually the spawn world indicated. Have tried with / setspawn, but so I can make a spawnpunkt in every single world.

Can someone help me that the new players in the spawn world spawn on the first time joins?

Can you fix it with a plugin, which teleports the player to certain coordinates at JoinEvent. https://dev.bukkit.org/...s/setspawn could also help if you do not program yourself
