well, that is vanilla. spawners re very fragile near tnt. if you still want to use tnt for whatever reason (for example the old blazebomber used to do this, the ex-best and still one of the 2 fastest moneyfarms on cubecraft), you can use water to block the explosion force either locally on the spawers, or you build a simple and small contraption which perfectly aligns your tnt blocks to the middle of a block once ignited, because this wy, if its submerged in a watersource, mobs still take explosion damage but blocks dont.
