Most airliners have the wing spars attached to a rigid wing spar box at the fuselage. It is just as strong as a carry-through spar, and leaves room in the fuselage for fuel/baggage/accessory systems. It also saves weight of what would be the biggest and heaviest part of the spar running through the center of the plane. With smaller planes it's not such a big factor and they often do have continuous spars.
One smooth landing is skill. Two in a row is luck. Three in a row and someone is lying.

If you are thinking of a big piece of metal running from one side to the other holding the wings together, then the answer is no.
As HAL has mentioned the wings are attached to a box, also known as a torque box. The box is tensioned by wing planks, plates that hold it together and the wings themselves are attached to the box usually by three or four bolts (big bolts mind).
