Accelerating at 1g for half of the trip and then decelerating at 1g for the remainder would certainly be a way to produce artificial gravity.

However, current (and future) propulsion methods either have high thrust or high specific impulse. This means you can only have 1g acceleration for a short period or much lower acceleration for an extended period of time.

Ships that can achieve continuous 1g acceleration are called torchships in sci-fi but unfortunately there are no predicted methods to produce them yet.
