World champion in 2009, Ennis-Hill capped a memorable two days by storming home to win the final 800 metres heat in 2min 10.13sec to finish as the runaway winner with a total of 6,669 points at the Bird's Nest stadium, a season's best.
Canada's Commonwealth Games winner Brianne Theisen-Eaton, the gold medal favourite coming into the competition, settled for silver with 6,554 while Latvian Laura Ikauniece-Admidina claimed bronze with a national record 6,516.
A disconsolate Johnson-Thompson finished 28th and last on 5,039 points with eight competitors having previously dropped out.
The 22-year-old came unstuck after unwisely deciding to go for broke in the long jump, attacking the board aggressively in a bid to claw back some of Ennis-Hill's overnight advantage in the sweltering conditions.
But her high-risk strategy backfired as she fouled her first two attempts and was red-flagged again despite landing a huge third jump, leaving her devastated and prompting an official protest from British officials which was quickly withdrawn.
Ennis-Hill, who nailed a season's best long jump of 6.43m, gave her young rival a comforting hug after watching her suddenly crash out of medal contention from second overall.
A javelin throw of 42.51m then put Ennis-Hill on the brink before she wrapped up the formalities with a rousing finish, overtaking Theisen-Eaton on the back straight.
