The success formed part of a clean sweep for China who took all five titles for the first time.
Denmark also achieved the feat in 1948.
The men's singles was a repeat of last year's Olympic final in Beijing where Lin swept to a 21-12 21-8 success.
It was tougher on Sunday but, apart from a brief spell in the first game when the top seed led 19-17, second seed Lin was generally in control.
He rattled off four points in a row to take the game and reeled off seven points in succession to clinch a ninth triumph over his big rival in 10 meetings.
Lin, making his sixth appearance in a row in the final, also won the title in 2004, 2006 and 2007.
"There were a couple of times in the first game when I was not quite handling it but I managed to keep my form and I think I played well," he said.
"I can stay focused a lot better these days and I think that makes me a better player."
A capacity crowd of around 4,500 at the National Indoor Arena warmed to a high-class contest.
"I lost my focus on a few points but I played a lot better than I did at the Olympics.
"Psychologically, Lin Dan is difficult for me to beat," said runner-up Wei.
The women's final produced an upset when unseeded Chinese Wang Yihan, world number 17, downed Danish defending champion and world number one Tine Rasmussen 21-19 21-23 21-11.
"I didn't have any pressure on me. I just played the game I know and enjoyed it," Wang said.
China's sweep was completed by the men's doubles pairing of Cai Yun and Fu Haifeng who beat South Korea's Han Sang-hoon and Hwang Ji-man 21-17 21-15.
Although China won all five titles at the world championships in Beijing in 1987 they had never previously done so at the All Englands.
