Johnson scored 11 goals in 33 appearances last season, including a hat-trick in the Cottagers' 6-0 thrashing of QPR.
The former Birmingham, Crystal Palace and Everton striker joined Fulham in 2008, playing 86 Premier League games and scoring 13 goals in total.
Johnson made eight appearances for England between 2005-07 but failed to get on the scoresheet.
