We prove Lipschitz continuity for localminimizers of integral functionals of the Calculus of Variationsin the vectorial case, where the energy density depends explicitlyon the space variables and has general growth with respect to thegradient. One of the models is $$ F\left(u\right)=\int_{\Omega}a(x)[h\left(|Du|\right)]^{p(x)}{\rm d}x $$
with h a convex function with general growth (also exponential behaviouris allowed).
