I want to use boolean intersect, but after I did, it's uv is messed up.

Look at this picture, you can see 6 rounded cylinders with 1 cylinder has 6 vertices.
Now I apply boolean intersect. Result looks fine.
But when I unwrap the mesh, uv is totally messed up.
It's twisted and distorted. How to I fix this?
