It'll only use what it needs, so this is not bad.

where to set can use max can go to 32g.

It can go to 32, it just doesn't need to.

chage the gc not use cms use g1gc can slove it?

There's nothing to solve.

The JVM will use the entire heap only if it needs to. If it doesn't then why waste resources?
