Use throwing-message events and wrap your paths that need to be cancelled when one of the reaches the end, in a subprocess. Each path thows a message-event when it ends, causing the boundary-event to catch it and cancel all other flows.

thanks for  frederikheremans's help,it's helpful.

but is there a api to cancel a path?

[frederikherema1]

There is no way to cancel a "single" path, you can only cancel (delete) a full process-instance, using runtimeService.deleteProcessInstance(..)
