I have a motoman GP8 with YRC1000micro controller,which can receive right position message like "position: [0.08648243546485901, -0.033493515104055405, 0.3939070999622345, -0.09030033648014069, -0.3075391948223114, -1.54208505153656]",but when I change the demo.launch as someone said <arg name="fake_execution" value="false"/>,it didn't work，I want to know how to control GP8 by RViz

I had finished this erro by coping other demo

First, again: could you please use code blocks when copy-pasting terminal text?

I don't believe you can use demo.launch for interaction with a real robot, so I'm confused as to what you are trying to do.

This also seems like a MoveIt configuration problem, which would be better asked over at the MoveIt issue tracker.

Unable to identify any set of controllers that can actuate the specified joints: [ joint_b joint_l joint_s joint_t joint_u ]

this indicates you either have no (MoveIt) controllers configured, or have not provided the correct configuration to those controllers (note: MoveIt controllers aren't really controllers, or at least not the 'controller' you'd have to use with motoman_driver. They are essentially action clients).

I had finished this erro by coping other demo

does this mean you've solved the problem, or is this an explanation for what you did in the past and what caused you to end up in this situation?
