python服务重启（编译为exe时）

I have a service, as follows:

我有一项服务,如下:

"""
The most basic (working) CherryPy 3.1 Windows service possible.
Requires Mark Hammond's pywin32 package.

        try:

            self.iVal += 1 

            if self.iVal == 5:
                sys.exit()
            return "Hello world! " + str(self.iVal) 

        except SystemExit:
            StopServiceError(__builtin__.theService)
