New Rest end point created in Rest controller was not accessible

[mxm1008]

New Rest end point created in Rest controller was not accessible. 
The new Rest end point added under package com.activiti.extension.api.controller
with @RequestMapping(value = "/enterprise/ddms/users/addUsers", method = RequestMethod.POST, consumes = MediaType.APPLICATION_JSON_VALUE)

While calling the new end point, we are getting HTTP Status 404 – Not Found.
No mapping found for http request with uri /enterprise/ddms/users/addUsers in dispatcherservlet with name apidispatcher
Do we have any additional configuration for adding new end point?

Team, Could you please help on this?
