For example, in our controller:

@RequestMapping(value = "/customer/{id}", method = arrayOf(RequestMethod.GET))fun getCustomer(@PathVariable id: Int) = customers[id]

This parameter is actually an array, it can be changed, if required, to accept more than one method. For example, as:

@RequestMapping(value = "/customer/{id}", method = arrayOf(RequestMethod.GET, RequestMethod.POST))fun getCustomer(@PathVariable id: Int) = customers[id]

With this change, we set that we will accept either HTTP GET or HTTP POST in this method, however, we recommend you keep one method per function in ...
