How to develop a REST Webservice method which accepts multiple URI

Question

How to develop a REST Webservice method which accepts multiple URIs for example

If we have a method

@RequestMapping(/add)
 public Response add(@RequestParam List elements){
  }

The method above serves for URL https://local host:8080/add

I have asked in interview how do we have a single Webservice which serves multiple URIs which I was not able to answer as I thought we should have unique URIs for each method
A follow up to this how do we have a method which returns the format whatever choosen (JSON, XML, PLAIN TEXT) from postman client.

Please take a look on [Multiple Spring @RequestMapping annotations](https://stackoverflow.com/questions/2513031/multiple-spring-requestmapping-annotations) — Volodymyr Demenkov, Apr 24 '18 at 10:04
You should be able to use `@RequestMapping(path={"/add", "/delete"})` and you can include `produces={"application/json", "text/xml"}`. — daniu, Apr 24 '18 at 10:06

Modify URI:

@RequestMapping(value = "/", produces = {
            MediaType.APPLICATION_JSON_VALUE,
            MediaType.APPLICATION_XML_VALUE
            })
public Response add(@RequestParam List elements){

}

Do we need to add all the mediatypes one by one. Dont we have a single option like MediaType.ALL or MediaType.Any – J123 Apr 24 '18 at 10:20
For all types, remove "produces". I thought you needed it – Alberto Apr 24 '18 at 10:37
So if I remove produces, then it accepts any Mediatype from postman client – J123 Apr 24 '18 at 11:03
Not necessarily. You can use `consumes` to define what type of data you want to accept – Alberto Apr 24 '18 at 11:07
No I want to accept any kind of data. Should I use produces or consumes – J123 Apr 25 '18 at 03:47
`consumes` => Data received from user. `produces` => Data sent to usere. If you want accept any data, remove `consumes` – Alberto Apr 25 '18 at 06:14

For the first question there is many ways to do that Spring restTemplate can allow you to call a rest service in another method so all you have to do is to call your rest service when another uri is requested You can also use proxies (web server proxies) to map same webservice to many URIs

For the second one you need to pass format as parameter and call specific service linked to format when executing

Hope that helps
