Answer 1

if you want to use Square brackets - []

DELETE http://localhost:8080/public/test/[1,2,3,4]

@RequestMapping(value="/test/[{firstNameIds}]", method=RequestMethod.DELETE)
@ResponseBody
public String test(@PathVariable String[] firstNameIds)
{
    // firstNameIds: [1,2,3,4]
    return "Dummy"; 
}

(Tested with Spring MVC 4.1.1)

Answer 2

Could do @PathVariable String ids, then parse the string.

So something like:

@RequestMapping(value="/test/{firstNameIds}", method=RequestMethod.GET)
@ResponseBody
public String test(@PathVariable String firstNameIds)
{
     String[] ids = firstNameIds.split(",");
     return "Dummy"; 
}

You'd pass in:

http://localhost:8080/public/test/1,3,4,50

Answer 3

GET http://localhost:8080/public/test/1,2,3,4

@RequestMapping(value="/test/{firstNameIds}", method=RequestMethod.GET)
@ResponseBody
public String test(@PathVariable String[] firstNameIds)
{
    // firstNameIds: [1,2,3,4]
    return "Dummy"; 
}

(tested with Spring MVC 4.0.1)

Answer 4

You should do something like this:

Call:

GET http://localhost:8080/public/test/1,2,3,4

Your controller:

@RequestMapping(value="/test/{firstNameIds}", method=RequestMethod.GET)
@ResponseBody
public String test(@PathVariable List<Integer> firstNameIds) {
     //Example: pring your params
     for(Integer param : firstNameIds) {
        System.out.println("id: " + param);
     }
     return "Dummy";
}

Answer 5

At first, put this in your code (Add @PathVariable) :

@GetMapping(path="/test/{firstNameIds}",produces = {"application/json"})
public String test(@PathVariable List<String> firstNameIds)
{
     return "Dummy"; 
}

You'd pass in: http://localhost:8080/public/test/Agent,xxx,yyyy
