Passing an Array or List to @Pathvariable - Spring/Java

Question

I am doing a simple 'get' in JBoss/Spring. I want the client to pass me an array of integers in the url. How do I set that up on the server? And show should the client send the message?

This is what I have right now.

@RequestMapping(value="/test/{firstNameIds}", method=RequestMethod.GET)
@ResponseBody
public String test(@PathVariable List<Integer> firstNameIds)
{
     //What do I do??
     return "Dummy"; 
}

On the client I would like to pass something like

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

When I did that I get an error:

java.lang.IllegalStateException: Could not find @PathVariable [firstNameIds] in @RequestMapping

Answer 1

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"; 
}
