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";  } 

(tested with Spring MVC 4.0.1)

Answer 2

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"; }
