How to restrict REST parameters to enum in spring-mvc?

Question

I want to restrict REST service parameters by an enum as follows:

public class enum {
    TEST;
}

@RestController
public class MyRest {
   @RequestMapping(method = RequestMethod.GET)
   public Object content(@RequestParam value="list" required=false) List<MyEnum> list) {
    Sysout(list);
  }
}

This works great if I call: /app?list=TEST.

But when invoking /app?list=test (lowercase letters) the rest services does not respond.

How can I eg provide custom values for the enum types to be accepted?

Solution was to add the following into the rest service controller: `@InitBinder protected void initBinder(WebDataBinder binder) { binder.registerCustomEditor(MyEnum.class, new EnumConverter(MyEnum.class));}` — membersound, Jan 27 '15 at 10:32

I am not sure about the way you are doing it. But we can do it in another way.

public class enum {
  TEST(1, "TEST");
}

@RestController
public class MyRest {
  @RequestMapping(method = RequestMethod.GET)
  public Object content(@RequestParam value="list" required=false) List<Integer> list) {
    for(Integer int: list)
    sysout(enum.get(int));
  }
}

You can pass in a list of integers and map the enum against these int values. Passing a list of integers seems cleaner to me.

Thanks!!

well but I want my clients to trasmit string values explicit, so integers are no option. – membersound Jan 23 '15 at 14:01

If you want to convert an enum from an incoming string value use: MyEnum.valueOf(inputString.toUpperCase()); – Tim Schimandle Sep 22 '15 at 17:17
