I have a search method and it has keywords parameter. What I want to do is set a default value(empty String array) to keywords parameter. Is there any way to do this?

@GetMapping(value = "search")
public List<Integer> search(@RequestParam String[] keywords){
 return calculate(Arrays.asList(keyword));
}

Try to use below:

@RequestParam(value="keywords[]", required=false) String[] keywords

or 

 @RequestParam(value=" ", required=false) String[] keywords

@RequestParam has an attribute defaultValue to set default value.

public List<Integer> search(@RequestParam(defaultValue="default value") String[] keywords){
 return calculate(Arrays.asList(keyword));
}
