Spring API Boolean Parameter Strict Validation-CodePudding

I wish to perform strict validation on a boolean parameter, seen below as "withDetails."

   @ApiResponses(value = {@ApiResponse(responseCode = "200", description = "Success")})
    @GetMapping(value = "/order", produces = "application/json")
    public ResponseEntity<ResponseClass> getOrders( String id,
            @RequestParam(value = "withDetails", defaultValue = "true")
            Boolean withDetails){
        ResponseClass responseClass = this.service.getResponse(id, withDetails);
        return ResponseEntity.ok(responseClass);
    }

Spring accepts non-boolean substitutions for this value, such as 0/1. This is apparently by design, as described here: https://stackoverflow.com/a/25123000/11994829

However, I want to strictly only allow "true/false" in requests. Can I do that while still defining the parameter as Boolean?

Try to create your own Converter:

@Component
public class BooleanConverter implements Converter<String, Boolean> {

    @Override
    public Boolean convert(String bool) {
        if ("true".equals(bool)) {
            return true;
        }
        if ("false".equals(bool)) {
            return false;
        }
        throw new IllegalArgumentException("Invalid boolean value '"   source   "'");
    }
}

In spring Boolean parameters have a value of 1/0 if you want to catch the value boolean type make parameter as String String withDetails and convert it .valueOf into boolean type (true\false) or you to make your own converter convert 1 as true and 0 as false
