How to validate path parameter in microprofile - quarkus

Question

Here key is pathParam. And even if I send the value of key greater than 9. It sends me valid response, instead of throwing validation error.
Curl request -
curl --location --request GET 'localhost:8080/v1/batch-tokens/11/action/count'
Code -
#Path("/v1/batch-tokens")
public class BatchTokenResource implements Serializable {
private static final Logger LOGGER = Logger.getLogger(BatchTokenResource.class.getName());
private static final String LOG_HEADER = "[" + BatchTokenResource.class.getSimpleName() + "]::";
#GET
#Path("/{key}/action/count")
public Response countTokenPerKey(
#PathParam("key") #Min(value = 0) #Max(value = 9)
#Pattern(regexp = "^\\d$") String key
) {
LOGGER.log(Level.INFO, () -> LOG_HEADER + "countTokenPerKey " +
"key=" + key
);
try {
Long tokenCount = 100L;
return Response.ok(new TokenModel(key, tokenCount)).build();
} catch (Exception ex) {
LOGGER.log(Level.WARNING, () -> LOG_HEADER + "countTokenPerKey failed." +
"key=" + key +
"exception=" + ex.getMessage()
);
throw ex;
}
}
}
I tried searching on quarkus.io/guide and internet, but only found docs to validate bean parameters.
Guide for validating bean parameters:
https://quarkus.io/guides/validation

Answer 1

Looks like the culprit is the type of the parameter:
String key
https://javadoc.io/doc/jakarta.validation/jakarta.validation-api/latest/jakarta/validation/constraints/Max.html
Supported types are:
BigDecimal
BigInteger
byte, short, int, long, and their respective wrappers
Note that double and float are not supported due to rounding errors (some providers might provide some approximative support).
