doNotCloseAfterDecode

public B doNotCloseAfterDecode()

This flag indicates that the response should not be automatically closed upon completion of decoding the message. This should be set if you plan on processing the response into a lazy-evaluated construct, such as a Iterator.

Feign standard decoders do not have built in support for this flag. If you are using this flag, you MUST also use a custom Decoder, and be sure to close all resources appropriately somewhere in the Decoder (you can use Util.ensureClosed(java.io.Closeable) for convenience).

9.6

queryMapEncoder

public B queryMapEncoder(QueryMapEncoder queryMapEncoder)

mapAndDecode

public B mapAndDecode(ResponseMapper mapper,
                      Decoder decoder)

Allows to map the response before passing it to the decoder.

dismiss404

public B dismiss404()

This flag indicates that the decoder should process responses with 404 status, specifically returning null or empty instead of throwing FeignException.

All first-party (ex gson) decoders return well-known empty values defined by Util.emptyValueOf(java.lang.reflect.Type). To customize further, wrap an existing decoder or make your own.

This flag only works with 404, as opposed to all or arbitrary status codes. This was an explicit decision: 404 -> empty is safe, common and doesn't complicate redirection, retry or fallback policy. If your server returns a different status for not-found, correct via a custom client.

Since:

11.9
