Jackson Codec

This module adds support for encoding and decoding JSON via Jackson.

Add JacksonEncoder and/or JacksonDecoder to your Feign.Builder like so:

GitHub github = Feign.builder()
                     .encoder(new JacksonEncoder())
                     .decoder(new JacksonDecoder())
                     .target(GitHub.class, "https://api.github.com");

If you want to customize the ObjectMapper that is used, provide it to the JacksonEncoder and JacksonDecoder:

ObjectMapper mapper = new ObjectMapper()
        .setSerializationInclusion(JsonInclude.Include.NON_NULL)
        .configure(SerializationFeature.INDENT_OUTPUT, true)
        .configure(DeserializationFeature.FAIL_ON_UNKNOWN_PROPERTIES, false);

GitHub github = Feign.builder()
                     .encoder(new JacksonEncoder(mapper))
                     .decoder(new JacksonDecoder(mapper))
                     .target(GitHub.class, "https://api.github.com");
