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");
