This module adds support for encoding and decoding JSON via Fastjson2.
Add Fastjson2Codec to your Feign.Builder like so:
GitHub github = Feign.builder()
.codec(new Fastjson2Codec())
.target(GitHub.class, "https://api.github.com");You can also configure the encoder and decoder separately:
GitHub github = Feign.builder()
.encoder(new Fastjson2Encoder())
.decoder(new Fastjson2Decoder())
.target(GitHub.class, "https://api.github.com");If you want to customize, provide features to the Fastjson2Codec:
GitHub github = Feign.builder()
.codec(new Fastjson2Codec(
new JSONWriter.Feature[]{JSONWriter.Feature.WriteNonStringValueAsString},
new JSONReader.Feature[]{JSONReader.Feature.EmptyStringAsNull}))
.target(GitHub.class, "https://api.github.com");
