Jackson Codec
===================

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

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

```java
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`:

```java
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");
```

Alternatively, you can add the encoder and decoder to your Dagger object graph using the provided `JacksonModule` like so:

```java
GitHub github = Feign.create(GitHub.class, "https://api.github.com", new JacksonModule());
```
