Jackson Jr Codec
|
||
|
|
===================
|
||
|
|
|
||
|
|
This module adds support for encoding and decoding JSON via Jackson Jr. This
|
||
|
|
is a significantly smaller and faster version of Jackson, which may be of benefit
|
||
|
|
in smaller runtime containers.
|
||
|
|
|
||
|
|
Add `JacksonJrEncoder` and/or `JacksonJrDecoder` to your `Feign.Builder` like so:
|
||
|
|
|
||
|
|
```java
|
||
|
|
GitHub github = Feign.builder()
|
||
|
|
.encoder(new JacksonJrEncoder())
|
||
|
|
.decoder(new JacksonJrDecoder())
|
||
|
|
.target(GitHub.class, "https://api.github.com");
|
||
|
|
```
|
||
|
|
|
||
|
|
If you want to customize the `JSON` object that is used, provide it to the `JacksonJrEncoder` and `JacksonJrDecoder`:
|
||
|
|
|
||
|
|
```java
|
||
|
|
JSON json = Json.builder()
|
||
|
|
.register(JacksonAnnotationExtension.builder()
|
||
|
|
.withVisibility(JsonAutoDetect.Value.defaultVisibility())
|
||
|
|
.build())
|
||
|
|
.build();
|
||
|
|
|
||
|
|
GitHub github = Feign.builder()
|
||
|
|
.encoder(new JacksonJrEncoder(json))
|
||
|
|
.decoder(new JacksonJrDecoder(json))
|
||
|
|
.target(GitHub.class, "https://api.github.com");
|
||
|
|
```
|
||
|
|
|
||
|
|
Customisation is also possible by passing `JacksonJrExtension` objects
|
||
|
|
into the constructor of the `JacksonJrEncoder` or `JacksonJrDecoder`:
|
||
|
|
|
||
|
|
```java
|
||
|
|
List<JacksonJrExtension> extensions = singletonList(JacksonAnnotationExtension.builder()
|
||
|
|
.withVisibility(JsonAutoDetect.Value.defaultVisibility())
|
||
|
|
.build());
|
||
|
|
GitHub github = Feign.builder()
|
||
|
|
.encoder(new JacksonJrEncoder(extensions))
|
||
|
|
.decoder(new JacksonJrDecoder(extensions))
|
||
|
|
.target(GitHub.class, "https://api.github.com");
|
||
|
|
```
