An extension for Google's AutoValue that creates a simple Moshi JsonAdapterFactory for each AutoValue annotated object.
Simply include auto-value-moshi in your project and add a public static method with the following
signature to classes you want to get Moshi JsonAdapter
s. You can also annotate your properties
using @Json
to define an alternate name for de/serialization.
@AutoValue public abstract class Foo {
abstract String bar();
@Json(name="Baz") abstract String baz();
public static JsonAdapter<Foo> jsonAdapter(Moshi moshi) {
return new AutoValue_Foo.MoshiJsonAdapter(moshi);
}
}
Now build your project and de/serialize your Foo.
Optionally, auto-value-moshi can create a single JsonAdapter.Factory so that you don't have to add each generated JsonAdapter to your Moshi instance manually.
To generate a JsonAdapter.Factory
for all of your auto-value-moshi classes, simply create
an abstract class that implements JsonAdapter.Factory
and annotate it with @MoshiAdapterFactory
,
and auto-value-moshi will create an implementation for you. You simply need to provide a static
factory method, just like your AutoValue classes, and you can use the generated JsonAdapter.Factory
to help Moshi de/serialize your types.
@MoshiAdapterFactory
public abstract class MyAdapterFactory implements JsonAdapter.Factory {
// Static factory method to access the package
// private generated implementation
public static JsonAdapter.Factory create() {
return new AutoValueMoshi_MyAdapterFactory();
}
}
Then you simply need to register the Factory with Moshi.
Moshi moshi = new Moshi.Builder()
.add(MyAdapterFactory.create())
.build();
Add a Gradle dependency:
apt 'com.ryanharter.auto.value:auto-value-moshi:0.4.3'
// if you use the @MoshiAdapterFactory annotation, you'll need to add the 'annotations' artifact
// as a provided dependency:
provided 'com.ryanharter.auto.value:auto-value-moshi-annotations:0.4.3'
(Using the android-apt plugin)
