Avaje-JsonB

JSON support using Avaje-JsonB library.

Usage

1) Add the dependency:

.

2) Install and encode/decode JSON

Java

import io.jooby.avaje.jsonb.AvajeJsonbModule;

{
  install(new AvajeJsonbModule());                  (1)

  get("/", ctx -> {
    MyObject myObject = ...;
    return myObject;                                (2)
  });

  post("/", ctx -> {
    MyObject myObject = ctx.body(MyObject.class);   (3)
    ...
  });
}

Kotlin

import io.jooby.avaje.jsonb.AvajeJsonbModule

{
  install(AvajeJsonbModule())                       (1)

  get("/") {
    val myObject = ...;
    myObject                                        (2)
  }

  post("/") {
    val myObject = ctx.body<MyObject>()             (3)
    ...
  }
}

1. Install Avaje-JsonB

2. Use Avaje-JsonB to encode arbitrary object as JSON

3. Use Avaje-JsonB to decode JSON to Java object. Client must specify the Content-Type: application/json header

Working with Jsonb

Access to default Jsonb is available via require call:

Default Jsonb

import io.jooby.avaje.jsonb.AvajeJsonbModule;
import io.avaje.jsonb.Jsonb;

{
  install(new AvajeJsonbModule());

  Jsonb jsonb = require(Jsonb.class);

  ...
}

Kotlin

import io.jooby.avaje.jsonb.AvajeJsonbModule
import io.avaje.jsonb.Jsonb

{
  install(AvajeJsonbModule())

  val jsonb = require<Jsonb>()
}

You can provide your own Jsonb:

Custom Jsonb

import io.jooby.avaje.jsonb.AvajeJsonbModule;
import io.avaje.jsonb.Jsonb;

{
  var jsonb = Jsonb.builder().build();

  install(new AvajeJsonbModule(jsonb));
}

Kotlin

import io.jooby.avaje.jsonb.AvajeJsonbModule
import io.avaje.jsonb.Jsonb

{
  var jsonb = Jsonb.builder().build()

  install(AvajeJsonbModule(jsonb))
}
