JSON Extensions

Simple wrapper for json4s to simplify de/serialization of JSON.

Usage

Deserialize JSON to a Scala Case Class

import onema.json.Extensions._

case class TestJsonFoo(name: String, value: String, id: Int = 0)

val fooJson = "{\"name\": \"test\", \"value\": \"foo\"}"

val fooObject = fooJson.jsonDecode[TestJsonFoo]

fooObject.name should be("test")
fooObject.value should be("foo")
fooObject.id should be(0)

Serialize Scala Class to JSON string

import onema.json.Extensions._

case class Message(data: Seq[String])
val result = "{\"data\":[\"http://foo.com\",\"http://bar.com\",\"http://baz.com\",\"http://blah.org\"]}"
val message = Message(Seq("http://foo.com", "http://bar.com", "http://baz.com", "http://blah.org"))

val jsonValue = message.asJson

jsonValue should be(result)

Deserialize to Java POJO

import onema.json.JavaExtensions._

val fooJson = "{\"name\": \"test\", \"value\": \"foo\"}"

val fooObject = fooJson.jsonDecode[TestJsonPojo]

fooObject.getName should be("test")
fooObject.getValue should be("foo")
fooObject.getId should be(0)

Serialize java POJO to JSON string

import onema.json.JavaExtensions._

val result = "{\"data\":[\"http://foo.com\",\"http://bar.com\",\"http://baz.com\",\"http://blah.org\"]}"
val message = new TestJsonPojo()

val jsonValue = message.asJson

jsonValue should be(result)
