JarCastingJerkson
Because I think you should use JSON.
Jerkson is a Scala wrapper for Jackson which brings Scala's ease-of-use to Jackson's features. This library got started by codahale. I've just applied a bunch of the open pull requests and republished to maven.
Requirements
- Scala 2.8.2 or 2.9.1
- Jackson 1.9.x
Setting Up Your Project
Go ahead and add Jerkson as a dependency:
<dependencies>
<dependency>
<groupId>io.backchat.jerkson</groupId>
<artifactId>jerkson_${scala.version}</artifactId>
<version>0.6.0</version>
</dependency>
</dependencies>
Parsing JSON
import com.codahale.jerkson.Json._
// Parse JSON arrays
parse[List[Int]]("[1,2,3]") //=> List(1,2,3)
// Parse JSON objects
parse[Map[String, Int]]("""{"one":1,"two":2}""") //=> Map("one"->1,"two"->2)
// Parse JSON objects as case classes
// (Parsing case classes isn't supported in the REPL.)
case class Person(id: Long, name: String)
parse[Person]("""{"id":1,"name":"Coda"}""") //=> Person(1,"Coda")
// Parse streaming arrays of things
for (person <- stream[Person](inputStream)) {
println("New person: " + person)
}
For more examples, check out the specs.
Generating JSON
// Generate JSON arrays
generate(List(1, 2, 3)) //=> [1,2,3]
// Generate JSON objects
generate(Map("one"->1, "two"->"dos")) //=> {"one":1,"two":"dos"}
For more examples, check out the specs.
Handling snake_case Field Names
case class Person(firstName: String, lastName: String)
@JsonSnakeCase
case class Snake(firstName: String, lastName: String)
generate(Person("Coda", "Hale")) //=> {"firstName": "Coda","lastName":"Hale"}
generate(Snake("Windey", "Mover")) //=> {"first_name": "Windey","last_name":"Mover"}
