Daikon Jackson XML

Project

https://github.com/DaikonWeb/daikon-jackson-xml

Methods

Daikon Gson adds one method to the Response and one to the Request in order to integrate easily the XML parsing with jackson library.

Request

.xml<MyClass>(): to deserialize an XML string to the desired class instance

Response

.xml(myInstance): to serialize a class instance to an XML string

How to use

Define data classes with appropriate XML annotations

@JacksonXmlRootElement(localName = "blackjackHand")
data class BlackjackHand(
    val hiddenCard: Card = Card(),
    @JacksonXmlElementWrapper(localName = "visibleCards") val card: List<Card> = mutableListOf()
)

data class Card(val rank: Char = '1', val suit: Suit = CLUBS)

enum class Suit {
    CLUBS, DIAMONDS, HEARTS;
}

Create a server and use the data class to read and produce XML

@Test
fun `xml request and response`() {
    HttpServer()
        .post("/") { req, res -> res.xml(req.xml<BlackjackHand>()) }
        .start().use {
            val response = "http://localhost:4545/".http.post(
                body = """<blackjackHand><hiddenCard><rank>4</rank><suit>CLUBS</suit></hiddenCard><visibleCards><card><rank>1</rank><suit>DIAMONDS</suit></card><card><rank>7</rank><suit>HEARTS</suit></card></visibleCards></blackjackHand>"""
            )
            assertThat(response.body).isEqualTo("""<blackjackHand><hiddenCard><rank>4</rank><suit>CLUBS</suit></hiddenCard><visibleCards><card><rank>1</rank><suit>DIAMONDS</suit></card><card><rank>7</rank><suit>HEARTS</suit></card></visibleCards></blackjackHand>""")
        }
}
