Learn Groovy

If you are new to Groovy or to programming (coding) at all, here are some tips how to get used to it, before you start messing with Boomi.

1. https://groovy-lang.org/

2. Buy a book: Groovy in Action, Second Edition ( v2.4 -> published 2015 )

   1. -> read it !

3. Create a new Groovy Test project in IntelliJ

New Groovy.Test Project

and learn the language.

The Groovy.Test project in action

Fix the main.groovy code to make it look similar to Boomi, without a main() method:

println "Hello world!"

String name = "Markus"
println( "Hello $name")

Run it, debug it, extend it .. learn Groovy!

Start playing

import groovy.json.JsonOutput
import groovy.json.JsonSlurper

def js = new JsonSlurper()
def json = js.parseText('''
  { "firstname" : "Markus",  
    "lastname" : "Schmidt" }
''')

// See output with [] --> Map = KeyValue Array/List
println(json)
println("-----")

String text = JsonOutput.toJson(json)
println(JsonOutput.prettyPrint(text))
