Create a Simple Connection With Vertx, MongoDB and Groovy

• You have to install VertX 3.3.3, Groovy, and Mongo DB.

• Create a simple groovy script

• Include the next imports

import io.vertx.groovy.core.Vertx
import io.vertx.groovy.ext.mongo.MongoClient

• Add the configuration for Mongo DB.

	def config = Vertx.currentContext().config()

	def uri = config.mongo_uri
	if (uri == null) {
		uri = "mongodb://localhost:27017"
	}

	def db = config.mongo_db
	if (db == null) {
	db = "test"//<---------------database name
	}

	def mongoconfig = [
	connection_string:uri,
	db_name:db
	]

def mongoClient = MongoClient.createShared(vertx, mongoconfig)

• Add some data in the script.

def person1 = [
	itemId:"12345",
	name:"Carlo",
	blog:"carlogilmar12@gmail.com",
	twitter:"karlosins"
]

• Use the mongo methods for save and find the data.

mongoClient.save("people", person1, { id ->
		println("Inserted id: ${id.result()}")

		mongoClient.find("people", [
				itemId:"12345"
		], { res ->
		println("Name is ${res.result()[0].name}")

	})

})

• Please, run the script with vertx run script.groovy

• You need to consult your Mongo Server

That’s a simple way for connect Mongo Db with VertX, thats the script complete:
