Installing and Using MongoDB in Grails 3.x
I followed Manning Grails In Action but their section on setting up data sources with legacy Grails 3.0 graphics. 3.
I intend to convert from default H2 data source to MongoDB version 3.0.2. Google searches came up with conflicting results. Many of the answers are often used for earlier versions of Grails that used "BuildConfig.groovy" and "DataSources.groovy" to create plugins and data sources.
I downloaded 3.0.2 JDBC for MongoDB and saved it in various folders (i.e. in the root application created by / lib / folder and / grails-app / conf /) with no success.
My application.yml file reads:

Yes, it is a problem finding modern documentation for configuring Grails 3.0 to use MongoDB. The solution below has been gleaned from various sources.
build.gradle
dependencies {
...
compile "org.grails.plugins:mongodb"
...
}
You don't need to manually download and install any JDBC files.
Grails application / CONF / application.yml
environments:
development:
grails:
mongodb:
connectionString: "mongodb://localhost:27017/project-db"
Grails application / domain / com / example / Book.groovy
package com.example
import org.bson.types.ObjectId
class Book {
ObjectId id
String title
static mapWith = "mongo"
}
I have used this approach successfully with Grails 3.0.1 and it still works with 3.0.4.

Dem Pilafyan is great and right. Mine is just a little different. You can leave the mapping in your classes and rely on mongodb to store your objects directly. All you have to do is remove hibernation from your project.
Using Grails 3.1.7
build.gradle
dependencies {
compile "org.grails.plugins:mongodb"
//compile "org.grails.plugins:hibernate4"
//compile "org.hibernate:hibernate-ehcache"
//runtime "com.h2database:h2"
}
I have commented out the hibernate and h2 dependencies. You can remove them entirely, of course, if you are only using mongodb.
Grails application / CONF / application.yml
environments:
development:
grails:
mongodb:
host: "hostname"
port: 27017
databaseName: development
In application.yml you need to remove the section hibernate:
and driverClassName: org.h2.Driver
. For more background information, as well as additional configuration options, see GORM Grails MongoDB
This way, you completely bypass hibernation and do not have to define the mapping in your classes. Your objects will be stored directly as structured documents in mongo.
