MapR-DB REST Application

This project shows how to integrate MapR-DB JSON and Java with the OJAI API to build a REST Application.

It contains:

A Main class that start Jetty Server and configure a REST Interface using JAX-RS
Swagger to easily access the API http
An Angular JS Application that consumes this API

In your MapR-DB environment, using a terminal, create the following folder, and change the permissions:

ssh mapr@maprdemo
 
cd /mapr/demo.mapr.com/

chmod 777 apps

mkdir apps/blog

chmod 777 apps/blog

Usage

Clone this repository, then

mvn clean package

To Run the application:

mvn exec:java -Dexec.mainClass="com.mapr.db.samples.rest.Main"

Once the server is started you can access the Swagger UI using the following URI:

Or the Web applications

You can use the Web application to create a user and a blog post.

Then in the Swagger UI you can discover some interesting features:

Create user from a predefined JSON Object (POJO)
Create user from "any" JSON String
List users using a simple projection
Update user to add a nickname, add interests, and remove these attributes. You see here the flexible schema in action
Query users by interest (list)
Similar features are exposed in the Articles REST API.
