Overview of this book

MongoDB is a high-performance and feature-rich NoSQL database that forms the backbone of the systems that power many different organizations – it’s easy to see why it’s the most popular NoSQL database on the market. Packed with many features that have become essential for many different types of software professionals and incredibly easy to use, this cookbook contains many solutions to the everyday challenges of MongoDB, as well as guidance on effective techniques to extend your skills and capabilities. This book starts with how to initialize the server in three different modes with various configurations. You will then be introduced to programming language drivers in both Java and Python. A new feature in MongoDB 3 is that you can connect to a single node using Python, set to make MongoDB even more popular with anyone working with Python. You will then learn a range of further topics including advanced query operations, monitoring and backup using MMS, as well as some very useful administration recipes including SCRAM-SHA-1 Authentication. Beyond that, you will also find recipes on cloud deployment, including guidance on how to work with Docker containers alongside MongoDB, integrating the database with Hadoop, and tips for improving developer productivity. Created as both an accessible tutorial and an easy to use resource, on hand whenever you need to solve a problem, MongoDB Cookbook will help you handle everything from administration to automation with MongoDB more effectively than ever before.

Accessing MongoDB using JPA


In this recipe, we will use a JPA provider that allows us to use JPA entities to achieve object-to-document mapping with MongoDB.

Getting ready

Start the standalone server instance listening to port 27017. This is a Java project using JPA. Familiarity with JPA and its annotations is expected, though what we will be looking at is fairly basic. Refer to the Connecting to the single node using a Java client recipe in Chapter 1, Installing and Starting the Server, to see how to set up maven if you are not aware of it. Download the DataNucleusMongoJPA project from the bundle provided with this book. Though we will be executing the test cases from the command prompt, you can import the project to your favorite IDE to view the source code.

How to do it…

  1. Go to the root directory of the DataNucleusMongoJPA project and execute the following in the shell:

    $ mvn clean test
    
  2. This should download the necessary artifacts needed to build and run the project and execute the test cases...
