Quick Start Java Spring Boot & MongoDB Client Side Field Level Encryption

This is a demo springboot application created using IntelliJ Spring Initialzr which will show case basic CRUD and Automatic CSFLE (Client Side Field Level Encryption) with MongoDB Atlas.

This demo connects to MongoDB Atlas using a Java Spring Boot Application with Personal Identifiable Information (PII) data automatically encrypted before sending it to the database.

Supported versions:

• Java 11
• Spring boot 2.7.10
• Spring Data MongoDB
• MongoDB Atlas
• Maven

MongoDB Atlas

• Get started with a Free Tier Cluster on MongoDB Atlas.
• Read this blog post: Quick Start - Getting your Free MongoDB Atlas Cluster.

How To Run

• Create a file src/main/resources/mongodb.properties and add the following entries:
  • MongoDB URI spring.data.mongodb.uri
  • database spring.data.mongodb.database
  • collection spring.data.mongodb.collection
  • path to your mongo_crypt_shared library crypt.shared.lib.path

Then you can run as a Spring Boot Application or just run the class JavaSpringBootCSFLEApplication.java.

Commands

• Start the server in a console with mvn spring-boot:run.
• If you add some Unit Tests, you would start them with mvn clean test.
• You can build the project with mvn clean package.
