RediSolar for Java

Introduction

This is the sample application codebase for RU102J, Redis for Java Developers at Redis University.

Solutions to the course programming challenges can be found on the solutions branch.

Prerequisites

In order to start and run this application, you will need:

  • Java 8 JDK or higher
  • Maven
  • Access to a local or remote installation of Redis version 5 or newer (local preferred)
  • If you want to try the RedisTimeSeries exercises, you'll need to make sure that your Redis installation also has the RedisTimeSeries Module installed

If you're using Windows, check out the following resources for help with running Redis:

How to Start the RediSolar Application

When using Redis on localhost, port 6379 with no password:

  1. Run mvn package to build your application.
  2. Load the sample data: java -jar target/redisolar-1.0.jar load. If you want to erase everything in Redis before loading the data, use java -jar target/redisolar-1.0.jar load --flush true, but be aware that this will delete ALL keys in your Redis database.
  3. Start the application with java -jar target/redisolar-1.0.jar server config.yml
  4. To check that your application is running enter url http://localhost:8081, substituting localhost for the hostname that you're running the application on if necessary.

When using Redis on another host, port or with a password:

  1. Edit config.yml, setting the values for your Redis host, port and password if needed.
  2. Edit src/test/java/com/redislabs/university/RU102J/HostPort.java, setting the values for your Redis host, port, and password if needed.
  3. Run mvn package to build your application.
  4. Load the sample data with java -jar target/redisolar-1.0.jar load --host <hostname> --port <port> --password <password>.
  5. Start application with java -jar target/redisolar-1.0.jar server config.yml.
  6. To check that your application is running enter url http://localhost:8081, substituting localhost for the hostname that you're running the application on if necessary.

Tests

To run all tests:

mvn test

To run a specific test:

mvn test -Dtest=JedisBasicsTest

Building

To rebuild the application:

mvn package

To rebuild the application without running the tests:

mvn package -DskipTests
