Accessing Infinispan with a Redis Client

What You Will Learn

How to use a standard Redis client (Jedis) to connect to Infinispan via the RESP (Redis Serialization Protocol) endpoint and perform basic set/get operations.

Prerequisites

Java 17+
An Infinispan Server running on localhost:11222 (or Docker/Podman available for Testcontainers)

Step 1: Add the Jedis Dependency

Add the Jedis Redis client to your pom.xml:

<dependency>
   <groupId>redis.clients</groupId>
   <artifactId>jedis</artifactId>
   <version>${jedis.version}</version>
</dependency>

Step 2: Connect to Infinispan Using the Redis Protocol

Create a Jedis instance using a Redis URI with the Infinispan credentials:

      String redisUri = String.format("redis://%s:%s@%s:%s",
              TutorialsConnectorHelper.USER,
              TutorialsConnectorHelper.PASSWORD,
              TutorialsConnectorHelper.HOST,
              port);
      Jedis jedis = new Jedis(redisUri);

The tutorial automatically falls back to Testcontainers if no server is running locally.

Step 3: Perform Redis Operations

Use standard Redis commands to store and retrieve data from Infinispan:

      String key = "Hello";
      jedis.set(key, "world");
      String value = jedis.get(key);
      System.out.println(String.format("Read from Infinispan using a Redis Client (Resp Protocol): %s %s", key, value));

Step 4: Run the Tutorial

mvn package exec:java

You should see output like:

Read from Infinispan using a Redis Client (Resp Protocol): Hello world
