Quick start

Maven

<dependency>
   <groupId>org.redisson</groupId>
   <artifactId>redisson</artifactId>
   <version>3.29.0</version>
</dependency>

Gradle

compile 'org.redisson:redisson:3.29.0'

SBT

libraryDependencies += "org.redisson" % "redisson" % "3.29.0"

Java

// 1. Create config object
Config config = new Config();
config.useClusterServers()
       // use "rediss://" for SSL connection
      .addNodeAddress("redis://127.0.0.1:7181");

// or read config from file
config = Config.fromYAML(new File("config-file.yaml"));

// 2. Create Redisson instance

// Sync and Async API
RedissonClient redisson = Redisson.create(config);

// Reactive API
RedissonReactiveClient redissonReactive = redisson.reactive();

// RxJava3 API
RedissonRxClient redissonRx = redisson.rxJava();

// 3. Get Redis based implementation of java.util.concurrent.ConcurrentMap
RMap<MyKey, MyValue> map = redisson.getMap("myMap");

RMapReactive<MyKey, MyValue> mapReactive = redissonReactive.getMap("myMap");

RMapRx<MyKey, MyValue> mapRx = redissonRx.getMap("myMap");

// 4. Get Redis based implementation of java.util.concurrent.locks.Lock
RLock lock = redisson.getLock("myLock");

RLockReactive lockReactive = redissonReactive.getLock("myLock");

RLockRx lockRx = redissonRx.getLock("myLock");

// 4. Get Redis based implementation of java.util.concurrent.ExecutorService
RExecutorService executor = redisson.getExecutorService("myExecutorService");

// over 50 Redis based Java objects and services ...
