Quick start


<!-- JDK 1.8+ compatible -->

<!-- JDK 1.6+ compatible -->


// JDK 1.8+ compatible
compile 'org.redisson:redisson:3.7.5'  

// JDK 1.6+ compatible
compile 'org.redisson:redisson:2.12.5'


// 1. Create config object
Config = ...

// 2. Create Redisson instance
RedissonClient redisson = Redisson.create(config);

// 3. Get object you need
RMap<MyKey, MyValue> map = redisson.getMap("myMap");

RLock lock = redisson.getLock("myLock");

RExecutorService executor = redisson.getExecutorService("myExecutorService");

// over 30 different objects and services ...
