Usage examples
####Simple config example
// connects to Redis server 127.0.0.1:6379 by default
Redisson redisson = Redisson.create();
...
redisson.shutdown();
or with initialization by Config object
Config config = new Config();
config.setConnectionPoolSize(10);
config.addAddress("some.server.com:8291");
Redisson redisson = Redisson.create(config);
...
redisson.shutdown();
####Distributed Map example
Redisson redisson = Redisson.create();
ConcurrentMap<String, SomeObject> map = redisson.getMap("anyMap");
map.put("123", new SomeObject());
map.putIfAbsent("323", new SomeObject());
map.remove("123");
...
redisson.shutdown();
####Distributed Set example
Redisson redisson = Redisson.create();
Set<SomeObject> set = redisson.getSet("anySet");
set.add(new SomeObject());
set.remove(new SomeObject());
...
redisson.shutdown();
####Distributed List example
Redisson redisson = Redisson.create();
List<SomeObject> list = redisson.getList("anyList");
list.add(new SomeObject());
list.get(0);
list.remove(new SomeObject());
...
redisson.shutdown();
####Distributed Queue example
Redisson redisson = Redisson.create();
Queue<SomeObject> queue = redisson.getQueue("anyQueue");
queue.add(new SomeObject());
queue.peek();
queue.pool();
...
redisson.shutdown();
####Distributed Lock example
Redisson redisson = Redisson.create();
Lock lock = redisson.getLock("anyLock");
lock.lock();
lock.unlock();
// same as
redisson.getLock("anyLock").lock();
...
redisson.getLock("anyLock").unlock();
...
redisson.shutdown();
####Distributed AtomicLong example
Redisson redisson = Redisson.create();
RAtomicLong atomicLong = redisson.getAtomicLong("anyAtomicLong");
atomicLong.set(3);
atomicLong.incrementAndGet();
atomicLong.get();
...
redisson.shutdown();
####Distributed CountDownLatch example
Redisson redisson = Redisson.create();
RCountDownLatch latch = redisson.getCountDownLatch("anyCountDownLatch");
latch.trySetCount(1);
latch.await();
// in other thread or other JVM
RCountDownLatch latch = redisson.getCountDownLatch("anyCountDownLatch");
latch.countDown();
...
redisson.shutdown();
####Distributed Topic example
Redisson redisson = Redisson.create();
RTopic<SomeObject> topic = redisson.getTopic("anyTopic");
topic.addListener(new MessageListener<SomeObject>() {
public void onMessage(SomeObject message) {
...
}
});
// in other thread or other JVM
RTopic<SomeObject> topic = redisson.getTopic("anyTopic");
topic.publish(new SomeObject());
...
redisson.shutdown();
