springboot整合redis(单机、主从哨兵、集群)

1、配置

1.1、配置图解

2、验证

2.1、程序启动

主从模式

集群模式

2.2、测试

2.3、stop-master

2.4、stop-master-again

2.5、数据同步

3、其它事项

3.1、down-after-milliseconds

#master或slave多长时间（默认30秒）不能使用后标记为s_down状态。 sentinel down-after-milliseconds mymaster 3000 (可改为3秒)
redis哨兵sentinel.config中配置，程序无法处理

3.2、failover-timeout mymaster

#若哨兵在配置值内未能完成故障转移操作(默认180000)，则任务本次故障转移失败
sentinel failover-timeout mymaster 18000
redis哨兵 sentinel.config中配置，程序无法处理

4、测试controller

@GetMapping(path = "/redisTest", produces = MediaType.APPLICATION_JSON_VALUE)
	public String redisTest() {
		log.info("redisTest - start ");
		// 1> 参数验证
		try {
			Date date = new Date();
			DateFormat df = new SimpleDateFormat("yyyyMMddHHmmss");
			String aa = df.format(date);
			String key = "key:" + aa;
			redisClient.set("key:" + aa, aa, 100, TimeUnit.SECONDS);
			System.err.println("set success");
			String test = redisClient.get(key);
			System.err.println("get -> " + test);
		}catch (NullPointerException | IllegalArgumentException e) {
			log.error("error : {} . ", e);
			return e.getMessage();
		}catch (Exception e) {
			log.error("error : {} . ", e);
			return e.getMessage();
		}
		log.info("redisTest - end ");

		log.info("lock - check - start . ");
		try {
			RLock lock = redisClient.getLock("test-lock");
			try {
				lock.lock();
				System.err.println("redisLock执行中");
				new Thread(new Runnable() {
					@Override
					public void run() {
						RLock lock = redisClient.getLock("test-lock");
						try {
							lock.lock();
							System.err.println("redisLock2执行中.......");
						} finally {
							if (lock != null) {
								lock.unlock();
							}
							System.err.println("redisLock2执行结束");
						}
					}
				}).start();
				Thread.sleep(1000 * 5);
			} finally {
				if (lock != null) {
					lock.unlock();
				}
				System.err.println("redisLock执行结束");
			}
			Thread.sleep(1000 * 3);
			log.info("lock - check - end . ");
			return "lock";
		}catch (NullPointerException | IllegalArgumentException e) {
			log.error("error : {} . ", e);
			return e.getMessage();
		}catch (Exception e) {
			log.error("error : {} . ", e);
			return e.getMessage();
		}
	}
