提供一個JedisConnectionFactory 根據配置來判斷 單點 集群 還是哨兵

@Bean @ConditionalOnMissingBean public JedisConnectionFactory jedisConnectionFactory() { JedisConnectionFactory factory = null; String[] split = node.split(','); Set<HostAndPort> nodes = new LinkedHashSet<>(); for (int i = 0; i < split.length; i++) { try { String[] split1 = split[i].split(':'); nodes.add(new HostAndPort(split1[0], Integer.parseInt(split1[1]))); } catch (Exception e) { throw new RuntimeException(String.format('出現配置錯誤!請確認node=[%s]是否正確', node)); } } //獲得默認的連接池構造器(怎么設計的，為什么不抽象出單獨類，供用戶使用呢) 有毒 JedisClientConfiguration.JedisPoolingClientConfigurationBuilder jpcb = (JedisClientConfiguration.JedisPoolingClientConfigurationBuilder) JedisClientConfiguration.builder(); //指定jedisPoolConifig來修改默認的連接池構造器（真麻煩，濫用設計模式?。?！?。。? jpcb.poolConfig(jedisPoolConfig); //通過構造器來構造jedis客戶端配置 JedisClientConfiguration jedisClientConfiguration = jpcb.build(); //如果是哨兵的模式 if (!StringUtils.isEmpty(sentinel)) { logger.info('Redis use SentinelConfiguration'); RedisSentinelConfiguration redisSentinelConfiguration = new RedisSentinelConfiguration(); String[] sentinelArray = sentinel.split(','); for (String s : sentinelArray) { try { String[] split1 = s.split(':'); redisSentinelConfiguration.addSentinel(new RedisNode(split1[0], Integer.parseInt(split1[1]))); } catch (Exception e) { throw new RuntimeException(String.format('出現配置錯誤!請確認node=[%s]是否正確', node)); } } factory = new JedisConnectionFactory(redisSentinelConfiguration, jedisClientConfiguration); } //如果是單個節點 用Standalone模式 else if (nodes.size() == 1) { logger.info('Redis use RedisStandaloneConfiguration'); for (HostAndPort n : nodes) { RedisStandaloneConfiguration redisStandaloneConfiguration = new RedisStandaloneConfiguration(); if (!StringUtils.isEmpty(password)) { redisStandaloneConfiguration.setPassword(RedisPassword.of(password)); } redisStandaloneConfiguration.setPort(n.getPort()); redisStandaloneConfiguration.setHostName(n.getHost()); factory = new JedisConnectionFactory(redisStandaloneConfiguration, jedisClientConfiguration); } } //集群配置信息實現 else { logger.info('Redis use RedisStandaloneConfiguration'); RedisClusterConfiguration redisClusterConfiguration = new RedisClusterConfiguration(); nodes.forEach(n -> { redisClusterConfiguration.addClusterNode(new RedisNode(n.getHost(), n.getPort())); }); if (!StringUtils.isEmpty(password)) { redisClusterConfiguration.setPassword(RedisPassword.of(password)); } redisClusterConfiguration.setMaxRedirects(maxRedirect); factory = new JedisConnectionFactory(redisClusterConfiguration, jedisClientConfiguration); } return factory; }

配置文件

1.yml配置

1.1支持 Cluster模式 集群

spring: redis: node: 127.0.0.1:1001,127.0.0.1:1002,127.0.0.1:1003 password: 123456

properties配置

spring.redis.node=127.0.0.1:1001,127.0.0.1:1002,127.0.0.1:1003spring.redis.password=123456

1.2支持 Standalone模式 單點

node里只有一個redis地址的時候,會自動變成單點模式 yml配置

spring: redis: node: 127.0.0.1:1001 password: 123456

properties配置

spring.redis.node=127.0.0.1:1001spring.redis.password=123456

1.3支持 Sentinel模式 哨兵

當配置上sentinel以后就變成了哨兵模式 多個哨兵可以以逗號分割 yml配置

spring: redis: node: 127.0.0.1:1001 sentinel:127.0.0.1:1002,127.0.0.1:1003 password: 123456

properties配置

spring.redis.node=127.0.0.1:1001spring.redis.sentinel:127.0.0.1:1002,127.0.0.1:1003spring.redis.password=123456

1.4覆蓋默認配置

如果沒有配置這些信息,就會走默認配置 也可以在properties或者yml覆蓋默認配置

#最大連接數, 默認值8個spring.redis.jedis.pool.max-total=8#最大空閑連接數, 默認8個spring.redis.jedis.pool.max-idle=8#最小空閑連接數, 默認0spring.redis.jedis.pool.min-idle=0#獲取連接時的最大等待毫秒數,如果超時就拋異常, 小于零:阻塞不確定的時間, 默認-1spring.redis.jedis.pool.max-wait=-1#對拿到的connection進行validateObject校驗spring.redis.jedis.pool.test-on-borrow=true#集群時最大重定向個數默認5spring.redis.jedis.factory.max-redirects=5

使用

代碼使用

@Autowired private RedisTemplate<String, Object> redisTemplate;
