核心代碼段

提供一個(gè)JedisConnectionFactory  根據(jù)配置來判斷 單點(diǎn) 集群 還是哨兵

 @Bean
 @ConditionalOnMissingBean
 public JedisConnectionFactory jedisConnectionFactory() {
  JedisConnectionFactory factory = null;
 
  String[] split = node.split(",");
  Set 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(xiàn)配置錯(cuò)誤!請(qǐng)確認(rèn)node=[%s]是否正確", node));
   }
  }
  //獲得默認(rèn)的連接池構(gòu)造器(怎么設(shè)計(jì)的，為什么不抽象出單獨(dú)類，供用戶使用呢) 有毒
  JedisClientConfiguration.JedisPoolingClientConfigurationBuilder jpcb =
    (JedisClientConfiguration.JedisPoolingClientConfigurationBuilder) JedisClientConfiguration.builder();
  //指定jedisPoolConifig來修改默認(rèn)的連接池構(gòu)造器（真麻煩，濫用設(shè)計(jì)模式?。??。。?！
  jpcb.poolConfig(jedisPoolConfig);
  //通過構(gòu)造器來構(gòu)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(xiàn)配置錯(cuò)誤!請(qǐng)確認(rèn)node=[%s]是否正確", node));
    }
   }
   factory = new JedisConnectionFactory(redisSentinelConfiguration, jedisClientConfiguration);
 
  }
  //如果是單個(gè)節(jié)點(diǎn) 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(shí)現(xiàn)
  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;
 }
