单机配置

redis.properties配置

#redis的服务器地址
redis.host=127.0.0.1

#redis的服务端口
redis.port=6379

#客户端超时时间单位是毫秒
redis.timeout=100000

#最大建立连接等待时间
redis.maxWaitMillis=1000

#最小空闲数
redis.minIdle=5

#最大空闲数
redis.maxIdle=20

#最大连接数
redis.maxTotal=100

自2.0开始，针对单机配置引入RedisStandaloneConfiguration 并且废弃了JedisConnectionFactory的HostName，Port，Password等属性的配置。

    /**
 * 连接工厂类
 * @return
 */
@Bean
public JedisConnectionFactory jedisConnectionFactory(){
    // 单机配置
    RedisStandaloneConfiguration standaloneConfig = new RedisStandaloneConfiguration();
    standaloneConfig.setHostName("127.0.01");
    standaloneConfig.setPort(6379);
    
    JedisConnectionFactory connectionFactory = new JedisConnectionFactory(standaloneConfig);
    
    return connectionFactory;
}

哨兵配置

为了处理高可用性的Redis，可以使用RedisSentinelConfiguration支持Redis Sentinel。

/**
* jedis
*/
@Bean
public RedisConnectionFactory jedisConnectionFactory() {
    RedisSentinelConfiguration sentinelConfig = new RedisSentinelConfiguration()
      .master("mymaster")
      .sentinel("127.0.0.1", 26379)
      .sentinel("127.0.0.1", 26380);
    return new JedisConnectionFactory(sentinelConfig);
}

可以配置的属性：
spring.redis.sentinel.master：master节点的名字
spring.redis.sentinel.nodes：主机:端口的逗号分隔列表

集群配置

 @Bean
public JedisConnectionFactory redisConnectionFactory() {
   JedisConnectionFactory connectionFactory = new JedisConnectionFactory();
   // 集群配置
   RedisClusterConfiguration redisClusterConfiguration = new RedisClusterConfiguration();
   RedisNode redisNode7000 = new RedisNode("10.1.21.4", 7000);
   RedisNode redisNode7001 = new RedisNode("10.1.21.4", 7001);
   RedisNode redisNode7002 = new RedisNode("10.1.21.4", 7002);
   RedisNode redisNode7003 = new RedisNode("10.1.21.4", 7003);
   RedisNode redisNode7004 = new RedisNode("10.1.21.4", 7004);
   RedisNode redisNode7005 = new RedisNode("10.1.21.4", 7005);

   redisClusterConfiguration.addClusterNode(redisNode7000);
   redisClusterConfiguration.addClusterNode(redisNode7001);
   redisClusterConfiguration.addClusterNode(redisNode7002);
   redisClusterConfiguration.addClusterNode(redisNode7003);
   redisClusterConfiguration.addClusterNode(redisNode7004);
   redisClusterConfiguration.addClusterNode(redisNode7005);
   connectionFactory = new JedisConnectionFactory(redisClusterConfiguration);

   // 设置连接池配置
   connectionFactory.setPoolConfig(jedisConfig());

   // 设置数据库，默认0
   connectionFactory.setDatabase(2);

   // 设置使用连接池
   connectionFactory.setUsePool(true);

   return connectionFactory;
}

配置说明

1. 以上配置是基于Jedis客户端的
2. 使用javaCode或者xml的配置方式依据个人喜好
